Chemistry · Secondary 4 · Medium · Exothermic and endothermic reactions
A student reacts 40.0 cm³ of 1.00 mol/dm³ copper(II) sulfate solution with excess magnesium powder in a polystyrene cup.
The temperature rises by 9.0 °C.
Assume the mass of the solution is 40 g and its specific heat capacity is 4.18 J g⁻¹ °C⁻¹.
Calculate the heat energy released in this reaction.
