A block of an alloy of mass 35.0 g and at a temperature of 19.54 °C is placed in a calorimeter containing 35.0 g of water at 84.57 °C. If the final temperature of the alloy and water is 61.03 °C, calculate the specific heat (in J/g/K) of the metal. The specific heat of water is 4.184 J/g/K. Express your answer to three significant figures in scientific notation

It takes 55.0 J to raise the temperature of an 11.0 g piece of unknown metal from 13.0°C to 24.8 °C. What is the specific heat for the metal? Express your answer with the appropriate units.

A chemical reaction takes place inside a flask submerged in a water bath. The water bath contains  8.80kg  of water at  20.5°C . During the reaction  66.3kJ  of heat flows out of the flask and into the bath. Calculate the new temperature of the water bath. You can assume the specific heat capacity of water under these conditions is  4.18·J·g−1K−1 . Be sure your answer has the correct number of significant digits.   °C

It takes 47.0 J to raise the temperature of an 9.90 g piece of unknown metal from 13.0°C to 24.6 °C. What is the specific heat for the metal? Express your answer with the appropriate units.

A 4.81 g sample of an unknown salt (MM = 116.82 g/mol) is dissolved in 150.00 g water in a coffee cup calorimeter. Before placing the sample in the water, the temperature of the salt and water is 23.72°C. After the salt has completely dissolved, the temperature of the solution is 28.54°C.   If 3.12 × 10³ J of heat was gained by the solution, what is the total heat for the dissolution reaction of the 4.81 g of salt?   How many moles of the unknown salt were used in the reaction ?     _______ J?

A chemical reaction takes place inside a flask submerged in a water bath. The water bath contains 3.40kg of water at 32.4°C. During the reaction 60.8kJ of heat flows out of the flask and into the bath. Calculate the new temperature of the water bath. You can assume the specific heat capacity of water under these conditions is 4.18·J·g−1K−1. Be sure your answer has the correct number of significant digits.
