I have to balance this equation.
pit the numbers 1,2,3 or 4 in the letters A, B AND C.

A = 2, B = 4 and C = 3

Explanation:

The problem here entails balancing of the chemical equations.

 It is given as;

                            A Al₂O₃   →  B Al   +  C O₂

To balance this reaction expression, we are going to use a mathematical approach.

Conserving Al; 2A = B

                    O:  3A  = 2C

let A = 1, B  = 2 and C =

 Now multiply through by 2;

       A = 2, B = 4 and C = 3
