Let a,b,c,d be coefficients in the balanced reaction.

a C₆H₁₂O₆ + b O₂   →   c CO₂ + d H₂O

Count the atoms appearing on either side, and set the counts equal to each other for each element:

C : 6a = c

H : 12a = 2d

O : 6a + 2b = 2c + d

Let a = 1. Then

6a = c   ⇒   c = 6

12a = 2d   ⇒   2d = 12   ⇒   d = 6

6a + 2b = 2c + d   ⇒   6 + 2b = 2•6 + 6   ⇒   2b = 12   ⇒   b = 6

So, the balanced reaction is

1 C₆H₁₂O₆ + 6 O₂   →   6 CO₂ + 6 H₂O

Answer:

a
