Question

When the following equation is balanced the coefficients are ______.

A. 2, 3, 4, 4
B. 2, 25, 16, 18
C. 1, 4, 8, 9
D. 2, 12, 8, 9
E. 4, 4, 32, 36

Answer 1

The coefficients that balance the equation are 2, 12, 8, 9.

Step-by-step explanation:

The equation 2H2 + O2 → 2H₂O is balanced, but we can also write it as 4H₂ + 2O₂ → 4H₂O. The ratio of the coefficients is 4:2:4, which reduces to 2:1:2. Another balanced equation would be 22H2 + 11O2 → 22H₂O, where the coefficients are multiples of 2.
