Apart from boiling point and flammability, what other quality does the size of the molecules in hydrocarbons affect?

Explanation:

apart from boiling point and flammability viscosity density and solubility are those qualities of hydrocarbon which are effected by their size

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
