Ideal Gas Law Practice Name If you need a refresher on Ideal Gas Law, go back to your Ideal Gas Law Reading Assignment from last week! On all of the following, you'll need to make sure to convert pressures to atm and convert temperatures to Kelvin in order to be able to use the R gas constant on your equation sheet! Given: Ideal Gas Law = then P= pressure V = volume R= ideal gas consent PV=nRT namount of substance n=PV/TR P=nRT/V I = temperature V=nRT/P T=PV/nR R=PV/nT 1. What pressure is required to contain 0.023 moles of nitrogen gas in a 4.2 L container at a temperature of 20.°C? 2. Oxygen gas is collected at a pressure of 123 kPa in a container which has a volume of 10.0 L. What temperature must be maintained on 0.500 moles of this gas in order to maintain this pressure? Express the temperature in degrees Celsius. 3. How many moles of chlorine gas would occupy a volume of 35.5 L at a pressure of 100.0 kPa and a temperature of 100. °C? After determining the number of moles,…

1. The following conversion includes chemistry we have covered very recently, some chemistry from last term, and chemistry from the first chapter of this unit. Provide curly arrows and an explanation for this mechanism. Use the reagents in the order given. You do not need any other reagents. 1. NaOEt OEt 2.

COOEt COOEt Step 1 Step 2 Step 3 COOEt COOEt COOH Step 6 OH Step 4 Step 7 (racemic) cyclizes under conditions (8) OTS Step 5 Step 8 ОН OH (racemic) Frontalin (racemic) Shown above are the steps in one of the several published syntheses of Frontalin, a pheromone of the western pine beetle. From the choices provided, show the reagents and conditions by which step 3 of this synthesis might be accomplished. List the reagent(s) in order that will accomplish this transformation. No more than 4 steps are required. List your answer as a single letter (single-step transformation) or a series of letters (multi-step transformation) with no commas separating them. For example, "ab" corresponds to: 1. Eto Na+ 2. NaOH, H₂O NOTE: The order in which you list your letters matters! Reagents: a. Eto Na* g. NaCN b. NaOH, H₂O h. SOCI₂ c. H3O+, heat i. (CH3)2CuLi, ether, -78°C d. LiAlH4 j. H₂O e. p-TsCI, pyridine k. RCO3H f. Br I. H3O+ 1,024
