Question

Write the chemical equation for the reaction of hot Aluminium with steam.

Answer 1

Metals react with water under different conditions. Some metals react with hot water, some metals react with cold water, some react with steam and some metals do not even react with steam.

Here, Aluminum reacts with steam to produce Hydrogen gas and Aluminum oxide.
