Question

Example of decomposition reaction calcium carbonate

Answer 1

Explanation:

Calcium carbonate will decompose to form carbon dioxide and calcium oxide.

Carbonate compounds will decompose when heated.

Here is the balanced equation for this reaction:

Calcium carbonate has a 1:1 ratio because calcium forms a +2 ion and carbonate has a -2 charge.

Calcium oxide must have the formula CaO because calcium forms an ion with a +2 charge and oxide has a -2 charge.

Answer 2

Answer:

when a single reactant decompose into 2 or more products.. this reaction is called as decomposition reaction.

for example-

 CaCO3----------> CaO + CO2
