one reactant and two products

one reactant and one product

two reactants and two products

two reactants and one product

Answer 1

2 reactants and 2 products. All are compounds

Step-by-step explanation:

Answer 2

Answer : The correct option is, two reactants and two products.

Explanation :

Double replacement reaction : It is a type of chemical reaction in which a positive cation and a negative anion of two reactants exchange their places to form two new products.

It is represented as,

`XY+AB\rightarrow XB+AY`

(X and A are the cations, Y and B are the anions)

For example : Barium chloride react with magnesium sulfate to give barium sulfate and magnesium chloride as a product.

The balanced chemical reaction will be:

`BaCl_2+MgSO_4\rightarrow MgCl_2+BaSO_4`

From this we conclude that, there are two reactants and two products are present in a double-replacement reaction.

Hence, the correct option is, two reactants and two products.
