Ex-MOE Teacher A Levels H2 Chemistry @ BedokFunland JC. Jim -- snap -- approaching my 50th year, I still calculate dilutions/amounts/volumes exactly the way I was taught to do it in O-level chemistry classes. It will make life in Chemistry A level loads easier. Candidates are required to bring their lab coat, goggle, exam registration slip, identity card and calculator to the exam. Also, candidates Remember, practical paper takes up 23% of the AS Chemistry paper. 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. Calculate the % by volume of dinitrogen monoxide in the gas mixture. Stephen says: April 14, 2011 at 9:33 pm. Edited by UltimaOnline 22 Jul `09, 3:26PM. When you start having to calculate moles of liquids and gases, I can show you 2 other formula triangles that will help you as well with the equations.
