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? A) synthesis and decomposition B) single-replacement and combustion C) double-replacement and decomposition D) double-replacement and combustion

Respuesta :

Answer:

C) double-replacement and decomposition.

Explanation:

Double replacement reaction or double displacement reaction is defined as a chemical process involving the exchange of bonds between two non-reacting chemical species resulting in the creation of products with bonding affiliations.

Equation of the reaction

Mg(NO3)2 + H2CO3 --> MgCO3 + 2HNO3
