    Circular motion

    Could someone please post some notes about circular motion, including electrons, satellites and planets. It doesn't seem to be in my book and the stuff I found online was way too complicated. Thanks.

    How was your Chemistry Atp

    I thought you had to write why it reacted. I explained how they ionised in water and everything. Lost three marks there.

    How was your Chemistry Atp

    I actually misunderstood one question. The question about barium sulfate. The part where you had to describe how to filter it and then wash with distiller water, I wrote something completely different.

    How was your Chemistry Atp

    Actually I meant the absolute last question. About the solubility in water. Something like 150g in 100cm^3 water.

    How was your Chem ATP paper ?

    Sorry but universal idicator is something different. I believe it is red in sulphuric acid and purple in ethanoic acid. The answer was a water bath. It is used to prevent the alcohol from igniting, since it is highly flammable.

    How was your Chemistry Atp

    Although an electric heater is safer than an open flame, a water bath is still always used. It makes the experiment much more safe and since the boiling point of ethanol never exceeds that of water there is no reason to not use it.

    How was your Chem ATP paper ?

    Actually I think barcodes are pretty specific when it comes to even single lines, but seeing as how every page had the barcode it might not be a problem.

    How was your Chemistry Atp

    Alcohol is highly flammable, and is never to be heated directly with a Bunsen burner. The answer was to use a water bath.
