Question 79
Easy

This question is about the rate of reaction between magnesium carbonate and dilute nitric acid.

The word equation for this reaction is:

magnesium carbonate+nitric acid→magnesium nitrate+water+carbon dioxide \text{magnesium carbonate} + \text{nitric acid} \rightarrow \text{magnesium nitrate} + \text{water} + \text{carbon dioxide} magnesium carbonate+nitric acid→magnesium nitrate+water+carbon dioxide

Which of the following is the correct chemical formula for magnesium carbonate?

MgCO2\text{MgCO}_2MgCO2​

MgCO3\text{MgCO}_3MgCO3​

Mg(CO)3\text{Mg(CO)}_3Mg(CO)3​

Mg(CO3)2\text{Mg(CO}_3)_2Mg(CO3​)2​
