To do this I would make sure that: Once sufficient oxygen was present, animal life began to evolve. These are circled on my graphs.
You will benefit from our personal tutor support for a period of up to 18 months from the date of enrolment. IGCSE Chemistry The course Chemistry supplies you with the knowledge and understanding so that you can engage with science- based issues in an informed way.
You should have the ability to follow a logical sequence of instructions and to be able to recall factual material.
You will look at the two different types of organic compounds: I have calculated the gradient of my line to support my hypothesis and found that: However, its scope reaches out beyond the laboratory into every aspect of our lives — to our understanding of the nature of our planet, the environment we live in, the resources available to us and the factors that affect our health.
For every one M increase, the rate for reaction increases by 2.
Conclusion In my investigation, my data and my graphs proved that my hypothesis was correct. Sodium thiosulphate is a colourless, crystal like compound and is used for dyes and is also a salt.
I will be timing and watching: In my scatter graph with line of best fit, most of the points are close to the line. Nitrogen entered the atmosphere from bacteria. Section 4 Physical chemistry looks at acids, alkalis and salts and chemical reactions: While there are no strict entry requirements for this course, it is strongly recommended that you have the ability to read and write English effectively.
Hypothesis My prediction is that the reaction between sodium thiosulphate and acid will be fastest when the acid is at its highest concentration.
My conclusion is justifiable because I have backed it up with points from my data and I have proved all the points that I made.
This book thoroughly covers the Cambridge International Examinations CIE Chemistry syllabus and includes features which are aimed at helping you grasp the concepts and detail involved.
Full feedback to the student on their work by email until they attain the examination grade they are happy with. In my investigation, there was the limitation of room temperature.
Keep the size of my measuring flask is the same size; this should hopefully make my experiment much fairer and accurate. The introduction to each chapter aims to highlight some of the more novel aspects of chemistry — from unusual alloys and the visualisation of the bonding in molecules to the analytical laboratory on the surface of Mars.
I will discuss these further in my evaluation. Volcanoes shot molten rock and gases from this surface and the first atmosphere mainly carbon dioxide and water vapour was formed. Yes, but this course is self-contained so no additional textbooks are required, all texts are included within the course.
The conical flask and all other equipment must be clean as any impurities may contaminate my experiment. Nitrogen entered the atmosphere from bacteria.
Aim My aim is to investigate how changing the concentration of reactants can change the rate of reaction between hydrochloric acid and sodium thiosulphate. Section 3 Organic chemistry looks at the chemistry of carbon. Details of our guaranteed test centres are included with your course materials.
