If I was using solids, I could investigate surface area and for gases I could investigate pressure In concentration I looked at five different concentration of HCl The volume of HCl stayed the same; also the volume of sodium thiosulphate stayed the same, the concentration of sodium thiosulphate stayed the same.
The alkali metals caesium cesium and rubidium were discovered by Aqa a level chemistry coursework of their line spectrum and helium identified from spectral observation of our Sun.
Hydrochloric acid is colourless, poisonous and highly acidic. The rate of reaction is the speed of a reaction. Conclusion In my investigation, my data and my graphs proved that my hypothesis was correct.
The methods described give no recipe details or risk assessment, just basically what is needed, what you see and what you can or cannot deduce.
This shows that my data is quite accurate. 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.
Most acidic and alkaline solutions unless very dilute, VERY small quantities of acidic gases like chlorine, sulfur dioxide, nitrogen dioxide, very dilute bleaches. In my investigation, there was the limitation of room temperature. The room temperature could have affected my reaction and this could be the reason that I have some outliers.
Other removed qualifications include a variety of design technology subjects, which are reformed into a single "design and technology" subject with multiple options, and various catering and nutrition qualifications, which are folded into "food technology".
It is permissible to take A Levels in languages one already speaks fluently, or courses with overlapping content, even if not always fully recognized by universities.
Questions on practical techniques and data analysis 40 marksquestions testing the specification 20 marks multiple choice questions 30 marks Practical Assessment: I drew 6 different graphs for this investigation.
Use of rate of reaction in industry The chemical industry makes medicine and many other substances such as; Limestone - this is used for building Sulphuric acid — used to make other substances Ammonia - used to make fertilisers.
The independent variables in our experiment are the concentration of hydrochloric acid. The high temperature promotes electrons to higher energy levels and the electrons re-emit the energy as photons of light as they go back to their normal stable level.
This shows that there is a difference in the data which proves accuracy. Conclusion In my investigation, my data and my graphs proved that my hypothesis was correct. Your course materials will be sent by post or via email, you choose!
I will discuss these further in my evaluation.
I decided that it would be best for me to use a bold marker pen to make the mark more visible under the conical flask. Reactions that happen quickly have a high rate of reaction.
United States[ edit ] In the United States of America USA the high school diploma is the qualification generally required for entry into colleges and universities.
Students who wish to study in the United Kingdom may additionally participate in the Advanced Placement AP or International Baccalaureate IB programs, which are considered to be at the level of the A Level qualifications and earn points on the UCAS Tariff  or may opt to take A Level examinations in British international schools or as private candidates.
This can help me identify any faults.This site contains notes, exercises, exam questions and tests to cover the new AQA A-level Chemistry course. Sections also exist to cover the legacy AQA and OCR A Chemistry Specifications.
Jun 19, · New AQA Level 3 Applied General Science. Discussion in 'Science' started by dominicgaudious.net, Nov 25, We have spent the time since the exam completing the unit 2 coursework, we have the biology almost completed, but I think the chem and the physics will be quicker to complete.
and especially finding marking the chemistry. There is a full interactive specification for quick consultation. Students of AS and A2 level chemistry (AQA specification) will probably find the chemistry notes sections the most useful. For general queries regarding the AQA qualifications you can visit the official AQA website.
welcome to the new aqa a-level chemistry course - 1st year and as-level. FINAL MARKING GUIDELINES – A-LEVEL CHEMISTRY – CHM6T/Q14 – JUNE 3 of 10 Guidance for teachers marking Chemistry ISAs General principles In general, you are looking for evidence that the student knows and understands the key idea required by the Marking Guidelines.
