Complete and balance the following equations

NaHCO3(s)+H+(aq)--->
CaO(s)+C(s)--->
C(s)+H2O(g)--->
CuO(s)+CO(g)--->

If possible include charges and physical state.

I THINK ITS

1) The balanced equation is NaHCO3(s) + H+(aq)= Na+(aq) + CO2(g) + H2O(aq). Remember acid + base = salt + water.

2) 2 CaO(s) + 5 C(s) = 2 CaC2(s) + CO2(g)

3)C(s)+H2O(g)=>CO(g)+H2(g

4) CuO (s) + CO (g) Cu (s) + CO2 (g)

I THINK THEY ARE RIGHT.
CHECK WITH SOMEONE ELSE IF ITS TRUE
Those look ok to me.
