    On the question how else can u dispose polymers i put burn them. would I get a mark?
    and for test between alkanes and alkenes did you have to say that you condense the gases first?
    and finally for the protection question for chlorine gas, I wrote wear a gas mask?

    You can't burn them as they cause pollutants - you have to put them with starch molecules.
    Alkenes are already hydrocarbons and the test for them is bromine water decolourises.
    Chlorine gas is fine

    gas mask may be acceptable it depends how lenient they are being, they were more looking for a 'ventilated room' and yeah you would have to inject with starch granules, recycle or allow them to degrade in light

    1. Not my spec
    2. Bromine water turns alkenes colourless whereas alkanes remain orange (the colour of bromine water) due to an addition reaction.
    3. Yes, a gas mask would be sufficient.
