How much hydrogen will be released when 100 g of calcium interacts with a sufficient amount of water.

The reaction of calcium with water is described by the following chemical reaction equation:

Ca + 2H2O = Ca (OH) 2 + H2;

One mole of calcium reacts with two moles of water. This forms one mole of hydroxide and one mole of hydrogen.

Let’s find the amount of the substance in 100 grams of calcium.

M Ca = 40 grams / mol;

N Ca = 100/40 = 2.5 mol;

The same amount of hydrogen will be released.

One mole of ideal gas under normal conditions takes a volume of 22.4 liters.

V H2 = 2.5 x 22.4 = 56 liters;
