I think i can help you with this question, but i think the 22 you meant to put in the initial temperature.

Because we have less hcl, 15 milliliters at one molar, than the 35 milliliters sodium hydroxide, this is our limiting reactant.
00:20
We can calculate the moles of hcl reacting by taking the volume, 15 milliliters is 0 .015 liters, and multiplying it by the concentration, 1 mole per liter.
00:35
This gives us 0 .0150 moles of the limiting reactant hcl.

This will be important when we calculate delta h.

To determine the heat evolved, the heat for the reaction is going to be equal to negative heat of the solution, because if the reaction releases heat, the solution absorbs it, and the signs need to be different.

Q represents heat.

Heat of the solution will be the specific heat of the solution.

I assume they want you to use 4 .184 joules per gram degree celsius...
