Chemistry: thermochemistry: using q = mCΔT and Hess's law

There are 2 worksheets (and answers) as well as notes and worked examples (ws2). The resources would suit students aged about 14-17 years old depending on the course. WS2 is for more advanced students.

WS1 has 2 pages of questions where the student has to choose whether a reaction is either endothermic or exothermic, draw and label an energy profile. There are also some simple calculations to determine the amount of energy given off from a known mass of an organic compound.

WS2 contains notes, worked examples and 10 problems (and answers) focused on the equation Using q = mCΔT and Hess's law. The problems will be useful for students enrolled in Honors, AP or those who would like to sit the National Chemistry Olympiad competition. The problems are of straight forward to moderate difficulty.

With all the best intentions in the world, mistakes do get made. Please tell me if there is an error and I will correct it and organise to send you a corrected copy.

Key words: Hess's law, thermochemistry, enthalpy, heat, thermodynamics, calculations.
