How much oxygen is necessary to take to get calcium oxide with an amount of 0.3 mol.
| May 1, 2021 | education
The combustion reaction of calcium is described by the following chemical reaction equation.
Ca + ½ O2 = CaO;
When one mole of calcium is burned, one mole of its oxide is formed. This requires half a mole of oxygen. This is due to the fact that the oxide molecule has one oxygen atom, and the oxygen molecule has two oxygen atoms.
Therefore, in order to obtain 0.3 mol of calcium oxide, it is necessary to take 0.3 / 2 = 0.15 mol of oxygen.
