Question
A weather balloon contains 1.10 Times 10^5 moles of He, an ideal gas. At standard pressure, the volume of the balloon is 2.90 Times 10^6 L. What is the temperature of the He in the balloon in degree C? SCUBA divers breathe a mixture of helium and oxygen gasses for dives in excess of 150 feet. If 18.7 grams of oxygen gas and 10.2 grams of helium gas are both added to a 5.00 L SCUBA tank at room temperature, what will be the total pressure in the tank, assuming ideal behavior? 846.0 mg of a homoatomic diatomic ideal gas occupies a volume of 1.37 Times 10^3 cc at a temperature of 25 degree C and a pressure of 16.14 in. Hg. What is the identity of the gas? List the six possible changes of state as "pairs" of opposite processes (i.e., exothermic vs. endothermic) processes in the spaces below. IS THE OPPOSITE OF IS THE OPPOSITE OF IS THE OPPOSITE OF List the three endothermic changes of state. List the three exothermic changes of state. In degree F, degree C, and K, what is the normal boiling point of dihygrogen monoxide? What is the difference between sublimation and evaporation? Explain why increasing the surface area of a liquid also increases the rate of evaporation. Define the equilibrium state for dynamic equilibriums. Which of the three intermolecular forces can occur in the largest number of situations or scenarios?Explanation / Answer
