Answer 1

1) 2 C5H5 + Fe → Fe(C5H5)2
- Reaction type: synthesis (combination)

2) Balance: Na(s) + H2O(l) → NaOH(aq) + H2(g)
- Balanced coefficients: 2 Na + 2 H2O → 2 NaOH + 1 H2

3) Which pair would react?
- F2 and KCl

4) Balance: Li(s) + H2O(l) → LiOH(aq) + H2(g)
- Balanced coefficients: 2 Li + 2 H2O → 2 LiOH + 1 H2
