This explanation is for this equation
oxygen can be removed from metal oxides in chemical reactions. for example:

copper oxide + carbon → copper + carbon dioxide

2cuo(s) + c(s) → 2cu(l) + co2(g)

in this reaction, carbon is oxidised because it gains oxygen. at the same time, copper oxide is reduced because oxygen is removed from it.

so write the explanation for the displacement reaction for zinc+ iron sulphate= zinc sulphate+iron

it would be a gas formation

because it is

intermolecular forces are the forces between molecules or particles.

there are two kinds of van der waals forces: weak london dispersion forces and stronger dipole-dipole forces.

in molecule of water there are dipole-dipole forces between negatively charged oxygen from one molecule of water and positively charger hydrogen of another molecule of water.

hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (h), covalently bound to a highly electronegative atom such as flourine (f), oxygen (o) and nitrogen (n) atoms.
