Warm Up 79

1.A student wants to know what gas is generated when magnesium metal reacts with hydrochloric acid.  Suggest a test that would help them to determine the identity of this gas.

2.This reaction can be represented by the following equation: Mg(s) + 2HCl(aq) → H2(g) + MgCl2(aq).

(a)If 6.00 grams  of magnesium react, how many moles of H2(g) would form?

(b)At STP, what would the volume of this gas be?
