A neutralization reaction occurs when 100.0 mL of 0.500 mol/L lithium hydroxide and 100.0 mL of 0.500 mol/L of nitric acid are mixed in an insulated cup. Initially, the solutions are at the same temperature. If the highest temperature reached during mixing was 24.5 oC, what was the initial temperature of the solutions? Include a balanced equation and show all your work. (5 marks)
