Using your lesson notes and research into enthalpy and entropy
complete the following assessment activities:
1) Enthalpy investigations
Carry out the following investigations to demonstrate accurate
measurements of enthalpy changes. You will determine by calculation
Task 1 different enthalpy changes in kJ per mole from the temperature
changes measured for:
The dissolving of anhydrous sodium carbonate in water
The dissolving of ammonium chloride in water
The neutralisation of hydrochloric acid with sodium hydroxide
Reaction of sulfuric acid and magnesium
The combustion of an alcohol
You will need to research suitable methods to safely measure the
