    Polymers (it's what the question asked) are unreactive/inert

    I'm not sure which question you are asking about but for the addition reaction I said that the molecule which is ethene goes to ethane.

    Well I wrote temperature and concentration first but then I crossed out temperature and wrote volume. That's because I read the question it specifically said what are two properties of the solution that should be kept the same to keep the amount of h202 the same. I didn't think temperature affects the amount of h202.. I don't know...

    Wait I think that question was saying which one of the following undergoes an addition reaction and I'm sure the one that is ethene becomes ethane as two hydrogen atoms are added on.
