1.	Define the term decomposition reaction. Give one example each for thermal decomposition and electrolytic decomposition reaction.
Answer» Solution :A chemical reaction in which a single compound or REACTANT breaks down into two or more simpler products is called chemical DECOMPOSITION reaction. Example : Decomposition reaction carried out by heating is called thermal decomposition. Decomposition of calcium CARBONATE : `CaCO_(3)(s)overset("heat")toCaO(s)+CO_(2)(g)` Example : When a decomposition reaction takes place with the help of electric current, the PROCESS is called electrolysis. Electrolytic decomposition of water : `2H_(2)O(L)overset("electric current")to2H_(2)(g)+O_(2)(g)`
