Calculate the number of pounds of CO, released into the atmosphere when a 13.0 gallon tank of gasoline is burned in an automobile engine. Assume that gasoline is primarily octane, C,H,2, and that the density of gasoline is 0.692 g mL-. This assumption ignores additives. Also, assume complete combustion. CO, released: lb - TOOLS x10

Commercial concentrated hydrochloric acid has the following specification: Density = 1.2 g/mL; Weight percentage is 37% w/w: Molecular weight of HCl is 36.46 g/mol. If 12.0 mL of conc HC) is added to the reaction, how many moles of HCI have been added? Report your answer to the correct number of significant figures: do not report the units in your answer.OGMU 2020 QUESTION 3 If 5.0 mL of t-pentyl alcohol are involved in the reaction, how many moles of t-pentyl alcohol are present? Round your answer to the correct number of significant figures. Do not include the units in your answer. IUPAC name of t-pentyl alcohol is 2-methyl-2-butanol.OGMU 2020 (Hint: use the CRC Handbook Of Chemistry and Physics from our online library to get the correct numerical constants.) QUESTION 4 Given that the nucleophilic substitution reaction used 5.0 mL of t-pentyl alcohol and 12.0 mL of conc. hydrochloric acid to produce t-pentyl chloride, what was the limiting reagent in the overall reaction?

Acetylene torches are used for welding. These torches use a mixture of acetylene gas, C2H2C2H2, and oxygen gas, O2O2 to produce the following combustion reaction: 2C2H2(g)+5O2(g)→4CO2(g)+2H2O(g)2C2H2(g)+5O2(g)→4CO2(g)+2H2O(g)     Part A Imagine that you have a 7.00 LL gas tank and a 4.50 LL gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch. If you fill the larger tank with oxygen to a pressure of 125 atmatm , to what pressure should you fill the acetylene tank to ensure that you run out of each gas at the same time? Assume ideal behavior for all gases. Express your answer with the appropriate units.

One commercial system removes SO2 emissions from smoke at 95.0°C by the following set of balanced reactions:                SO2(g) + Cl2 → SO2Cl2(g)               SO2Cl2 + 2H2O → H2SO4 + 2HCl               H2SO4 + Ca(OH)2 → CaSO4(s) + 2H2O Assuming the process is 0.86 % efficient, how many grams of CaSO4 may be produced from 91 g of SO2? Report your answer to 3 sig figs.
