| Calculate what mass of copper can be obtained if 0.5 mol of copper oxide (11) was heated until the end of the reaction in an excess of hydrogen CuO + H2- Cu + H2O
Divalent copper oxide is reduced with hydrogen gas when heated. 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. In the course of the reaction, the same equal chemical amounts of copper and water are synthesized.
N CuO = 64/80 = 0.5 mol;
Thus, it is necessary to reduce 0.5 mol of copper oxide and synthesize 0.5 mol of copper.
Its weight will be:
M Cu = 64 grams / mol;
m Cu = 64 x 0.5 = 32 grams;
