Question

Predict the outcome of this reaction. Balancing doesn't matter.

Mg + H2O -->

Answer 1

MgO + H₂

Step-by-step explanation:

The products of reaction is MgO and hydrogen gas.

This is a single displacement reaction.

In this reaction, the possibility of the reaction is determined by position of the atoms on the activity series.

Mg is higher than H on the activity series, so it is more reactive and it then displaces the hydrogen in water;

Mg + H₂O → MgO + H₂
