Question

Mg and Mn react with 5% HNO, to form $H_2$(g). [True/ False]

✓

Answer

True.
Explanation:
Nitric acid ($HNO_3$) is a strong oxidising agent. So as soon as hydrogen gas is formed in the reaction it gets oxidised into $HNO_3$ by Nitric acid and it (nitric acid) itself gets reduced into $NO_2, NO_2$ or NO.
