If 72 Grams Of Water And 64 Grams Of Oxygen React, What Mass Of $H_2O_2$ Is Produced?A. 136.06 G

Understanding the Chemical Reaction

In chemistry, balancing chemical equations is a crucial step in understanding the stoichiometry of a reaction. The equation for the decomposition of hydrogen peroxide ($H_2O_2$) into water ($H_2O$) and oxygen ($O_2$) is:

$$2H_2O_2 \rightarrow 2H_2O + O_2$$

This equation shows that 2 moles of hydrogen peroxide produce 2 moles of water and 1 mole of oxygen.

Calculating the Mass of Hydrogen Peroxide Produced

To calculate the mass of hydrogen peroxide produced, we need to know the molar masses of the reactants and products. The molar masses are:

• Hydrogen peroxide ($H_2O_2$): 34.014 g/mol
• Water ($H_2O$): 18.015 g/mol
• Oxygen ($O_2$): 32.000 g/mol

Given that 72 grams of water and 64 grams of oxygen react, we can calculate the number of moles of each reactant using their molar masses.

Calculating the Number of Moles of Reactants

The number of moles of water is:

$$\text{moles of water} = \frac{\text{mass of water}}{\text{molar mass of water}} = \frac{72 \text{ g}}{18.015 \text{ g/mol}} = 4 \text{ mol}$$

The number of moles of oxygen is:

$$\text{moles of oxygen} = \frac{\text{mass of oxygen}}{\text{molar mass of oxygen}} = \frac{64 \text{ g}}{32.000 \text{ g/mol}} = 2 \text{ mol}$$

Determining the Limiting Reactant

To determine the limiting reactant, we need to compare the mole ratio of the reactants to the coefficients in the balanced equation. The balanced equation shows that 2 moles of hydrogen peroxide react with 1 mole of oxygen. Since we have 4 moles of water and 2 moles of oxygen, the mole ratio of water to oxygen is 2:1, which matches the ratio in the balanced equation.

However, we need to consider the stoichiometry of the reaction. The balanced equation shows that 2 moles of hydrogen peroxide produce 2 moles of water and 1 mole of oxygen. Since we have 4 moles of water, we need to calculate the number of moles of hydrogen peroxide that would produce 4 moles of water.

Calculating the Number of Moles of Hydrogen Peroxide

The number of moles of hydrogen peroxide that would produce 4 moles of water is:

$$\text{moles of hydrogen peroxide} = \frac{\text{moles of water}}{2} = \frac{4 \text{ mol}}{2} = 2 \text{ mol}$$

Calculating the Mass of Hydrogen Peroxide Produced

The mass of hydrogen peroxide produced is:

$$\text{mass of hydrogen peroxide} = \text{moles of hydrogen peroxide} \times \text{molar mass of hydrogen peroxide}$$

$$= 68.028 \text{ g}$$
