Question

Aluminium reacts with steam to form

• A. Aluminium hydroxide
• B. Aluminium dioxide
• C. Aluminium oxide

Answer 1

The correct option is C

Aluminium oxide

Aluminium

Aluminium is a metal element with the symbol$\left(\mathrm{Al}\right)$ and atomic number$\left(13\right)$.

Aluminium does not react with normal water due to the layer of oxide present on it. When steam is passed over pure aluminium, it reacted and form Aluminium oxide$\left({\mathrm{Al}}_2{\mathrm{O}}_3\right)$ along with Hydrogen gas$\left({\mathrm{H}}_2\right)$ is produced.

Following is the chemical reaction involved in it.
$$\begin{gathered} 2\mathrm{Al}\left(\mathrm{s}\right)+3{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)\to {\mathrm{Al}}_2{\mathrm{O}}_3\left(\mathrm{s}\right)+3{\mathrm{H}}_2\left(\mathrm{g}\right) \\ \left(\mathrm{Aluminium}\right)\left(\mathrm{water}\right)\left(\mathrm{Aluminium}\mathrm{oxide}\right)\left(\mathrm{Hydrogen}\right) \end{gathered}$$

So, Aluminium reacts with steam to form Aluminium oxide.

Therefore, the correct answer is option C Aluminium oxide
