In a chemical reaction, sodium sulphate and barium chloride are mixed to form barium sulphate(a precipitate)and sodium chloride. (i)What are the reactants in the above reaction? (ii)What are the products?

i) The reactants are sodium sulphate and barium chloride

ii) The products are barium sulphate and sodium chloride.

Explanation:

In chemistry, a chemical reaction occurs when one or more chemical substances usually referred to as REACTANTS undergoes some processes and is converted to one or more different substances known as PRODUCTS.

From the question:

Na2SO4 + BaCl2 ⟶ 2NaCl + BaSO4

​The above balanced equation represents the chemical reaction between sodium sulphate and barium chloride. Both are the reactants because they where the substances that passed through a process ( this involves the breaking of bond that held them together).

The PRODUCTS are barium sulphate and sodium chloride because they are the substances that presented at the end of the chemical reaction.
