2090 J of heat energy are removed from 40 g of a silvery metal at 81.7°C. The temperature falls to 30°C. According to the chart below which metal would it most likely be? (Show work!) METAL SPECIFIC HEAT (J/goC)
-aluminum. 0.90
-magnesium. 1.01
-silver 0.234
-tin. 0.220
-zinc. 0.386

i think that the answer is c

there are two significant figures.

the population of unionid mussels in the hudson river decreased after zebra mussels were introduced. zebra mussels, a nonnative species, competed with the unionid mussels for food. the zebra mussels were able to outcompete the unionid mussels, allowing the zebra mussel population to increase dramatically over six years. the unionid mussel population decreased due to a lack of food.

hope this :
