Determine the mass of copper that can be obtained from 20 kg of copper (II) oxide by its interaction
Determine the mass of copper that can be obtained from 20 kg of copper (II) oxide by its interaction with hydrogen, if the reaction yield is 75% of the theoretically possible.
Copper oxide is reduced with hydrogen gas. This synthesizes metallic copper and water. The reaction is described by the following chemical reaction equation:
CuO + H2 = Cu + H2O;
Cupric oxide reacts with hydrogen in equal (equivalent) molar amounts. When the reaction proceeds, the same equal chemical amounts of metallic copper and water are synthesized.
Let’s calculate the chemical amount of copper oxide.
To do this, divide the weight of the oxide by the weight of 1 mole of oxide.
M CuO = 64 + 16 = 80 grams / mol;
N CuO = 20,000/80 = 250 mol;
In the course of the reaction, 250 moles of copper oxide can be reduced and 250 moles of copper can be obtained.
Taking into account the yield of 75%, its weight will be:
M Cu = 64 grams / mol;
m Cu = 64 x 250 x 0.75 = 12,000 grams 12 kg;
