Rates of Reaction Coursework Aim: To find out how different concentrations of sodium thiosulphate (Na S2 O3) affects the speed of its reaction with Hydrochloric acid (HCL). Introduction When Sodium Thiosulphate and Hydrochloric acid react they produce a cloudy precipitate. Both of the chemicals are clear solutions and they react together to form a yellow precipitate of sulphur‚ the equation for this reaction is: Na2 S2 O3 + HCL‚ H2 O + NaCL + SO2 + S Sodium Thiosulphate + Hydrochloric

I opened up my speech by saying how I didn’t have anything nearly as interesting to say about myself compared to the girl that had gone before me; I guess that was a nervous mechanism‚ since I already started doubting myself from the beginng.

The movie took off with Steve Jobs talking in a melodramatic way to the audience‚ it seems but as the angle of the scene shifts‚ it was shown that he was actually talking to a director and that they were currently in the middle of shooting a commercial which is for the Apple Computer. The scene then changes showing
