Question

6 gram magnesium react with excess of an acid the amount of hydrogen produce would be

Answer 1

Answer:

1g of H2 will be produced.

Explanation:

Mg + H2SO4 ------> MgSO4 + H2

Mg + 2 HCl -------> MgCl2 + H2

If the acid you specified is any of these, this will be true. Mostly one mole of magnesium reacts with acid to produce one mole of hydrogen gas. Based on this assumption,

12g of Mg produce 2g of H2

6g of Mg produce (6×2)/12= 1

1g of H2 will be produced.
