how would the calculations be different if a small mass of ice were added to the calorimeter along with the metal sample? Assume you know the mass of the ice. Explain your answer
Homework Answers
On adding ice to calorimeter there will a extra term coming related to energy which is basically latent heat of fusion of ice which is required to melt the ice.

A 25 g cube of metal was heated in a hot temperature bath to 80oC and then added to 50 mL of deionized water. Using the following graph, explain how you would determine the temperature change that has occurred in the system. The metal was added to the calorimeter (Styrofoam cup with water) at 180 seconds. What is the initial temperature of the water and the metal? What is the final temperature of the metal and the water? What occurred...

An ice cube of mass 9.0g is added to a cup of coffee, whose temperature is 90.0 °C and which contains 120.0 g of liquid. Assume the specific heat capacity of the coffee is the same as that of water. The heat of fusion of ice (the heat associated with ice melting) is 6.0kJ/mol. Find the temperature of the coffee after the ice melts. Use the equation given in the lab manual on page 86. Ignore the + (CC) (AT)...

If 15.0g of AlClsubscript(3) were added to the ice-water mixture, what would be the freezing point of the solution? Assume the experimental volume of solution was 65.3 mL, the experimental freeing point of solvent water was 0.5 degrees C, and Ksubscript(f) was 1.86 degreesC/M. Please show all work and math, this is for a lab report. Thank you!!

A 200 g aluminum calorimeter can contain 500 g of water at 20 C. A 100 g piece of ice cooled to -20 C is placed in the calorimeter. Find the final temperature of the system, assuming no heat losses. (Assume that the specific heat of ice is 2.0 kJ/kg K) A second 200 g piece of ice at -20 C is added. How much ice remains in the system after it reaches equilibrium? Would your answer to part b...
