Chemistry
A 100.0 mL sample of 0.76 M HCI at 23c was mixed with 100.0 mL of 0.76 NaOH at 23c in a coffee cup calorimeter and the following reaction occurred
The temperature of the solution increased and a maximum temperature of 28.2 degrees cleius was recorded. Assume that no heat was lost to the surroundings, the volumes were additive, the specific heat capacity of the solution was 4.184 j/go and the density of the solution was 1.00 g/mL
A) calculate the enathalpy change for the formation of 1.0 mol H2O in this reaction
B) is the reaction endothermic or exothermic
C) was the energy conserved in the process
