A metal with a mass of 180 g and an initial temp. of 150°C is lowered into a calorimeter that contains 76.5 g of water at a temp. of 26.4°C. The calorimeter rises to a final temp. of 34.8°C. Calculate the specific heat capacity of the metal.

Ibelieve the answer is d

The population of unionid mussels decreased after zebra mussels were introduced. zebra mussels competed with the unionid mussels for food. the zebra mussels were able to displace the unionid mussels, allowing the zebra mussel population to increase  over the years. the unionid mussel population decreased because  of lack of food.

D=m/v =57.9/3 = 19.3 g/cm^3
