Dinitrogen monoxide, N2O, reacts with propane, C3H8, to farm nitrogen, N2; carbon dioxide. CO2; and water, H2O. Write a balanced chemical equation for this reaction, treating all substances as gases. Include phases in your equation. Two reservoirs, separated by a closed valve (of negligible volume), are filled with the reactants (one on each side). The pressure of N2Ois measured to be 1.4atm. The pressure of C3H8is measured to be 1.2atm. Each reservoir has a capacity of 1.0L, and the temperature of the system is mg src=Images/HTML_99425-13-98QAP_image001.jpg alt="" align="top"/> e valve between the reservoirs is opened, and the chemical reaction proceeds. Assuming ideal gas behavior and constant temperature, what is the partial pressure of CO2after the reaction is complete? What is the partial pressure of N2Oafter the reaction is complete?

At 25.0C, helium molecules (He) have an average velocity of 1.26105cm/s, and methane molecules (CH4) have an average velocity of 6.30104cm/s. Calculate the kinetic energy of each type of molecule at 25.0C and determine which is greater. Express molecular masses in u for this calculation.
One method of analyzing amino acids is the van Slyke method. The characteristic amino groups (NH2) in protein material are allowed to react with nitrous acid. HNO2, to form N2 gas. From the volume of the gas, the amount of amino acid can be determined. A 0.0604-g sample of a biological sample containing glycine, CH2(NH2)COOH, was analyzed by the van Slyke method and yielded 3.70 mL of N2 collected over water at a pressure of 735 torr and 29 C. What was the percentage of glycine in the sample? CH2(NH2)CO2H+HNO2CH2(OH)CO2H+H2O+N2
