#3.1
know that chemical reactions in which heat energy is given out are described as exothermic, and those in which heat energy is taken in are described as endothermic
#3.2
describe simple calorimetry experiments for reactions such as combustion, displacement, dissolving and neutralisation
#3.3
calculate the heat energy change from a measured temperature change using the expression \(Q = mcΔT\)
#3.4
calculate the molar enthalpy change (ΔH) from the heat energy change, Q
#3.5C
draw and explain energy level diagrams to represent exothermic and endothermic reactions
#3.6C
know that bond-breaking is an endothermic process and that bond-making i s an exothermic process
#3.7C
use bond energies to calculate the enthalpy change during a chemical reaction
#3.8
practical: investigate temperature changes accompanying some of the following types of change:
- salts dissolving in water
- neutralisation reactions
- displacement reactions
- combustion reactions.
