Combustible vapor-air mixtures are flammable over a limitedrange of concentrations. The minimum volume % of vapor thatgives a combustible mixture is called the lower flammable limit(LFL). Generally, the LFL is about half the stoichiometric mix-ture, the concentration required for complete combustion of thevapor in air. (a) If oxygen is 20.9 vol % of air, estimate the LFL forn-hexane, C₆H₁₄. (b) What volume (in mL) of n-hexane (d=0.660 g/cm³) is required to produce a flammable mixture of hexane in 1.000 m³of air at STP?

Given: Temperature of H2O = 200C Pressure = 0.95 atm Initial Air Volume = 50mL Final Air Volume = 95mL Volume of O2 collected = 95mL - 50mL = 45mL Total Reaction time = 17mins Balanced equation for hydrogen peroxide decomposition: 2H2O2 ------ 2H2 + O2 Using the Ideal Gas Law (PV = nRT), calculate the grams of O2 produced in the reaction above(decomposition of hydrogen peroxide). (Hint: solve for n, and then convert moles of O2 to grams. Watch your units; you may need to convert some of your data into different units.)

What is the Molecular weight of a certain volatile liquid which is placed in 225 g flask which has total capacity volume of 252.17 mL. After the liquid was heated to 96.7 oC the gass volatilized and the weight of the flask measure 227.33g. What is the could be the MW of the volatile sample?
The oxidation of ethylene to produce ethylene oxide proceeds according to the equation2C 2H 4 +O 2 ! 2C 2H 4OThe feed to a reactor contains 100 kmol C 2H 4 and 100 kmol O 2. If the reaction proceeds to completion, how much of the excess reactant will be left; how much C 2H 4O will be formed; and what is the extent of reaction?
You have a lot of paperwork laying around. A ream of stacked paper is 500 sheets and is 2.0 inches thick. Let's say you had a mole of paper. (1 mole of paper = 6.022 x 1023 sheets of paper) and it was all stacked up in 10 stacks of equal height, each containing a tenth of a mole of sheets. The ten stacks sit one on top of the other. How high are they? (Hint: find the height of a stack of containing 0.1 mole of paper. USE DIMENSIONAL ANALYSIS!) Here are are some conversions you might need: 2.54 cm = 1 in; around 9.46 x 1015 meters / light yr and 3.26 light yr / parsec.
