Question

define precipitation reaction and exothermic reaction. write balanced equation for each type of reaction​

Answer 1

Answer:

A precipitation reaction is a kind of chemical reaction in which two soluble salts in a fluid solution mixes and one of the items is an insoluble salt called a precipitate.

AgNO3(aq) + KCl(aq) → AgCl(s) + KNO3(aq)

An exothermic reaction is a reaction in which energy is released in the form of light or heat.

4Fe  + 3O2  → 2Fe2O3  ΔH⚬ = - 1648 kJ/mol
