Answer 1

`2\text{ H}_2\text{O}_{2(\text{l})}\text{ }\rightarrow\text{ 2 H}_2\text{O}_{(\text{l\rparen}}\text{ + O}_{2(g)\text{ }}\text{ Descomposition}`
`\text{ K}_2\text{SO}_{4(aq)\text{ }}\text{ + Ba\lparen NO}_3{)}_(2(aq))\text{ }\rightarrow\text{ 2KNO}_(3(aq))\text{ + BaSO}_{4(s)\text{ }}\text{ Metathesis}`
`\text{ PbCl}_(2(aq))\text{ + FeSO}_(4(aq))\text{ }\rightarrow\text{ FeCl}_(2(aq))\text{ + PbSO}_{4(s)\text{ }}\text{ Metathesis}`

A decomposition reaction is a chemical reaction in which one reactant breaks down into two or more products.

A metathesis reaction is a chemical reaction in which the positive ions and negative ions present in the reactants appear to exchange partners.
