While trying to make ice cream, a well meaning student discovers that he is out of nacl to use in the ice cream maker. he remembers that his roommate has some "salt" (cacl2) that they used on the sidewalk last winter. unfortunately, he puts this in instead. he adds 111 g cacl2 (formula weight = 111 g/mol) to 4.00 l (4000 g) of water. the salt and water are initially at 0.00°c. cacl2 (s) ca2+ (aq) + 2 cl- (aq) ah = - 84.0 kj/mol a. what is the heat flow (9) under these experimental conditions? q (kj) = submit answer tries 0/2 b. assuming that the specific heat of the solution is 4.184 j/g°c, what is the final temperature of the solution? tinal (°c) =
