Balancing Chemical Equations:

To balance chemical equations, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's go through each equation and balance them one by one.

1. Ba + HCI → BaCl2 + H2 - To balance the equation, we need to have the same number of atoms on both sides. - The equation is already balanced.

2. Li + H2O → LiOH + H2 - To balance the equation, we need to have the same number of atoms on both sides. - The equation is already balanced.

3. CaCO3 + HCI → CaCl2 + CO2 + H2O - To balance the equation, we need to have the same number of atoms on both sides. - The balanced equation is: CaCO3 + 2HCI → CaCl2 + CO2 + H2O.

4. Al + WO3 → W + Al2O3 - To balance the equation, we need to have the same number of atoms on both sides. - The balanced equation is: 2Al + 3WO3 → 3W + Al2O3.

6. NH3 + O2 → N2 + H2O - To balance the equation, we need to have the same number of atoms on both sides. - The balanced equation is: 4NH3 + 5O2 → 4N2 + 6H2O.

7. Ca + HCI → CaCl2 + H2 - To balance the equation, we need to have the same number of atoms on both sides. - The balanced equation is: Ca + 2HCI → CaCl2 + H2.

8. Al + Cr2O3 → Al2O3 + Cr - To balance the equation, we need to have the same number of atoms on both sides. - The balanced equation is: 2Al + 3Cr2O3 → Al2O3 + 6Cr.

9. KNO3 → KNO2 + O2 - To balance the equation, we need to have the same number of atoms on both sides. - The balanced equation is: 2KNO3 → 2KNO2 + O2.

10. C2H6 + O2 → CO2 + H2O - To balance the equation, we need to have the same number of atoms on both sides. - The balanced equation is: 2C2H6 + 7O2 → 4CO2 + 6H2O.

11. C2H4 + O2 → CO2 + H2O - To balance the equation, we need to have the same number of atoms on both sides. - The balanced equation is: C2H4 + 3O2 → 2CO2 + 2H2O.

12. CO + O2 → CO2 - To balance the equation, we need to have the same number of atoms on both sides. - The balanced equation is: 2CO + O2 → 2CO2.

13. NaNO3 → NaNO2 + O2 - To balance the equation, we need to have the same number of atoms on both sides. - The balanced equation is: 2NaNO3 → 2NaNO2 + O2.

14. AgNO3 → Ag + NO2 + O2 - To balance the equation, we need to have the same number of atoms on both sides. - The balanced equation is: 2AgNO3 → 2Ag + 2NO2 + O2.

15. Al + HCI → AlCl3 + H2 - To balance the equation, we need to have the same number of atoms on both sides. - The balanced equation is: 2Al + 6HCI → 2AlCl3 + 3H2.

16. SiO2 + HF → SiF4 + H2O - To balance the equation, we need to have the same number of atoms on both sides. - The balanced equation is: SiO2 + 4HF → SiF4 + 2H2O.
