Question

12 g Mg (at mass 24) react with dilute mineral acid to produce maximum hydrogen equal to
(1) 0.5 mol
(2) 1.5 mol
(3) 1.5 g
(4) 0.5 g
can anyone explain with details!!!!! ​

Answer 1

Answer:

0.5 mol

Explanation:

Mg + 2HCl = MgCl2+ H2

1mol of Mg produce 1 mol of H2

no.of molof Mg = 12/24= 0.5

hence,

0.5mol Mg will produce 0.5mol of H2
