When 7.59 grams of sodium hydroxide (NaOH) are dissolved in 80.0 grams of water at 25.0 °C in an insulated container, the temperature of the water increases to 48.0 °C. Assuming that the specific heat of the solution is 4.184 J/(g °C) and that no heat is gained or lost by the container, what is the ∆H of solution of NaOH in kJ/mol?

Answers

The ∆H of solution of NaOH is 46.8 kJ/mol.

First, we need to calculate the amount of heat absorbed by the solution:

q = m × c × ∆T

where q is the heat absorbed (in Joules), m is the mass of the solution (in grams), c is the specific heat capacity of the solution (in J/(g °C)), and ∆T is the change in temperature (in °C).

In this case, the mass of the solution is the sum of the mass of NaOH and the mass of water:

m = 7.59 g + 80.0 g = 87.59 g

The change in temperature is:

∆T = 48.0 °C - 25.0 °C = 23.0 °C

Substituting the values, we get:

q = 87.59 g × 4.184 J/(g °C) × 23.0 °C = 8,878 J

Next, we need to convert the heat absorbed into the enthalpy change of solution (∆H). The enthalpy change of solution is the heat absorbed per mole of solute. The number of moles of NaOH is:

n = m/M

where M is the molar mass of NaOH, which is 40.00 g/mol.

n = 7.59 g / 40.00 g/mol = 0.1898 mol

Therefore, the enthalpy change of solution is:

∆H = q/n = 8,878 J / 0.1898 mol = 46,780 J/mol = 46.78 kJ/mol

The H of a NaOH solution, rounded to three significant numbers, is 46.8 kJ/mol.

The energy required to dissociate the Cl2 molecule to Cl atoms is 239 kJ/mol Cl2. If the dissociation of a Cl2 molecule were accomplished by the absorption of a single photon whose energy was exactly the quantity required, what would be its wavelength (in meters)?​

Answers

Explanation:

The energy of a single photon can be calculated using the equation E = hc/λ, where E is the energy of the photon, h is Planck's constant (6.626 x 10^-34 J.s), c is the speed of light (2.998 x 10^8 m/s), and λ is the wavelength of the photon.

To dissociate one mole of Cl2 molecules, we need 239 kJ of energy. This corresponds to 239,000 J/mol of Cl2.

Now we can use the relationship between energy and the number of photons absorbed: E = Nhf, where N is the number of photons absorbed, h is Planck's constant, and f is the frequency of the absorbed photons.

We can relate the frequency of the absorbed photon to its wavelength using c = λf. Solving for f gives f = c/λ.

Combining these equations, we get E = Nh(c/λ), or N = E/(hc/λ). Substituting the value of E for the energy required to dissociate one mole of Cl2, we get:

N = (239,000 J/mol) / [(6.626 x 10^-34 J.s) x (2.998 x 10^8 m/s) / λ]

Solving for λ, we get:

λ = hc / (239,000 J/mol) = (6.626 x 10^-34 J.s x 2.998 x 10^8 m/s) / 239,000 J/mol

λ = 8.44 x 10^-7 m

Therefore, the wavelength of the photon required to dissociate one Cl2 molecule is approximately 8.44 x 10^-7 meters (or 844 nanometers).

Can someone help me please. Use your knowledge of waves and the electromagnetic spectra to explain how electromagnetic radiation affects molecules? Be sure to include 3 specific examples

Answers

Electromagnetic radiation affects molecules in several ways. When electromagnetic radiation interacts with molecules, it can cause the molecules to vibrate, rotate, and even dissociate. These effects are due to the absorption of energy from the electromagnetic radiation by the molecules.

Here are three specific examples of how electromagnetic radiation affects molecules:

1. Ultraviolet (UV) radiation: UV radiation has enough energy to break chemical bonds in molecules, which can lead to the formation of free radicals. Free radicals are highly reactive and can damage cells and DNA, leading to mutations and cancer. For example, UV radiation from the sun can cause thymine dimers in DNA, which can disrupt DNA replication and lead to mutations.

2. Infrared (IR) radiation: IR radiation can cause molecules to vibrate, which can lead to changes in the molecular structure and properties. For example, IR radiation can be used to identify the functional groups in a molecule, such as the C=O bond in a carbonyl group. The absorption of IR radiation by a molecule can also lead to the release of heat, which can be used in various applications, such as in infrared heaters.

3. X-rays: X-rays have enough energy to ionize molecules, which can lead to the formation of free radicals and other reactive species. The ionization of molecules by X-rays is used in medical applications, such as in radiation therapy for cancer. However, the ionization of molecules by X-rays can also lead to damage to healthy cells and tissues, which can lead to side effects.

In summary, electromagnetic radiation affects molecules by causing them to vibrate, rotate, dissociate, and even ionize. The specific effects of electromagnetic radiation on molecules depend on the energy and frequency of the radiation, as well as the properties of the molecules.

How has the increase in human population impacted earths resources?

Answers

Answer:

The increase in human population has impacted Earth's resources in several major ways:

• Increased demand for food, water, and shelter. A larger population requires massive increases in food, water, and living spaces which strains natural resources and infrastructure. Producing enough food alone is a significant challenge.

• Accelerated consumption of resources. As population grows, the use of resources like forests, minerals, fossil fuels also increases rapidly to meet demands. This accelerated depletion of resources threatens long term sustainability.

• Increased pollution. A bigger population produces more pollution, waste, emissions, and environmental degradation as a byproduct of energy usage, transportation, industrialization, and land/resource use. This pollution harms ecosystems and contaminates the air, water and land.

• Biodiversity loss. As natural habitats are destroyed or fragmented to enable more human use, many plant and animal species lose their homes and face a higher risk of extinction. Tropical rainforests, in particular, have been heavily impacted.

• Inequality. While resources are limited, population growth often exacerbates inequality in access to and distribution of resources. Poor or developing regions typically have the highest populations but fewest resources per capita.

• Migration and conflict. Shortages of resources in certain areas or regions may lead to migration, economic troubles, social unrest, and in some cases even resource conflicts or wars.

• Slower development. Extremely rapid population growth rates make it difficult for governments, organizations and societies to effectively manage development, improve standards of living, advance technology, and make other progress at an optimal pace. Slower, more stabilized population growth may enable a higher overall quality of life.

So in many profound and troubling ways, increased population size has created immense pressures on Earth's resources and made it more difficult to meet present and future needs in a sustainable manner. Most experts agree that slowing population growth is critical to ensuring resource security for future generations.

Thermodynamic properties of ethanol, how much heat is released when 60g of ethanol cools from 70C to 43C

Answers

The negative sign indicates that heat is being released from the ethanol as it cools down. So, 3,950.4 joules of heat are released when 60g of ethanol cools from 70°C to 43°C.

To calculate heat released when 60g of ethanol cools from 70°C to 43°C, we can use the following equation:

Q = m × c × ΔT

First, we need to calculate the change in temperature:

ΔT = final temperature - initial temperature

ΔT = 43°C - 70°C

ΔT = -27°C

Note that the change in temperature is negative because the ethanol is cooling down.

Next, we can calculate the heat released:

Q = m × c × ΔT

Q = 60g × 2.44 J/g°C × (-27°C)

Q = -3,950.4 J

If a mixture of gases reaches equilibrium with 0.0113M of H² and CO², the equilibrium concentration of the product is 0.0113 M. Hence, option A is correct.

The equilibrium constant, Keq, is given as:

[tex]\rm K_{eq} = \dfrac{[CO][H_2O]}{ [H_2][CO_2]} \\ \\[/tex]

= 0.16

At equilibrium, let the concentrations of CO, H₂O, and H₂, CO₂  be [CO], [H₂O], [H₂], and [CO₂].

Initial concentration of H₂ and CO₂ = 0.0113

Change in concentration = +X and -X

At equilibrium, for CO = 0-X, H₂O = X,H₂O = 0.0113-X and CO₂=0.0113-X

x² = 0.001207

x = 0.0348 M

Therefore, the equilibrium concentrations of the products are:

[CO] = 0 - x = -0.0348 M

[H₂O] = x = 0.0348 M

[H₂] = 0.0113 - x = 0.0113 - 0.0348 = 0.0225 M

[CO₂] = 0.0113 - x = 0.0113 - 0.0348 = 0.0225 M

Since [CO] is negative, we can conclude that the equilibrium lies to the left, indicating that the reactants are favored over the products.

Answers

Greater than 0 is the change in entropy (AS) when a solid substance decomposes and produces gaseous products. The correct option is B.

The change in entropy (ΔS) is a measure of the degree of randomness or disorder in a system. When a solid substance decomposes and produces gaseous products, the number of particles (molecules or atoms) in the system increases, and the arrangement of the particles becomes more disordered. This results in an increase in entropy, which is greater than 0.

When a solid substance decomposes and produces gaseous products, the change in entropy (ΔS) is greater than 0. This is because the number of particles in the system increases, leading to an increase in disorder or randomness.

The entropy of a system is a measure of the degree of disorder, and it tends to increase in processes that lead to a greater dispersion of energy or matter. In the case of the decomposition of a solid substance into gaseous products, the transition from a more ordered solid state to a more disordered gas state leads to an increase in entropy.

This phenomenon is a manifestation of the second law of thermodynamics, which states that the entropy of a closed system tends to increase over time.

Answers

The uncertainty in the baseball's position is approximately 6.97 × 10⁻³⁶ m.

Using the uncertainty principle, ∆x∆p ≥ h/4π, we can solve for the uncertainty in position:

∆x ≥ h/4π∆p

First, we need to convert the velocity from mph to m/s:

100 mph = 44.7 m/s

Next, we need to convert the momentum from kg · m/s to kg · m/s²:

7.7 kg · m/s = 7.7 N · s

Now we can solve for the uncertainty in position:

∆x ≥ h/4π∆p = (6.626 × 10⁻³⁴ J · s)/(4π × 7.7 N · s)

                     = 6.97 × 10⁻³⁶ m

A flashbulb of volume 1.70 mL contains O2(g) at a pressure of 2.30 atm and a temperature of 29.0 °C. How many grams of O2(g) does the flashbulb contain?

Answers

The flashbulb contains approximately 0.00291 grams of O₂(g).

The ideal gas law relates the pressure (P), volume (V), temperature (T), and amount of gas (n) through the equation PV = nRT, where R is the universal gas constant. Rearranging this equation to solve for n gives n = PV/RT.

To find the amount of O₂(g) in the flashbulb, we first need to convert the volume to liters and the temperature to Kelvin:

V = 1.70 mL = 0.00170 L

T = 29.0 °C + 273.15 = 302.15 K

We can then use the ideal gas law to calculate the amount of O₂(g):

n = PV/RT

n = (2.30 atm)(0.00170 L)/(0.0821 L·atm/mol·K)(302.15 K)

n = 9.10 × 10⁻⁵ mol O₂

Finally, we can convert from moles to grams using the molar mass of O₂:

m = n × M

m = (9.10 × 10⁻⁵ mol)(32.00 g/mol)

m = 0.00291 g O₂

Reactants:

HCN(g): 1 C-N bond (305 kJ/mol) + 1 C-H bond (413 kJ/mol) + 1 N-H bond (391 kJ/mol) = 1109 kJ/mol

2 H2(g): 4 H-H bonds (4 x 432 kJ/mol) = 1728 kJ/mol

If the volume of the container is decreased to 1 liter, what will happen to the equilibrium of the reaction?

Question 16 options:

It will shift left.


It will remain constant.


It will shift right.


It will decrease by half.

Answers

According to Le Chatelier's principle, if a system at equilibrium is subjected to a change, the system will respond in a way that tends to counteract that change and reestablish equilibrium.

In this case, if the volume of the container is decreased from 2 liters to 1 liter, the concentration of all the gases in the container will increase because the same amount of gas is now present in a smaller volume. This will create a shift in the equilibrium of the reaction in the direction that produces fewer moles of gas to counteract the increase in pressure.

Looking at the balanced chemical equation, we can see that the reaction produces 2 moles of SO3 for every 3 moles of reactants. Therefore, the reaction produces fewer moles of gas than the reactants.

So, to counteract the increase in pressure caused by decreasing the volume, the equilibrium of the reaction will shift in the direction that produces fewer moles of gas. This means that the equilibrium will shift to the right, producing more SO3 gas to reduce the concentration of SO2 and O2 gases, and reestablish equilibrium.

Therefore, the correct option is:

C. It will shift right.

where Q is the thermal energy transferred (in Joules), P is the power of the heater (in Watts), and t is the time (in seconds).

We can convert the power from Watts to Joules/second:

30 W = 30 J/s

We can also convert the time from minutes to seconds:

2 minutes = 2 * 60 seconds = 120 seconds

Now we can substitute these values into the formula:

Q = P * t

Q = 30 J/s * 120 s

Q = 3600 J

Therefore, the amount of energy transferred after 2 minutes is 3600 Joules.

The concentration of an aqueous solution of NaCl is 15% by mass. How much NaCl is in a 500 gram sample of the solution?

a. 425 grams
b. 750 grams
c. 75 grams
d. 330 grams

Answers

Answer:

To solve this problem, we can use the definition of percent concentration by mass:

percent concentration = (mass of solute ÷ mass of solution) x 100%

We know that the percent concentration of NaCl in the solution is 15% by mass, and we have a 500 gram sample of the solution. Let's assume that the mass of NaCl in the sample is x grams.

Using the percent concentration formula, we can write:

15% = (x ÷ 500) x 100%

Simplifying this equation, we get:

x = (15 ÷ 100) x 500 = 75 grams

Therefore, there are 75 grams of NaCl in a 500 gram sample of the solution.

The correct answer is c. 75 grams.

a chemistry student collected 0.032l of h2gas at 1.1 atm pressure and 24 C using the following chemical reaction how man grams of magnesium must have reacted.

Mg(s) + HCL (aq) to H2 9g) + MgCL2 (aq)

Answers

In order to calculate the number of grams of magnesium reacted, we must first calculate the moles of hydrogen gas produced. The ideal gas law can be used to calculate the moles of a gas, given the pressure, temperature, and volume of the gas.

The ideal gas law is PV=nRT, where P is pressure, V is volume, n is moles, R is the ideal gas constant, and T is temperature. By calculating the given values, we get 0.032L*1.1atm/24C*0.08206L*atm/mol*K=0.0077 mol.

Since 1 mole of hydrogen gas is produced for every mole of magnesium that reacts, 0.0077 moles of magnesium have reacted.

Finally, to calculate the grams of magnesium, we multiply the moles of magnesium by the molar mass of magnesium, which is 24.31 g/mol. This gives us 0.0077 mol*24.31 g/mol = 0.186 grams of magnesium.

To make a 4 cup pot of green tea, one must heat the water to the boiling point at standard pressure. If the pot contains 680 grams of water, and the temperature at the tap is 20.0°C, how much heat must be absorbed by the water?

Answers

To calculate the amount of heat that must be absorbed by the water, we can use the specific heat capacity of water and the formula:

Q = m * c * deltaT

where Q is the amount of heat absorbed by the water, m is the mass of the water, c is the specific heat capacity of water, and deltaT is the change in temperature.

The specific heat capacity of water is 4.184 J/g°C.

First, we need to calculate the change in temperature of the water. We know that the water needs to be heated to the boiling point, which is 100°C at standard pressure. Therefore, deltaT = 100°C - 20.0°C = 80.0°C.

Next, we can plug in the values we know:

Q = m * c * deltaT
Q = 680 g * 4.184 J/g°C * 80.0°C
Q = 227,584.0 J

Therefore, the amount of heat that must be absorbed by the water to make a 4 cup pot of green tea is 227,584.0 J.

The experiment that will most likely be part of a good demonstration of thermal equilibrium is: D. Bringing together two objects with different temperatures.

Which will be a good example?

Thermal equilibrium is a condition in which the temperature levels of two fluids or substances attain the same temperature. Let us say that a cup of ice-cold water is brought from the freezer to a warm environment.

Thermal equilibrium will be attained when there will be a transfer between the temperature condition of the cup of water and the environment. So, option D is a good example.
