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.

Julian put a heater with a power of 30 W into a block of copper and recorded the temperature of the block every minute for ten minutes. His results are below. How much energy had been transferred after 2 minutes?

Answers

The amount of energy transferred after 2 minutes is 3600 Joules.

We can use the formula for thermal energy to calculate the amount of energy transferred after 2 minutes:

Q = P * t

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.

A 0.17−kg baseball thrown at 100 mph has a momentum of 7.7 kg · m/s. If the uncertainty in measuring the mass is 1.0 × 10−7 of the mass, calculate the uncertainty in the baseball's position.

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

As a result, the uncertainty in baseball's location is around 6.97 × 10⁻³⁶ m. This value is incredibly small and practically impossible to measure, indicating that the uncertainty in measuring the mass has no significant effect on the uncertainty in position.

Combustion engines became common in the mid-1800s when people began to use them to power ships, trains, and machinery in factories. Combustion engines add carbon dioxide to the air, and as a result, carbon dioxide in the atmosphere increased quickly. How did this change the total amount of energy in the Earth system, and how did this change happen? How did this affect global average temperature?

Answers

The increased carbon dioxide levels from combustion engines caused a change in the Earth's energy balance. The additional carbon dioxide in the atmosphere allowed less radiation to escape into space, leading to a net increase in energy retained by the Earth.

This increase in energy is known as the enhanced greenhouse effect, which caused the Earth's average temperature to rise. This phenomenon is known as global warming. The rise in temperature has had numerous impacts on the Earth's climate, including more frequent heatwaves, melting ice caps, rising sea levels, and changes in precipitation patterns.

The enthalpy change for the given reaction is 1344 kJ/mol.

First, we need to write the balanced chemical equation for the given reaction:

HCN(g) + 2 H2(g) → CH3NH2(g)

To calculate the enthalpy change (ΔH) for this reaction, we need to subtract the total energy of the reactants from the total energy of the products. We can do this by calculating the energy required to break the bonds in the reactants and the energy released when new bonds are formed in the products.

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

Total energy of reactants: 1109 kJ/mol + 1728 kJ/mol = 2837 kJ/mol

Products:

CH3NH2(g): 1 C-H bond (413 kJ/mol) + 3 C-N bonds (3 x 305 kJ/mol) + 7 H-H bonds (7 x 432 kJ/mol) = 4181 kJ/mol

Total energy of products: 4181 kJ/mol

ΔH = (total energy of products) - (total energy of reactants)

ΔH = 4181 kJ/mol - 2837 kJ/mol

ΔH = 1344 kJ/mol

20. At its closest approach, Mars is 56 million km from Earth. How long would a radio message from a space probe on Mars take to reach Earth when the planets are at this distance?​

Answers

Answer:

The time it takes for a radio message to travel from a space probe on Mars to Earth when the planets are at a distance of 56 million km can be calculated using the speed of light which is about 299,792,458 meters per second.

To convert the distance from kilometers to meters, we multiply 56 million km by 1000 to get 56 x 10^6 km = 5.6 x 10^10 m.

The time it takes for a radio signal to travel from Mars to Earth is:

time = distance/speed

time = 5.6 x 10^10 m / 299,792,458 m/s

time = 187 seconds

Therefore, a radio message from a space probe on Mars would take about 187 seconds, or just over 3 minutes, to reach Earth when the planets are at a distance of 56 million km.

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).

a. combustible reaction
b. spontaneous reaction
c. endothermic reaction
d. exothermic reaction

Answers

Answer: c. endothermic reaction.

Explanation: In an endothermic reaction, energy is absorbed or required to break the bonds in the reactants. This means that more energy is required to break the bonds than is released by the formation of new bonds in the products, resulting in a net absorption of energy. In this case, the amount of energy required to break the bonds (1254 kJ) is higher than the energy produced by breaking the bonds (1001 kJ), indicating that the reaction requires an input of energy and is therefore endothermic.

Answer:

c. endothermic reaction

Explanation:

The given information states that the amount of energy required to break the bonds of the covalent compound is 1254 kJ, and the energy produced as a result of breaking the bonds is 1001 kJ.

In an endothermic reaction, the energy required to break the bonds is greater than the energy released or produced. This means that more energy is absorbed from the surroundings than is released during the reaction. In this case, since the energy required to break the bonds (1254 kJ) is greater than the energy produced (1001 kJ), it indicates that the reaction requires an input of energy from the surroundings, making it an endothermic reaction.
