Question

When magnesium carbonate, MgCO2, reacts with nitric acid, HNO3, it forms magnesium nitrate, Mg(NO3)2, and carbonic acid, H2CO3. Carbonic acid then breaks down into water and carbon dioxide. Which two types of reactions take place in this process?

Answer 1

In first one double displacement reaction takes and you can say readaux reaction also is there
Now second is a decomposition reaction

Answer 2

Hey friend!!

Here's ur answer...

__________

1) MgCO2 + HNO3 ----------->Mg(NO3)2 + H2CO3...... This is double displacement reaction..


2) H2CO3 --------->H2O +CO2...... This is decomposition reaction...


_______
