a student is asked to calculate the amount of heat involved in changing 10 grams of liquid bromine at room temperature (22.5 C) to vapor at 59 C. To do this, one must use tables 8.1 and 8.2 for information on the specific heat, boiling points, and heat of vaporization of bromine. in addition, the following step-wise process must be followed. A) calculate delta H for : Br2 (l, 22.5 C) --> Br2(l, 59.0 C) B)calculate delta H for : Br2(l, 59 C) --->Br2 (g, 59 C) C) Using Hess's law, calculate delta H for : Br2 (, 22.5 C)-->Br2 (g, 59 C)
