To obtain copper, the following reaction is used: CuO + H2 = Cu + H2O. How much hydrogen

To obtain copper, the following reaction is used: CuO + H2 = Cu + H2O. How much hydrogen is required to produce 128 grams of copper?

Copper oxide is reduced with hydrogen gas. This synthesizes metallic copper and water. This reaction is described by the following equation:

CuO + H2 = Cu + H2O;

Copper oxide reacts with hydrogen gas in equal molar amounts. At the same time, the same equal amounts of copper and water are synthesized.

Let’s find the chemical amount of a substance contained in 128 grams of copper.

M Cu = 64 grams / mol;

N Cu = 128/64 = 2 mol;

The same amount of hydrogen will be required. Let’s calculate the volume of hydrogen. To do this, multiply the molar amount of the substance by the volume of 1 mole of gas (22.4 liters).

N H2 = 2 mol;

V H2 = 2 x 22.4 = 44.8 liters;
