Question

$Zn+H_{2}S{O}_4\to A$
If we bring a burning splinter near the gas produced in the given reaction,it burns with a pop sound. The gas A is:

• A. $O_2$
• B. $N_2$
• C. $H_2$
• D. $C{O}_2$

Answer 1

The correct option is C $H_2$

Zinc with $+2$ valency reacts with sulfate ion (valency $-2$) and forms zinc sulfate releasing hydrogen gas giving the pop sound when a burning splinter is brought nearby.
