Answer:
(i) Decomposition reaction
In this reaction, calcium carbonate decomposes into calcium oxide and carbon dioxide on heating. This is an important decomposition reaction used in various industries.
(ii) Combination reaction:
Formation of water
In this reaction, two substances hydrogen and oxygen combine to form single substance water, so this is a combination reaction.
Explanation:
We can see from the above examples that a decomposition reaction is opposite of a combination reaction.
