I really need help with balancing these equations: Can you check if my answer are correct? Please

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

4NaNO2 + 2HCL = N2O + H2O + 2NaCl + 2 NaNO3

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

2N2O + 3O2 = 4NO2

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

I need help with this one please tell me the chemical equation and if u can balance it please

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

2HCl + NaOCl = Cl2 + H20 + NaCl

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

NaOH + NH4Cl = NH3 + H2O + NaCl

I think it is correct

Ag HNO3

I don't no

Let's go through each equation and check if they are correctly balanced:

1. Sodium Hydrogen Sulfite reacts with hydrochloric acid to produce sulfur dioxide gas, water, and sodium chloride:
NaHSO3 + HCl → SO2 + H2O + NaCl

This equation is correctly balanced.

2. Sodium nitrate reacts with hydrochloric acid to produce nitrogen monoxide gas, water, sodium chloride, and sodium nitrate:
4NaNO2 + 2HCl → N2O + H2O + 2NaCl + 2NaNO3

This equation is also correctly balanced.

3. Nitro monoxide gas from the above reaction reacts with oxygen gas in the air to produce nitrogen dioxide gas:
2N2O + 3O2 → 4NO2

This equation is correctly balanced.

4. Sodium hydrogen carbonate reacts with hydrochloric acid to produce carbon dioxide gas, water, and sodium chloride:
NaHCO3 + HCl → CO2 + H2O + NaCl

This equation is correctly balanced.

5. Hydrogen peroxide reacts with the permanganate ion and hydrogen iron to produce oxygen gas, manganese (II) ion, and water:
H2O2 + MnO4- + Fe2+ → O2 + Mn2+ + H2O

To balance this equation, you need to add coefficients to each molecule or ion so that the number of atoms on both sides of the equation is equal:

2H2O2 + 5MnO4- + 6Fe2+ → 5O2 + 5Mn2+ + 6H2O

Now the equation is balanced.

6. Chlorine gas, water, and sodium chloride are produced when hydrochloric acid is added to sodium hypochlorite, NaOCl:
2HCl + NaOCl → Cl2 + H2O + NaCl

This equation is correctly balanced.

7. Sodium hydroxide reacts with ammonium chloride to produce ammonia gas, water, and sodium chloride:
NaOH + NH4Cl → NH3 + H2O + NaCl

This equation is correctly balanced.

I hope this helps! Let me know if you have any further questions.
