Alance the equations: H2 +Cl2 → HCI KNO3 → KNO2 + 02
Li + O2 → Lizo
Fe + O2 → Fe2O3
Fe2O3 + CO → Fe + CO2

H2 +Cl2 → 2HCI

2KNO3 → 2KNO2 + 02

4Li + O2 → 2Li2O

4Fe + 3O2 → 2Fe2O3

Fe2O3 + 3CO → 2Fe + 3CO2

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
