Blank 1:
Blank 2:
Blank 3:

Answer 1

Blank 1: 4

Blank 2: 1

Blank 3: 2

Step-by-step 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 =
`(1)/(2)`

Multiply through by 2;

a = 4, b = 1 and c = 2

4Na + O₂ → 2Na₂O
