Question

# What are the products formed when zinc reacts with steam?A. Zinc hydroxide and oxygenB. Zinc hydroxide and hydrogenC. Zinc oxide and oxygenD. Zinc oxide and hydrogen

Hint: Zinc doesn't react with cold water as it is not reactive enough to react with cold water. To make the reaction of zinc with water proceed further, energy is provided, so it changes the state of cold water to hot steam.

Complete step by step solution:
As stated in the hint zinc doesn't react with cold water, so to make the reaction proceed, we must give some external energy so that the reaction mixture can reach the activation energy barrier and allow the reaction to occur.
- Zinc reacts with steam to give zinc oxide and hydrogen gas.
The reaction can be given as:
${\text{Zinc}} + {\text{Steam}} \to {\text{Zinc oxide + Hydrogen gas}}$
$Z{n_{(s)}} + {H_2}{O_{(g)}} \to Zn{O_{(s)}} + {H_{2(g)}}$
So, we can say that when zinc reacts with steam the products formed are zinc oxide and hydrogen gas.

Therefore, option D is correct.
