Ocr Chemistry Biochem And Trends Patterns AnswersWatch
Good luck everyone.
p.s. Are the 2 chemistry exams most people's last exams? For those who still have more exams, sorry, and hope they go well.
And just to give you an idea of how bad I am at Biology - I did seperate science GCSE's, got A* Chemistry, A Physics and a C in Biology. Thats why biochem is so bad for me.
The big will be on construction of redox reactions, with some synopic element to it. like potassium dichromate. uses of etc, equations, formulae. and also working out titration calculations.
there will be something on lattice energy, maybe a construction but will not be that straightforward. Nb 2:1 ratio of moles.
the idea of polarised anion is common so to is exothermic extent of lattice energy.
There will be reactions of period 3, might combine aluminium with something. learn all reaction condidtions and effects for period 3.
Maybe a grid, fill in structure etc.
I also do methods of anaysis and detection. not to bad.
i dont get all that h+ + - ---? M+ + 5H+
