Review Problem 6.057 Incorrect. Did you use the correct temperatures for Initial and final states? Check the signs of your answers. A 6.57 g mass of a metal was heated to 105.70°C and then plunged into 100.0 g of water at 21.36°C. The temperature of the resulting mixture became 24.91 a) How many joules did the water absorb? joules b) How many Joules did the metal lose? joules c) What is the heat capacity of the metal sample? d) What...

4. Heat transfer: q = mass x Cs x ΔT and –qreaction = +qsolution a. A piece of metal with a mass of 8.6 g was heated to 100.0°C and dropped into a coffee cup calorimeter containing 402.4 g of water at 25.0°C. If the temperature of the water and the metal at thermal equilibrium is 26.4°C, what is the specific heat of this metal in J/g°C? b. How much heat energy must be added in order to boil a...
