AUnbalanced in oxygen atoms
BBalanced, but coefficients can reduce
CUnbalanced in hydrogen atoms
DBalanced with least coefficients
Answer & Solution
Correct answer: B. Balanced, but coefficients can reduce
Both sides have eight hydrogen atoms and four oxygen atoms, but all coefficients can be divided by two.
