7. A balloon at 0.98 atm contains 0.16 mol of CH4, 0.23 mol of N2, 0.012 mol of He and 0.018 mol of H2. What are the partial pressure of each gas? 8. A gas in a 2.00 L of ballon weigh 7.14 g at 2.00 atm and 27.0°C. What is the molar mass of the gas? 9. Sulfuric acid (H2SO.), the industrial chemical produced in greatest quantity (almost 45 million tons per year in the United States alone), is...

Chapter 5 and Chapter 10 Problem solving (please practice the following questions and make sure that you understand the principles behind: you can find Ar from textbook or website I. A 145 g sample of copper metal at 100.0°C is placed into 250.0 g of water at 25.0°C in a calorimeter. When the system reaches thermal equilibrium, the temperature of the water in the calorimeter is 28.8°C. Assume the calorimeter is perfectly insulated. What is the specific heat capacity of...
