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?
1.) synthesis and decomposition
2.) single-replacement and combustion
3.) double-replacement and decomposition
4.) double-replacement and combustion

I'm a geologist, not a chemist, but the Mg replaces the hydrogen in nitric acid, and the H replaces the Mg in the carbonate. Since this involves two replacements and decomposition of the carbonateI would vote for #3.
Magnesium carbonate, by the way, is MgCO3.

i think of your question's been responded already, yet hi, from my attitude, i think of redox reactions ore double displacement reactions are the finest for sophistication initiatives! :) solid success...
