What mass of calcium oxide can be obtained by complete combustion of 16 g of calcium?
| January 4, 2021 | education
The reaction of calcium with oxygen takes place according to the following chemical reaction equation:
Ca +1/2 O2 = CaO;
For the oxidation of 1 mol of calcium, 0.5 mol of oxygen is required. This forms 1 mol of calcium oxide.
Let’s find the amount of calcium.
M Ca = 40 grams / mol;
N Ca = 16/40 = 0.4 mol;
We calculate the mass of 0.4 mol of calcium oxide.
M CaO = 40 + 16 = 56 grams / mol;
m CaO = 56 x 0.4 = 22.4 grams
