The freezing point of a 1.00 molal aqueous solution of calcium chloride (cacl2) is lower than the freezing point of a 1.00 molal aqueous solution of ethylene glycol (c2h6o2). why are the freezing points of the two solutions different?
oxidation or combustion
5o₂ + c₃h₈ ⟶ 3co₂ + 4h₂o
you could call this an oxidation reaction, because the propane is reacting with oxygen.
you could also call this a combustion, because the reaction is so fast that the propane burns with a flame.
