Atmospheric concentrations of methane and ozone can vary depending on the location and altitude. Calculate the rate of the reaction at 288 K for a methane concentration of 1.7 ppm (by volume) and an ozone concentration of 5.2 ppm (by volume). Note that 1 ppm of CH4 by volume means 1 L CH4/106 L air. Assume standard temperature and pressure (STP) so that 1 mol of gas occupies 22.4 L.

If you burn 10 kilograms of wood in a fire (combustion) what is the weight of the products after the fire has finished burning the wood?

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
