Combustion

IQ1: What energy changes occur in chemical reactions?

Students:

● conduct practical investigations to measure temperature changes in examples of endothermic and exothermic reactions, including:

– combustion

– dissociation of ionic substances in aqueous solution

● investigate enthalpy changes in reactions using calorimetry and 𝑞 = 𝑚𝑐𝛥𝑇 (heat capacity formula) to calculate, analyse and compare experimental results with reliable secondary-sourced data, and to explain any differences
