In the beaker, add a 25.0-g sample of aluminum at 180°c, and in the calorimeter, add 110-g of water at 20.0°c. select “show graph view” and “show microscopic view,” and then click “start” to run the reaction. (use the simulation to obtain the final temperature of the solution.) calculate the change in heat of the aluminum; show all calculations. calculate the change in heat of the water; show all calculations. are the two values the same? why or why not?
