I drew 6 different graphs for this investigation. United Kingdom[ edit ] This section needs to be updated. I made sure that I had everything before I started. This shows that as you increase the independent variable the concentrationthe other variable the time taken for the experimentwent down.
There are 2 outliers Improvements and further investigations: Sodium thiosulphate is a colourless, crystal like compound and is used for dyes and is also a salt.
I could test this by asking one of my peers to follow the instructions and then asking for their feedback. I did, however find some outliers Igcse chemistry coursework my results.
Graphs All of the graphs that I drew for this investigation show a negative correlation. We prepare students to be world-ready and we discuss recent discoveries and career prospects in our chemistry programme. You should have the ability to follow a logical sequence of instructions and to be able to recall factual material.
It is often used as a chemical intermediate and in petroleum production, food processing, pickling, and metal cleaning. How is the course assessed? We also crafted lesson plans and materials that closely follow the college-based assessment. Wow thanks for that.
The results for 1, 2 and 4M keep showing outliers. I have used reliable resources to research this information and it all confirms my conclusion.
The points in the top right are quite far down so this shows a negative correlation. The star is one of many billions of stars in a galaxy which, in turn, is one of many billion galaxies in a constantly expanding Universe. I have highlighted the 2M results on my tables because it seems as though there is a problem with that set.
Volcanoes shot molten rock and gases from this surface and the first atmosphere mainly carbon dioxide and water vapour was formed. I wrote down my results and then moved on to the next concentration of sodium thiosulphate. These are areas such as: The size of the error bars is quite small so I think I can say that my data is quite accurate except for the 2M result which is quite a long error bar.If you wish to take Chemistry exams in (or later years), you will need to study our IGCSE Chemistry course which does not include coursework.
