Na + 02 → Na20
Blank 1:
Blank 2:
Blank 3:

Blank 1:    4

Blank 2:    1

Blank 3:   2

Explanation:

The unbalanced reaction expression is given as:

      Na   +   O₂   →   Na₂O

Now, we use a mathematical approach to balance the reaction given above.

Assign coefficients a , b and c for the blanks:

          aNa   +   bO₂   →   cNa₂O

Conserving Na : a  = 2c

                   O:   2b = c

So, let c  = 1, a  = 2 and b =  

  Multiply through by 2;

          a  = 4,  b  = 1 and c = 2

                    4Na   +   O₂   →   2Na₂O
