2. A gas canister containing 5.25 cubic meters of a mixture of gases at 8 deg C and 0.950 bar from an Arctic expedition was brough back by a team of specialists in atmospheric science to determine the amount of ozone remaining in the polar regions. One of their members, Engr. Arcilla was tasked with bubbling the mixture of gases through an excess amount an aqueous solution of potassium iodide to reduce the ozone to oxygen gas and oxidize the iodine ion to triiodide ion. (a.) Write the balanced redox reaction between ozone and potassium iodide. Exclude any spectator ion in the final balanced reaction (Assume Basic Medium) (b.) Upon reacting, the mixture is then titrated with 71.8 mL of 0.517 M of sodium thiosulfate, reducing all of the triiodide ion back to iodine ion and oxidizing the thiosulfate ion to tetrathionate (S40,²). What is the mole fraction of ozone in the gas canister sample?

The ideal gas law is a limiting law, in that it is expected to hold as pressure approaches zero. Suppose the following measured values have been obtained for oxygen gas at 273.15K. Based on the data, calculate R for each pressure value and create a table of pressure and R values (i.e. you are treating R as a variable rather than a constant at this point). Then create a plot R vs p and find the “best value” of R by determining the y-intercept of a straight line fit. (Be sure to label your axes including units).

Blue Water Gas is obtained by passing steam over red hot carbon enriched coal (coke). The gas is called "Blue" water gas because of its blue flame, a characteristic of the combustion of CO. A typical composition shows 4.7% CO2, 41% CO, 49% H2, 0.8% CH4 and 4.5%N2.

Trinitroglycerin, C3H5N3O9C3H5N3O9 (usually referred to simply as nitroglycerin), has been widely used as an explosive. Alfred Nobel used it to make dynamite in 1866. Rather surprisingly, it also is used as a medication, to relieve angina (chest pains resulting from partially blocked arteries to the heart) by dilating the blood vessels. At 1 atm pressure and 25°C, the enthalpy of decomposition of trinitroglycerin to form nitrogen gas, carbon dioxide gas, liquid water, and oxygen gas is -1541.4 kJ/mol. (a) Write a balanced chemical equation for the decomposition of trinitroglycerin. (b) Calculate the standard heat of formation of trinitroglycerin. (c) A standard dose of trinitroglycerin for relief of angina is 0.65 mg. If the sample is eventually oxidized in the body to nitrogen gas, carbon dioxide gas, and liquid water, how many joules of energy is released?
