The heat change, Δ H have to determine in kilo Joules per mole for the reaction calcium oxide (CaO) with water to produce Ca(OH) 2 . Concept introduction: The amount of heat required to change the temperature of a substance taking part in any reaction or phase transition is the fundamental theme of the calorimetric problems. Given: 1.045 g of CaO is added to 50.0 mL of water at 25.0 o C in a calorimeter, the temperature of the water increses to 32.3 o C. The specific heat of the solution is 4.18 J/(g. o C) and the calorimeter itself absorbs a negligible amount of heat. The reaction is C a O ( s ) + H 2 O ( l ) → C a ( O H ) 2 ( a q ) To determine: The amount of heat required to increase or decrease the temperature of the reaction.
