Study help enthalpy change

1. A student added 100 cm3 of a 2.0 mol dm-3 of hydrochloric acid to 100 cm3 of 2.0 mol dm-3 sodium
hydroxide solution. The student recorded the temperature rise as 11.5 °C.

(a)
Write the equation for the reaction.
(b)
Calculate the heat given out in the reaction. (Assume the specific heat capacity of the reaction mixture to be 4.2 J K-1 g-1)
(c)
Work out how many moles there are in 100 cm3 of the 2.0 mol dm-3 solutions of acid and alkali.
(d)
From the answers above, what is the molar enthalpy of neutralization for the reaction between HCl and NaOH solutions?
(e)
Draw the apparatus the student could have used to perform the experiment.
(f)
Consider the sources of experimental error and the effect they would have on the student’s value for the enthalpy of neutralization.
