Essentially the stronger the forces the higher the melting point... Here is a list of interemolecular forces (the first will be the weakest).
1) Dispersion forces (Exhibited by evrey molecule) (Weakest)
2) Dipole-Dipole
3) Hydrogen bonding
4) Ionic bonds (Strongest)
The stronger the forces it has then the higher the melting point. Also aromatic structures have a higher melting point as well. A general rule of thumb is, the larger the structure is then the higher thee melting point it.
That would be helium, with a melting point of 0.95 K (-272.20 °C)—although this happens only under considerable pressure (~25 atmospheres). At ordinary pressure, helium would remain liquid even if it could be chilled to absolute zero.
In balancing reactions, the number of atoms on each side should be of equal number. It is the most important rule in reactions. Also, we should know the correct substances involved in the reaction. We do as follows:
