Suppose that the calorimeter shown here was used to determinethe energy change for an acid-base reaction.
An acid/base reaction solution was made by combining 150 mL of 0.5 M HCl of 50 mL of 1.00 M NaOH, to make 200.0g of solution
Other data for the system include:
Initial temperature of solution36.3C
Specific heat capacity of solution4.184 J/gC
Enthalpy change for neutralization-56 kJ/molAssume the volumes of acid and base are additive.
Calculate the final temperature of the reaction mixture (assumingno heat loss to the surroundings).
