Answer 1

A₃B.

Step-by-step explanation:

3 AA + BB → 2 products.

• Any chemical reaction should obey the law of conservation of mass that the no. of reactants atoms is equal to the no. of products atoms.

• Herein, 6 atoms of A react with 2 atoms of B.

• So, the product should contain 6 atoms of A and 2 atoms of B.

• The reaction produces 2 units of the product, so the product unit must contain 3 atoms of A and 1 atom of B.

• Thus, the product unit is A₃B.

• The reaction is:

3AA + BB → 2A₃B.
