The chemical equation shows the production of magnesium chloride.
Norma-Jean [14]

Answer:

1 gram of H2 will be produced from 12 grams of Mg.

Explanation:

According to Stoichiometry, 0.5 moles of Mg are present. 1 mole of Mg produces 1 mole of H2, so 0.5 moles of Mg will produce 0.5 moles of H2. Multiplying molar mass of H2 i.e. 2 gram/mole with 0.5 moles, we can find the mass of H2 in grams which is 1 gram.
