Banned Chemicals in Chemistry

    Anybody here doing Chemistry going to learn the experiments we can no longer do? I've covered the Organic because there's only a limited amount they can ask but we didn't even study the Experiment on Le Chatelier's Principle

    learn off the definition.

    it could come up in section B.

    our chemistry teacher asked us out of the blue on Monday to write the 3 equations associated with the experiment. By coincidence i studied it on Saturday :D and got all 3!

    The experiments can still be asked even though we aren't able to do them. The Le Chatelier ones are grand enough from what I remember (haven't looked at equilibrium in a while!) so there's no point not learning them really!

    Worth noting that Le Chatelier's principle is the #1 most common definition in LC chemistry!

    Do the equilibrium chapter, its so easy and comes up all the time.

    Also, you still have to learn all the banned chemical experiments even though we didn't do them

    i bet ya t. lyons told ya that :D

    Oh don't worry I know all the definitions its just that particular experiment. Came up last year but I'll give it a look over. Sound!

    Don't count out ethanal or ethanoic acid. they're due up, especially the first. even though they are banned, they can still be asked in theory. Phenolphthalein is also banned but the experiment (vinegar) can also be asked.

    Of course =) decent chance of them popping up this year
