The heat of neutralization of HCl (aq) by NaOH is -55.9Kj/mol H2) produced. If 50ml of 1.6M NaOH at 25.15 celsius is added to 25ml of 1.79M HCl at 26.34 celsius in a plastic foam cup calorimeter, what will be solution temperature be immediately after the neutralization reaction has occured?

Answer 1

I'm confused by the term "immediately after the neutralization reaction has occured?" Does that mean we aren't giving the solution time to reach equilibrium temperature wise. The second thing that bothers me about this problem is that you do NOT have any H2 gas released.
NaOH + HCl ==> NaCl + H2O
