Please Clearly answer all 5 questions attached and all questions above the attachment. Please type answer or write clearly so that I am able to read it. 1. Give the molecular formula for: A gas consisting of single atoms A diatomic gas A gas consisting of molecules containing 3 atomsA gas consisting of molecules containing 4 or more atoms?2. What is the difference between a gas and a vapor?

3. Calculate the root-mean-square speed of O, gas molecules at 120 C. U(RMS) = [(3RT/MM)] ^1/2 R = 8.314 J/Kxmol 4. Consider the following reaction: 4NH,(9) + 50,(9) - 4NO(g) + 6H,O(g) If 25 L of O, are reacted with excess ammonia at a temperature of 22C and a pressure of 1.1 atm, calculate the volume in liters of the NO produced. 5. A mixture of gases contains 0.55 mol O,, 0.14 mol N,, and 0.10 mol Ar. The total pressure is 3.2 atm. Calculate the partial pressures of the gases
