(e) Indigestion tablets can be made from magnesium oxide. The magnesium oxide
neutralises some of the hydrochloric acid in the stomach.
Complete the word equation for the reaction between magnesium oxide and

All the oxides and hydroxides of metals are basic in nature.

Magnesium oxide is also basic in nature and is a water insoluble base.

When a dilute acid reacts with a base it forms salt and water because the acidity and basicity of the acid and base respectively neutralise each other.This process is known as neutralisation reaction.

When MgO reacts with HCl it forms MgCl2 and water.

In equation form

MgO + 2HCl — MgCl² + H2O

fire could start, buildings collapsing, and ash falling from the sky.

explanation:

this is because the buildings or plants could catch on fire and the buildings would most likely collapse. lastly ash would fall because all the burning would cause ash to fall from the sky.

hope this .
