A

Explanation:

i dont explain wat can you do

Explanation:

Look here,

3CuCl2 + 2Al --> 2AlCl3 + 3Cu

On

LHS = 3Cu , 3 × Cl2 = 6Cl and 2Al

RHS = 2Al , 2 × Cl3 = 6Cl and 3Cu

Hence,

LHS = RHS and the above equation is balanced

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.

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
