Question

identifying reaction types & balancing equations
step 2: balance the following chemical equations:

1. n₂ + 3 h₂ → 2 nh₃
2. kclo₃ → 2 kcl + 3 o₂
3. nacl + f₂ → naf + cl₂
4. h₂ + o₂ → h₂o
5. agno₃ + mgcl₂ → agcl + mg(no₃)₂
6. albr₃ + k₂so₄ → kbr + al₂(so₄)₃
7. ch₄ + o₂ → co₂ + h₂o
8. c₃h₈ + o₂ → co₂ + h₂o
9. fecl₃ + naoh → fe(oh)₃ + nacl
10. p + o₂ → p₂o₅
11. na + h₂o → naoh + h₂
12. ag₂o → ag + o₂
13. co₂ + h₂o → c₆h₁₂o₆ + o₂
14. k + mgbr₂ → kbr + mg
15. hno₃(aq) + ba(oh)₂(aq) → ba(no₃)₂(aq) + h₂o(l)
16. c₅h₁₂(g) + o₂(g) → co₂(g) + h₂o(g)
17. al(s) + fe₂o₃(aq) → al₂o₃(aq) + fe(s)
18. al(s) + o₂(g) → al₂o₃(s)
