zero particle volume
3
Q
ideal gas can be used to
A
relative molecular mas of simplemolecules
4
Q
low melting points of simple molec structures are due to
A
weak i.m forces between molecules
5
Q
High melting points of giant molec structures
A
due to large numbers of strongcovalent bonds in a regular repeating pattern

Q
ionic compounds form giant 3d lattice structure containing
A
ions in a regular repeating pattern.
7
Q
high m.p. of ionic substances due to
