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

C.) double-replacement and decomposition

Explanation:

: is a double displacement reaction in which ion exchange takes place.

is a decomposition reaction as one reactant breaks down to give two or more than two products.

Synthesis reaction involve two or more than two reactants to give single product.

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.

Combustion involves reaction of hydrocarbon with oxygen to form carbon dioxide and water.

-be a crystalline solid

- be soluble in water

-conduct electricity

hope this : )
