Chemistry Balancing Equations

Can you please tell me if these are correct?

1. Sodium Hydrogen Sulfite reacts with hydrochloric acid to produce sulfur dioxide gas, water and sodium chloride

NaHSO3 + HCl -----> SO2 + H2O + NaCl

2. Sodium nitrate reacts with hydrochloric acid to produce nitrogen monoxide gas, water sodium chloride, and sodium nitrate

NaNO3 + HCl -----> N2O + H2O + NaCl + NaNO3

3. Nitro monoxide gas from the above reaction reacts with oxygen gas in the air to produce nitrogen dioxide gas.

N2O + O2 -----> NO2

4. Sodium hydrogen carbonate reacts with hydrochloric acid to produce carbon dioxide gas, water and sodium chloride

NaHCO3 + HCl -----> CO2 + H2O + NaCl

5. Hydrogen peroxide reacts with the permanganate ion and hydrogen iron to produce oxygen gas, manganese (II)ion, and water

H2O2 + MnO4- + Fe ------> O2 + Mn + Fe(II) + H2O

6. Chlorine gas, water and sodium chloride are produced when hydrochloric acid is added to sodium hydrochloride, NAOCl

HCl + NaOCl -----> Cl2(g) + NaCl

7. Sodium hydroxide reacts with ammonium chloride to produce ammonia gas, water and sodium chloride.

NaOH + NH4Cl ------> NH3 + H2O + NaCl
