When 32.0 g of H2 and 12.0 g of O2 are mixed and allowed to react to form water, the end result will be 44.0 g of H2O.

This is because the equation for the reaction is 2H2 + O2 = 2H2O, so for every two grams of H2 that are present, one gram of O2 must be present to balance the equation. Therefore, 32.0 g of H2 and 12.0 g of O2 will result in 44.0 g of H2O.
To solve this problem, first calculate the amount of H2 and O2 needed to create the desired amount of H2O. Using the equation, the ratio of H2 to O2 is 2:1, so the total amount of O2 needed to react with the given amount of H2 is 16.0 g (32.0 g of H2 divided by 2). Next, calculate the amount of H2O that will be produced. To do this, use the equation 2H2 + O2 = 2H2O, so the total amount of H2O produced is twice the amount of H2 and O2, or 44.0 g (32.0 g of H2 + 16.0 g of O2 = 48.0 g, then divided by 2 = 24.0 g).

Answer: The volume of gas released from the tank at the peak of Mt. Everest is 37.83 liters.

Explanation: To solve this problem, we can use the general gas law equation:

PV = nRT

where P is pressure, V is volume, n is the number of moles of gas, R is the gas constant, and T is temperature (in Kelvin).

We can rearrange this equation to solve for volume:

V = nRT/P

We are given the internal gas pressure of the tank (P) and the volume of the tank (10.0 L). We need to find the volume of gas released from the tank (V). We also know that the temperature and number of moles of gas are constant (assuming no leaks or temperature changes during the climb).

To find the volume of gas released at the peak of Mt. Everest (150 mm Hg), we can use the following steps:

Convert the internal gas pressure of the tank to atm:

3.04 x 10¹ mm Hg x (1 atm / 760 mm Hg) = 0.004 atm

Convert the peak pressure to atm:

150 mm Hg x (1 atm / 760 mm Hg) = 0.197 atm

Plug in the known values to the equation:

V = nRT/P

V = nRT / (0.197 atm)

Solve for V:

V = (nRT) / (0.197 atm)

We can assume that the number of moles of gas, n, and the temperature, T, are constant. R is also a constant (0.08206 L atm / mol K).

So we can simplify the equation to:

V = constant / P

V = k / 0.197

where k is a constant. We can solve for k by using the initial conditions:

10.0 L = k / 0.004

k = 0.04 L atm

Now we can use this value of k to find the volume of gas released at the peak of Mt. Everest:

V = k / 0.197

V = 0.04 L atm / 0.197

V = 0.203 L

But this is the volume of gas at standard conditions (0°C and 1 atm). We need to correct for the temperature and pressure at the peak. To do this, we can use the following equation:

(P1 V1) / (n1 T1) = (P2 V2) / (n2 T2)

where the subscripts 1 and 2 refer to the initial and final states of the gas.

We can assume that n and V are constant, so this equation simplifies to:

P1 / T1 = P2 / T2

We can solve for T2:

T2 = (P2 T1) / P1

T1 is the initial temperature of the gas (room temperature, about 20°C or 293 K). P1 is the initial pressure of the gas (0.004 atm). P2 is the final pressure of the gas (0.197 atm).

T2 = (0.197 atm x 293 K) / 0.004 atm

T2 = 14,502 K

This temperature is obviously not physically realistic, but it shows that the volume of gas is greatly affected by the low pressure and temperature at the peak of Mt. Everest. To correct for this, we can assume that the gas behaves ideally and use the ideal gas law equation:

PV = nRT

We can solve for V:

V = (P2 V1 T1) / (P1 T2)

V = (0.197 atm x 10.0 L x 293 K) / (0.004 atm x 14,502 K)

V = 37.83 L

So the volume of gas released from the tank at the peak of Mt. Everest is about 38 liters.

Yes, it is possible to determine the amount of energy released in a combustion reaction. Energy released as the products form is called the heat of reaction or enthalpy change (ΔHrxn) and can be calculated using  balanced chemical equation and the standard enthalpies of formation (ΔHf) of reactants and products.

The standard enthalpy of formation of an element in its standard state is defined as zero.

ΔHrxn = ΣnΔHf(products) - ΣmΔHf(reactants)

ΔHf(products) is the standard enthalpy of formation of each product, n is the stoichiometric coefficient of each product, ΔHf(reactants) is standard enthalpy of formation of each reactant, and m is the stoichiometric coefficient of each reactant.

CH4(g) + 2O2(g) → CO2(g) + 2H2O(g)

The standard enthalpies of formation of methane, oxygen, carbon dioxide, and water are -74.8 kJ/mol, 0 kJ/mol, -393.5 kJ/mol, and -285.8 kJ/mol, respectively.

ΔHrxn = [ΔHf(CO2) + 2ΔHf(H2O)] - [ΔHf(CH4) + 2ΔHf(O2)]

= [(-393.5 kJ/mol) + 2(-285.8 kJ/mol)] - [(-74.8 kJ/mol) + 2(0 kJ/mol)]

To get a 30% solution of sulfuric acid, 4 oz of a 35% solution of sulfuric acid (and distilled water) must be mixed with 20 oz of a 20% solution of sulfuric acid.

A solution is a homogeneous mixture of two or more substances. For instance, two or more gases, or a gas and a solid, or a liquid and a solid, or two or more liquids could be mixed to create a solution.

First, determine the volume of sulfuric acid in each solution, then combine them to obtain the total amount of sulfuric acid. Solve the equation based on the sulfuric acid content in the final solution.

The volume of sulfuric acid in 35% solution is:

35% = 35/100

      = 0.35

V1 = volume of 35% solution of sulfuric acid and distilled water

V1 = 0.35 x V1

Suppose V2 is the volume of 20% solution of sulfuric acid, then

20% = 20/100

       = 0.2

V2 = volume of 20% solution of sulfuric acid

V2 = 0.2 x 20 oz

    = 4 oz

Let's combine the two solutions.

Total volume is (V1 + V2) ounces,

and the amount of sulfuric acid is 0.35V1 + 0.2V2 ounces.

The volume of sulfuric acid in the final mixture is:

30% = 30/100

        = 0.3

V1 + V2 = total volume

0.35V1 + 0.2V2 = total sulfuric acid volume

(0.3 x (V1 + V2)) = 0.35V1 + 0.2V2

V1 + V2 = 40

V1 = 4 oz

Substitute the value of V1 in the equation

V1 + V2 = 40(4 oz) + V2

             = 40 V2

              = 36 oz

To solve this problem, we can use the concept of the concentration of a solution, which is given by the amount of solute (in this case sulfuric acid) divided by the total amount of solution (sulfuric acid and water) multiplied by 100.

Or

Let x be the number of ounces of the 35% solution of sulfuric acid needed to make a 30% solution. We know that we have 20 ounces of a 20% solution. We can set up an equation based on the concentration of the sulfuric acid in the two solutions:

(0.35x + 0.20(20)) / (x + 20) = 0.30

Simplifying this equation, we get:

0.35x + 4 = 0.30x + 6

0.05x = 2

x = 40

Therefore, we need 40 ounces of the 35% solution of sulfuric acid to mix with the 20 ounces of the 20% solution to obtain a 30% solution.

To find the ratio of the anhydrous compound to water, we need to divide each of these values by the smallest one, which is 0.5057 mol:

Mn: 0.5057 / 0.5057 = 1 mol

Cl: 1.0096 / 0.5057 = 1.996 mol

H2O: 2.0228 / 0.5057 = 4 mol

Therefore, the formula of the hydrate is MnCl2·4H2O.

b. The name of the hydrate can be determined by adding the prefix "tetra" to the name of the anhydrous compound (since there are four moles of water) and adding the word "hydrate" to the end. So the name of this hydrate is tetrahydrate manganese (II) chloride.
