When 50mL of .100M AgNo3 and 50mL of .100M HCl are mixed in a constant pressure calorimeter, the temperature of the mixture increases from 22.20 degrees to 23.11 degrees celsius. The temperature increase is caused by the foloowing reaction:AgNO3(aq)+HCl(aq)--> AgCl(s)+ HNO3(aq)
Calculate the delta H for the reaction in KJ/mol AgNO3, assuming that the combined solution has a mass of 100.00g and a specific heat of 4.18J/gc
