Soil vapor extraction (SVE) is used to remove volatile or-ganic pollutants, such as chlorinated solvents, from soil at haz-ardous waste sites. Vent wells are drilled, and a vacuum pump is applied to the subsurface. (a) How does this remove pollutants?(b) Why does heating combined with SVE speed the process?

Nitroglycerine ( C3H5N3O9) is a very strong explosive that degrades over time and is too shock sensitive to transport safely. Dynamite is made by combining nitroglycerine with stabilizers and adsorbents, which makes it much safer to use. The explosion of nitroglycerin can be represented by: 4C3H5N3O9(l)→6N2(g)+12CO(g)+10H2O(g)+7O2(g) A stick of 40% dynamite is about 20 cm long and about 3 cm in diameter and weighs 203 grams. It is 40.0% nitroglycerine by mass. What is the total number of moles of gas produced when a stick of 40% dynamite explodes?

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.
Butane gas, C4H10, is sold to campers as bottled fuel. Its density at 25C and 1.00 atm is 2.38 g/L. What volume of butane gas at 25C and 1.00 atm is required to heat one gallon of water (d=1.00g/mL) from 25C to 98C ? The reaction for the combustion of butane (H f =125.6kJ/mol) is C4H10(g)+132 O2(g)4CO2(g)+5H2O(g)
Octasulfur(S8) is the most common allotrope of sulfur and is widely used in the chemical industry, especially in the production of petroleum. While S8 is the main component of elemental sulfur on earth is can also be produced in the laboratory from the reaction of sulfur dioxide with hydrogen sulfide. The balanced chemical equation for this reaction is shown below: 8SO2(g)+16H2S(g)-----3S8(s)+16H2O(g) Consider the reaction of 93.0 grams of SO2 with 93.0 grams of H2S to answer the questions below. A. What is the limiting reagent? B. What is the excess reagent? C. How many grams of S8 can be formed? D. How many grams of excess reagent are left over?

Holiday cookies rise (get bigger) when baked in the oven at 350oF because: a. sodium aluminum phosphate (Na Al PO4) releases an acid that forms CO2 gas from sodium bicarbonate (Na+ HCO3-) b. the Maillard reaction hydrolyzes wheat gluten in the batter c. yeast ferment sugar (sucrose) in the batter to form CO2 at temperatures above 72oC d. oxygen (O2) is needed to support the growth of lactic acid bacteria added to the batter e. the amount of sucrose sugar added to Holiday cookies could make reindeer fly
Thermochemistry and Stoichiometry
Long-term space missions require reclamation of the oxygen in the carbon dioxide exhaled by the crew. In one method of reclamation, 1.00 mol of carbon dioxide produces 1.00 mol of oxygen, with 1.00 mol of methane as a by-product. The methane is stored in a tank under pressure and is available to control the attitude of the spacecraft by controlled venting. A single astronaut exhales 1.03 kg of carbon dioxide each day. If the methane generated in the recycling of three astronauts' respiration during one week of flight is stored in an originally empty 140-L tank at −45.0°C, what is the final pressure in the tank?
