1. N2 + 3 H2 = 2 NH3

2. 2 KCIO3 = 2 KCI + 3 O2

3. 2 NaCI + F2 = 2 CI + 2 NaF

4. 2 H2 + O2 = 2 H2O

5. Pb(OH)2 + 2 HCl = 2 H2O + PbCl2

6. 2 AlBr3 + 3 K2SO4 = 6 KBr + Al2(SO4)3

7. CH4 + 2 O2 = CO2 + 2 H2O

8. C3H8 + 5 O2 = 3 CO2 + 4 H2O

9. 2 C8H18 + 25 O2 = 16 CO2 + 18 H2O

10. FeCl3 + 3 NaOH = Fe(OH)3 + 3 NaCl

11. 4 P + 5 O2 = 2 P2O5

12. 2 Na + 2 H2O = 2 NaOH + H2

13. 2 Ag2O = 4 Ag + O2

14. S8 + 12 O2 = 8 SO3

15. 6 CO2 + 6 H2O = C6H12O6 + 6 O2

16. 2 K + MgBr2 = 2 KBr + Mg

17. 2 HCl + CaCO3 = CaCl2 + H2O + CO2

18. HNO3 + NaHCO3 = NaNO3 + H2O + CO2 - already balanced

19. 2 H2O + O2 = 2 H2O2

20. 2 NaNO3 + H2SO4 = Na2SO4 + 2 HNO3

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
