Answer 1

Kcl+Agno3------Agcl+Kno3

Answer 2

Reactions and its type are as follows -

a) Chemical reaction of potassium chloride and silver nitrate is -

KCl + AgNO3 --> KNO3 + AgCl.

The insoluble white substance formed is Silver chloride represented by chemical formula AgCl. The reaction is double displacement reaction.

Other compounds are potassium chloride represented by KCl, silver nitrate represented by AgNO3, potassium nitrate  represented by KNO3 and silver chloride represented by AgCl.

b) Chemical reaction of ferrous sulphate decomposition is -

2FeSO4 --> Fe2​O3 + SO2 + SO3.

FeSO4 is chemical formula of ferrous sulphate, Fe2​O3 is chemical formula of ferric oxide, sulphur dioxide and sulphur trioxide is represented by SO2​ and SO3. The reaction is decomposition reaction.
