identify each of the following reactions as balanced or unbalanced. ch₄ + 2o₂ → co₂ + 2h₂o: cacl₂ + 2agno₃ → ca(no₃)₂ + 2agcl: 3fe₃o₄ + 4al → 9fe + 4al₂o₃: done
Answer
Answer:
- Balanced
- Balanced
- Unbalanced
Explanation:
Step1: Count atoms in first reaction
On left - 1 C, 4 H, 4 O. On right - 1 C, 4 H, 4 O. So balanced.
Step2: Count atoms in second reaction
On left - 1 Ca, 2 Cl, 2 Ag, 2 N, 6 O. On right - 1 Ca, 2 Cl, 2 Ag, 2 N, 6 O. So balanced.
Step3: Count atoms in third reaction
On left - 9 Fe, 16 O, 4 Al. On right - 9 Fe, 12 O, 8 Al. So unbalanced.
