Answer:

89.17 u.

Explanation:

he average atomic mass of funnium can be calculated as follows:

Atomic mass = (Relative abundance of first isotope * atomic mass of first isotope) + (Relative abundance of second isotope * atomic mass of second isotope)

Atomic mass = (50.69% * 78.92 u) + (100% - 50.69% * 80.92 u)

Atomic mass = 39.86 u + (49.31 u)

Atomic mass = 89.17 u

So, the average atomic mass of funnium is 89.17 u.

There are 15.6 moles of Li2SO4 in 9.40 x 10^24 formula units after dividing by Avogadro's number.

The given problem involves converting the number of formula units of Li2SO4 to the corresponding number of moles. This conversion requires the knowledge of Avogadro's number, which is the number of particles (atoms, molecules, or ions) in one mole of a substance.

To calculate the number of moles of Li2SO4, we first divide the given number of formula units (9.40 x 10^24) by Avogadro's number (6.022 x 10^23 formula units/mol) to get the number of moles (15.6 mol).

The mole is a unit of measurement used in chemistry to express amounts of a substance. One mole of any substance contains the same number of particles as there are atoms in 12 grams of carbon-12. So, the mass of one mole of a substance is equal to its molecular weight in grams.

In this problem, the mass of Li2SO4 is not given, so we cannot calculate the mass of 15.6 moles of Li2SO4. However, we can say that 15.6 moles of Li2SO4 contain 9.40 x 10^24 formula units.

217.8 mL volume of 0.685 M HCl are required to react completely with 7.47 g of CaCO3.

How to calculate the volume of HCl needed?

The balanced chemical equation for the reaction between HCl and CaCO3 is:

2HCl + CaCO3 → CaCl2 + CO2 + H2O

From the equation, we can see that 2 moles of HCl are required to react with 1 mole of CaCO3. We can use this stoichiometric ratio to calculate the amount of HCl required to react with 7.47 g of CaCO3.

Step 1: Calculate the number of moles of CaCO3.

molar mass of CaCO3 = 40.08 g/mol (Ca) + 12.01 g/mol (C) + 3(16.00 g/mol) (O) = 100.09 g/mol

moles of CaCO3 = mass / molar mass = 7.47 g / 100.09 g/mol = 0.0746 mol

Step 2: Calculate the number of moles of HCl required.

From the balanced equation, we need 2 moles of HCl for every 1 mole of CaCO3.

moles of HCl = 2 x moles of CaCO3 = 2 x 0.0746 mol = 0.1492 mol

Step 3: Calculate the volume of HCl required.

We are given the concentration of HCl as 0.685 M, which means there are 0.685 moles of HCl per liter of solution.

volume of HCl = moles of HCl / concentration of HCl

volume of HCl = 0.1492 mol / 0.685 mol/L = 0.2178 L

To convert the volume to milliliters, we multiply by 1000:

volume of HCl = 0.2178 L x 1000 mL/L = 217.8 mL

Therefore, 217.8 mL volume of 0.685 M HCl are required to react completely with 7.47 g of CaCO3.

Answer:

I'll only answer the first 2 questions because there are too many questions.

1) Hydrogen basically does not really belong to Group 1 or 17 of the periodic table. To be exact, there is to such an extent that some might put it under no groups at all. Hydrogen has 1 electron in its valence shell, similar to elements in group 1. Still, it also has to gain 1 more electron to attain noble gas configuration (2 electrons for 1st shell, 8 electrons for 2nd shell). Hence, no one actually knows what hydrogen should be classified in, hence classifying it into either Group 1, 17 neither or both.

2) Mercury is the only metal that will be in liquid state at room temperature at 1 atm.

The water is colder than the sand because it requires more to change temperature. This is because the Specific heat of water is more than sand.

Specific heat capacity is the amount of thermal energy required to raise the temperature of a substance. Water has a very high specific heat capacity. On the other hand, sand and asphalt have a low specific heat capacity. This means the temperature changes faster.

Sand should heat up and cool faster than water.

This is because water has a higher specific heat than sand, so it takes a lot of heat or energy to raise the temperature of water by 1 degree, whereas it takes relatively little energy to raise the temperature of sand by 1 degree.

And also,

When Brad was swimming in the ocean, he noticed that the sand was hotter than the water in the ocean.

Water is colder than sand because it takes more energy to change its temperature than sand.

This is because the specific heat of water is greater than that of sand. Due to this, sand cools and heats up faster than water.

The given equation is 2NOBr(g) -> 2NO(g) + Br2(g)

This is a decomposition reaction, which means that the total number of moles of gas will increase.

From the balanced chemical equation, we can see that 2 moles of gas are produced for every 2 moles of NOBr consumed. Therefore, the number of moles of gas will double when the reaction is complete.

Let x be the final pressure of the gas mixture in torrs.

Initially, the pressure of NOBr is 400 torrs, and the initial pressure of NO and Br2 is 0 torrs.

When the reaction is complete, 2 moles of gas will be present for every 1 mole of NOBr initially present. Therefore, the final pressure of the gas mixture is:

x = (2 moles of NO + 1 mole of Br2) / (2 moles of NOBr) x 400 torrs

x = (2 + 1/2) x 400 torrs

The empirical formula of a compound can be determined from the results of a combustion analysis. The empirical formula represents the simplest whole-number ratio of atoms in the molecule.

Here's how you can determine the empirical formula of the hydrocarbon based on the given information:

Determine the number of moles of CO2 produced:

moles = mass / molar mass

moles = [tex]22.0 g / (44.0 g/mol) = 0.5 mol[/tex]

Determine the number of moles of carbon in the sample:

moles of carbon = moles of CO2 produced / ratio of C:CO2

moles of carbon = [tex]0.5 mol / 1 : 1 = 0.5 mol[/tex]

Determine the number of moles of hydrogen in the sample:

moles of hydrogen = moles of CO2 produced / ratio of H:CO2

moles of hydrogen = [tex]0.5 mol / 1 : 2 = 0.25 mol[/tex]

Express the number of moles of each element as a whole number ratio:

moles of carbon / smallest number of moles = [tex]0.5 mol / 0.5 mol = 1[/tex]

moles of hydrogen / smallest number of moles =[tex]0.25 mol / 0.25 mol = 1[/tex]

So, the empirical formula of the hydrocarbon is CH, indicating that for every one carbon atom, there is one hydrogen atom in the molecule.

To find the molecular formula, you can use the empirical formula and the molar mass of the compound. The molecular formula is a multiple of the empirical formula and can be determined by dividing the molar mass of the compound by the empirical formula weight:

Empirical formula weight =[tex]12.0 g/mol + 1.0 g/mol = 13.0 g/mol[/tex]

Molecular formula multiple = molar mass / empirical formula weight

Molecular formula multiple = [tex]70 g/mol / 13.0 g/mol = 5.3846[/tex]

The molecular formula multiple is not a whole number, so we round up to the nearest whole number, which is 6. The molecular formula of the hydrocarbon is therefore 6 times the empirical formula, or C6H6.

The work done on the gas during the compression process is 0.0418 kJ/K.

The work done on the gas during a compression process can be calculated using the equation:

w = -P * (Vf - Vi)

where P is the external pressure, Vf is the final volume, and Vi is the initial volume. The negative sign indicates that work is done on the gas.

Using the given values, we have:

w = -3.00 atm * (2.00 L - 6.00 L)

The volume units need to be converted to liters:

w = -3.00 atm * (2.00 L - 6.00 L) = -3.00 atm * (-4.00 L) = 12.00 L * atm

Next, the pressure unit must be converted to pascals:

w = 12.00 L * atm * (1.00 atm) = 12.00 L * 1.01325 * 10^5 Pa = 12.16 kJ

Finally, the work done must be divided by the temperature to get the work done per kelvin:

w / T = 12.16 kJ / (292.0 K) = 0.0418 kJ/K

So the work done on the gas during the compression process is 0.0418 kJ/K.

Explanation:

To calculate the volume of a gas mixture, you can use the Ideal Gas Law, which states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.

First, we need to calculate the number of moles of Ne and Ar.

n(Ne) = 15.2 g / 20.18 g/mol = 0.755 mol

n(Ar) = 34.8 g / 39.95 g/mol = 0.871 mol

Next, we can use the total number of moles to find the volume of the mixture:

n(total) = n(Ne) + n(Ar) = 0.755 + 0.871 = 1.626 mol

V = nRT / P = (1.626 mol)(8.31 J/mol K)(26.7 + 273.15 K) / (7.24 bar) = 0.0254 m^3, or 25.4 liters.

So the volume occupied by the mixture of 15.2g Ne(g) and 34.8g Ar(g) at 7.24 bar pressure and 26.7°C is approximately 25.4 liters.

Answer:

0.54 M NaCl.

Explanation:

The final concentration of the mixture can be found using the formula for the dilution of a solution:

C1 * V1 + C2 * V2 = C_final * (V1 + V2)

where C1 and C2 are the initial concentrations of the two solutions, V1 and V2 are their volumes, and C_final is the final concentration of the mixture. Plugging in the given values, we get:

0.680 M * 279 mL + 0.450 M * 462 mL = C_final * (279 mL + 462 mL)

0.680 M * 279 mL + 0.450 M * 462 mL = C_final * 741 mL

0.680 M * 279 mL + 0.450 M * 462 mL = C_final * 0.741 L

Converting volumes to liters:

0.680 M * 0.279 L + 0.450 M * 0.462 L = C_final * 0.741 L

0.680 M * 0.279 L + 0.450 M * 0.462 L = C_final * 0.741 L

0.190982 + 0.209719 = C_final * 0.741 L

0.400701 = C_final * 0.741 L

Dividing both sides by 0.741 L:

0.400701 / 0.741 L = C_final

So, the final concentration of the mixture is 0.54 M NaCl.

The final answer is: T = 401 K

Celsius temperature scale is a metric temperature scale that is commonly used in most countries around the world. It is based on the Celsius temperature scale, which is defined by the melting and boiling points of water at standard atmospheric pressure.

How to convert the temperature from Celsius to Kelvin (the SI unit of temperature)

First we simply add 273.15 to the Celsius temperature:

T(K) = T(°C) + 273.15

In this case, T = 128. °C. Substituting this into the above equation, we get:

T(K) = 128. °C + 273.15 = 401.15 K

Therefore, the temperature in SI units is 401.15 K.

Since the given temperature has three significant digits, the converted temperature should also have three significant digits.
