a)a reaction in which a single product is formed from two or more rectants.

b)the reaction mixture becomes warm.

c)an insoluble substance is formed.

d)external surface of the container in which reaction takes place becomes freezing cold.

Answer 1

a) Combination reactants, When 2 or more reactants combine to give out a single product, it is called a combination reaction.

b) Exothermic Reaction: Exothermic reaction is the type of reaction where the mixture of reactants forms a product which releases heat energy.

 c) Precipitation Reaction: Formation of an insoluble salt when two solutions containing soluble salts are combined. The insoluble part is called as a precipitate.

d) Endothermic reactions are the type of reactions which absorb heat energy from surroundings and keep the reaction cold.

Answer 2

Answer:

1. Combination reaction

2.Exothermic reaction

3. Precipitation Reaction

4.Endothermic reaction
