DW, a lot of people have difficulties at A-Level. The first paragragh states that a. GCSEs leave you totally unprepared for real study and the teaching in this area is terrible! Re: Molecular formula calculations help (AS Chemistry). Also bear in mind that this is a non-standard question. In The Anabolic Gameplan e-book, stacking test testosterone cypionate section, the paragraph above diagram 17. AQA A Level Chemistry Exam revision notes” discussion on The Student Room's Chemistry forum. Hello, I am a mature student currently studying AQA A level chemistry as a private candidate and its going well so far. Calculate the enthalpy change for the reaction CaF2 + H2SO4 → 2HF + CaSO4, given that the enthalpies change of formation of CaF2, H2SO4, HF and CaSO4 are -1220, -814, -271 and -1434 kJmol-1 respectively. I wonder why biology, chemistry, and even physics students aren't typically required to take stats in college. Based on my experience in bio and chem courses, many of our labs and experiments typically require some level of statistical analysis. There was a calculation in one of the questions which could only be worked out using quadratic equations, which are not part of the syllabus for Chemistry A Level. I struggled too, until I took things into my own hands and went through the Calculations for A-level Chemistry and Calculations for A-level physics books. You'll use this calculation throughout science. One of the most useful calculations to be able to perform is determining the mean or average of a set of numbers. Just like a pocket calculator or a symbolic math program (such as Mathematica or MAPLE), MolCalc allows one to assign “higher level” chemical problems that are not practically possible to solve otherwise.
