i need help with more questions in the packet heres my question the poisonous gas hydrogen sulfide, H2S, can be neutralized with a base such as sodium hydroxide, NaOH. THE unbalanced equation for this reaction follows:

NaOH(aq)+H2S(g)→Na2S(aq)+H2O(l)
a student who was asked to balance the equation wrote the following Na2OH(aq)+H2S(g)→Na2S(aq)+H3O(l) now i think the student is correct but i don't know and i have to answer my question if the equation is right or not and why.
i have to balance thefollowing equations which is
1.blank C4H10+ blank O2→ blank CO2+ blank H2O NOW I TRIED AND GOT 4C4H10+2O2→1CO2+2H2O
2. IS BLANK C7H6O2+ blank O2→ blank CO2+ blank H20 NOW I TRIED AND GOT 1C7H6O2+2O2→1CO2+1H20
3. BLANK P4O10 + blank H20→ blank H3PO4 I GOT IN THE BLANKS 1,1,1
4. BLANK FeS2+ blank O2→ blank Fe2O3+ blank SO2 I GOT FOR THE BLANKS IS 1,2,2,1
5. MY EQUATION CAME OUT LIKE THIS 1NH3+2O2→1NO+2H2O
6. My equation is this 1Fe+1HCl→2H2+1FeCl2
7. my last equation is this 1Al+2Fe3O4→2Al2O3+1Fe
now i don't know if there right can you please check them and correct them thank you
