Answer:
For pure substances, the mass and volume will always be the same or will always change the same way because all substance are the same throughout.
While for mixtures, you can have varying amount of each component therefore mass and volume will not change the same way for substances
It is nonpolar because neither side is more electronegative/greedy than the other, and the electrons are shared equally, therefore forming no positive/negative charge on opposite ends.
