Where do you find the values needed to find the standard heat of reaction in this problem? How do you calculate it as well?

Thanks!

You can find these values in appendix 2 in the beginning of the book. Find the energy released by the oxidation of zinc. Then use the heat capacity of HCl (same as water) and mass q=mcdetaT to solve for final temp.
