Page 50 Course Reader Explanation

Page 50 of the course reader asks us to determine if Gold can dissolve in 1M nitric acid to for 1M Au3+ solution. We are given the E standard for the reduction of nitric acid (0.96 V) and the oxidization of gold (-1.50 V). Why then does he add the two values instead of subtracting to get E standard ...

The specific heat capacity of copper is 0.38 Joules per degree celsius grams and of water is 4.18 Joules per degree celsius grams. So you plug in these va...
