Explanation: because it is positively charged and protons are positive ions
Answer:
Salt
Explanation:
It is because it has a defined composition.
Compounds with different boiling points - b.
Only because<span> fractional distillationworks by having a temperature gradient in the column therefore different length hydrocarbons condence at different rays of different temperatures.This works because longer chain hydrocarbons have higher boiling points. </span>
