Hot conc. $${H_2}S{O_4}$$ acts as moderately strong oxidising agent. It oxidises both metals and non-metals. Which of the following elements is oxidised by conc. $${H_2}S{O_4}$$ into two gaseous products?
A.
$$Cu$$
B.
$$S$$
C.
$$C$$
D.
$$Zn$$
Answer :
$$C$$
Solution :
$$C + 2{H_2}S{O_4}\left( {conc.} \right) \to $$ $$C{O_{2\left( g \right)}} + 2S{O_{2\left( g \right)}} + 2{H_2}O$$
