Transcribed Image Text:A 100.0 mL sample of 0.300 M NaOH is mixed with a 100.0 mL sample of 0.300 M HNO 3 in a coffee cup calorimeter. If both solutions
were initially at 35.00°C and the temperature of the resulting solution was recorded as 37.00°C, determine the AH° rxn (in units of kJ/mol
NaOH) for the neutralization reaction between aqueous NaOH and HCI.
The specific heat capacity of water = 4.18 J/°C.
Assume
1.) that no heat is lost to the calorimeter or the surroundings
2.) that the density and the heat capacity of the resulting solution are the same as water.
