A65.0-gram sample of some unknown metal at 100.0° c is added to 100.8 grams of water at 22.0° c. the temperature of the water rises to 27.0° c. if the specific heat capacity of liquid water is 4.18 j/ (°c × g), what is the specific heat of the metal?

During chemistry class, carl performed several lab tests on two white solids. the results of three tests are seen in the data table. based on this data, carl has concluded that substance b must have bonds.
