Calculate the enthalpy change, ΔH, for each reaction in kJ mol–1.
reaction 1: K2CO3(s) + 2HCl(aq) → 2KCl(aq) + CO2(g) + H2O(l)
Mass of test tube with potassium carbonate/g 25.12
Mass of test tube after emptying out potassium carbonate/g 23.04
Mass of potassium carbonate used/g - 2.08
Start temperature/°C 23.2
Highest temperature/°C 28.4
Temperature change/°C 5.2
