When magnesium carbonate, mgco2, reacts with nitric acid, hno3, magnesium nitrate and carbonic acid form. carbonic acid then breaks down into water and carbon dioxide. what two types of reactions take place in this process?

Explanation:

Magnesium carbonate reacts with nitric acid to give magnesium nitrate and carbonic acid.

This type of reaction is termed as double displacement reaction, in which ions of compounds changes their positions with each other to produce the new products.

This type of reaction is termed as decomposition reaction, in which a compound breaks down into two or more smaller compounds.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
