Calculate the approximate volume of water that must be added to 250mL of 1.25N solution to make it 0.500 N

i think it's c. i'm not sure but i think so.

if you're asking what comes out, it's steam.

the correct answer would be b) volume versus temperature, because they are also directly proportional.

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.
