When 50.0 mL оf 1.00 M hydrоchlоric аcid аnd 50.0 mL of 1.00 M sodium hydroxide аre mixed in a coffee-cup calorimeter, the temperature of the mixture increases from 21.00 ºC to 27.50 ºC. Determine if the reaction is exothermic or endothermic and calculate the absolute value of the total amount of heat released/consumed (in kJ) to 3 significant figures Assume that the mass of the combined solution is 100.0 g and the specific heat of the combined solution is 4.18 J/g-ºC.
