Which of the following is NOT a common air pollutant? carbon monoxide water vapor lead particulate matter

Acetylene torches are used for welding. These torches use a mixture of acetylene gas, C₂ H₂, and oxygen gas, O₂ to produce the following combustion reaction: 2C₂ H2(g) + 5O2 (g)→4CO2 (g) + 2H₂O(g) Part A Imagine that you have a 7.00 L gas tank and a 2.00 L 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 135 atm, 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. ► View Available Hint(s) P = 48.4 Submit Previous Answers atm 巴」? X Incorrect; Try Again; 4 attempts remaining

Question 26 SHOW WORK Given the following reaction: CaC 2(s) + 2H 20 - C2H 2(g) + Ca(OH) 2(aq) Assume that you place 1.85 g of calcium carbide in excess water and collect the acetylene gas over water. Calculate the maximum amount of gas that should be produced in grams round answer to 3 decimal places omit trailing zeroes The actual volume of acetylene and water vapor collected is 810 ml at 30.5°C with a pressure of 557.524 mmHg. Calculate the actual amount of gas collected(in grams) round answer to 3 decimal places omit trailing zeroes The vapor pressure of water at 30.5°C is 32.35 mmHg. Calculate the percent yield of acetylene. round answer to 2 decimal places omit trailing zeros A Moving to another question will save this response.

Please help with question 6

How can we find the percentage? And the produced?

Calculate the volume in milliliters of 3.00 mol/L H₂SO4 required to react with 9.27 g of solid containing 32.2 g Ba(NO3)2 per 100 g of solid. Given the balanced chemical reactions.   H₂SO4→ 2H+ + SO42-   Ba(NO3)2(s) → Ba²+ + 2(NO3-)   Ba²+ + SO4²- →Ba(SO4)(s)     Could you please explain the stoichiometric ratios involved in depth/ show a step by step process with more detail. Thanks.

If a "classic" SUV features a 52 gallon (197 L) gas tank and assuming complete combustion and a molecular formula of C3H18 for gasoline, how many L of air are consumed per tank of gasoline. Recall that air is 21% oxygen and assume a density of 0.78 g/mL for gasoline.

The ______ is a mixture of gases: mostly nitrogen and oxygen, with smaller amounts of argon, carbon dioxide, and other gases.

Write a balanced equation for the following by inserting the correct coefficients (if a coefficient = 1, enter "1" in the provided box). BC13(g) + H₂O()- H3BO3(s) + HCl(g)
