(07.04 HC) A 76.0-gram piece of metal at 96.0 °C is placed in 120.0 g of water in a calorimeter at 24.5 °C. The final temperature in the calorimeter is 31.0 °C. Determine
the specific heat of the metal. Show your work by listing various steps, and explain how the law of conservation of energy applies to this situation. (8 points)

Maybe you should get some from your teacher and learn more so you can get your grades up and maybe study a bit more

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).
