Ammonla has been studied as an alternative "clean" fuel for Internal combustion engines, since Its reaction with oxygen produces only nitrogen and water vapor, and In the liquid form it is easily transported. An Industrial chemist studying this reaction fills a 2.0 L flask with 1.2 atm of ammonia gas and 1.4 atm of oxygen gas, and when the mixture has come to equilibrium measures the partlal pressure of nitrogen gas to be 0.36 atm. Calculate the pressure equilibrlum constant for the combustion of ammonia at the final temperature of the mixture. Round your answer to 2 significant digits.

Gypsum is a relatively soft rock made of CaSO4. Rainwater percolates through gypsum, dissolves some of the rock, and eventually becomes saturated with Ca2+ ions and SO²- ions. A geochemist takes a sample of groundwater from a cave and finds that it contains 8.4 x 10-3 M SO42- and 5.8 x 10-3 M Ca²+. (The ratio is not 1:1 because other sulfate rock contributes some of the SO42- ions to the solution.) Use these data to determine the solubility product of CaSO4.
