# Thermodynamics and Specific Heat

You are given 10.0 grams of a mixture of NaNO3 and KF. You dissolve this

mixture in 100.0 grams of water, and the temperature rises by 1.02°C. Calculate the mass of each salt in the original mixture. Assume that the specific heat of the solution is 4.18 J/g°C.

Useful information: Enthalpy of solution of NaNO3: +20.5 kJ/mol

Enthalpy of solution of KF: -17.7 kJ/mol

#### Solution Summary

This solution provides step-by-step explanations in how to determine the mass of each salt in the original mixture using the specific of solution and enthalpy of the solution.

Thermo-chemistry

1.) If 596 J of heat are added to 29.6 g of water at 22.9 degrees Celsius in a coffee cup calorimeter, what will be the final temperature of the water?

2.) A 5.037 g piece of iron heated to 100. degrees Celsius is placed in a coffee cup calorimeter that initially contains 27.3 g of water at 21.2 degrees Celsius. If the final temperature is 22.7 degrees Celsius, what is the specific heat capacity of the iron (J/g, degrees Celsius)

3.) The specific heat of aluminum is 0.89 J/g, degrees Celsius. How much energy is required to raise the temperature of a 15.0 g aluminum can 18 degrees Celsius?

4.) One liter of an ideal gas at 0 degrees Celsius and 10 atm was allowed to expand to 1.89 L against a constant external pressure of 1 atm at a constant temperature. The enthalpy change (delta H) for this process is -901 J. Calculate q, w, and delta E.

5.) The heat capacity of a bomb calorimeter was determined by burning 6.79 g methane (heat of combustion= -802 kJ/mol) in the bomb. The temperature changed 10.8 degrees Celsius.

a. What is the heat capacity of the bomb?

b. A 12.6 g sample of acetylene, C2H2, produced a temperature increase of 16.9 degrees Celsius in the same calorimeter. What is the heat of combustion of acetylene (kJ/mol)?
