How much hydrogen can be released during the interaction of hydrochloric acid with calcium 16?

1. We make a chemical equation, not forgetting to put down the coefficients:

Ca + 2HCl = CACl2 + H2.

2. Let’s find the amount of calcium substance:

n (Ca) = m / M = 16/40 = 0.4 mol.

3. From the equation you can see:

n (Ca) = n (H2) = 0.4 mol.

4. Let’s find the volume of hydrogen:

V (H2) = n * Vm = 0.4 * 22.4 = 8.96 liters.

Answer: V (H2) = 8.96 liters.
