7) A 100.0 mL sample of 0.300 M NAOH is mixed with a 100.0 ml sample of 0.300M HNO, 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 NaNO) for the neutralization reaction between aqueous NaOH and HNO2. 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.
