6.5—Experimental data to calculate: i energy transferred in a reaction recalling and using the expression: energy transferred

Be able to use experimental data to calculate: i energy transferred in a reaction recalling and using the expression: energy transferred (J) = mass (g) × specific heat capacity (J g-1 °C-1) × temperature change (°C) ii enthalpy change of the reaction in kJ mol⁻¹ This will be limited to experiments where substances are mixed in an insulated container and combustion experiments using a suitable calorimeter.

Use —experimental data to calculate: i energy transferred in a reaction recalling and using the expression: energy transferred to connect the rule to the data and decision in the question.

This matters because —experimental data to calculate: i energy transferred in a reaction recalling and using the expression: energy transferred determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —experimental data to calculate: i energy transferred in a reaction recalling and using the expression: energy transferred to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Experimental data to calculate: i energy transferred in a reaction recalling and using the expression: energy transferred is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
