1. Ammonia reacts with oxygen according to the following equation: 4NH3(g) + 5O2(g) 4NO(g) + 6H2O(g) How many grams of NO are created by the reaction if 1.50 g of NH3 react with 2.75 g of O2?2. If 55.8 mL of BaCl2 solution is needed to precipitate all the sulfate ions in a 752-mg sample of Na2SO4 (forming BaSO4), what is the molarity of the BaCl2 solution?3. Suppose that the volume of a particular sample of Cl2 gas is 8.70 L at 895 torr and 24⁰C. At what pressure will the volume equal 6.00 L if the temperature is 58⁰C?4. A mixture containing 2.50 g each of CH4(g), C2H4(g), and C4H10(g) is contained in a 2.00 L flask at 15⁰C. Calculate the partial pressures of each gas and the total pressure in the flask.5. What is the correct order in the electromagnetic spectrum, in order of increasing wavelength? a) microwave, visible light, xrays b) IR, UV, radio waves c) UV, visible light, radio waves d) radio waves, xrays, IR6. What is the energy (in Joules) of a wave with a wavelength of 955 μm?7. For what situation would more corrections to the ideal gas law be needed? a) 45.3 mol in 6 mL b) 4.53 mol in 6 mL c) 45.3 mol in 6 L d) 4.53 mol in 6 L8. Write the electron configuration for P and circle those that are valence
