How much oxygen is required to completely burn 3 moles of copper?
| September 27, 2021 | education
The combustion reaction of copper is described by the following chemical reaction equation:
Cu + ½ O2 = CuO;
In accordance with the coefficients of the equation, half a mole of oxygen reacts with one mole of copper and one mole of copper oxide is formed. This is due to the fact that there are two oxygen atoms in the oxygen molecule, and one oxygen atom in the copper oxide molecule.
Therefore, for the combustion of 3 mol of copper, 3/2 = 1.5 mol of oxygen is required.
