In a metered-dose inhaler (MDI), such as those used for asthma medication, medicine isdelivered by a compressed-gas propellant. (The device is similar in concept to a can of spraypaint.) When the inhaler is activated, a fixed amount of the medicine suspended in thepropellant is expelled from the mouthpiece and inhaled. In the past, chlorofluorocarbons(CFCs) were used as propellants; however, because of their reactivity with the Earth's ozonelayer, they have been replaced by hydrofluorocarbons (HFCs), which do not react withozone. Now HFC use is also being reduced due to their high global warming potential. In one brand of inhalers, the original CFC propellant was replaced by HFC 227ea (C3HF7,heptafluoropropane). The volume of the inhaler propellant reservoir is 1.00×102 mL, and thepropellant is charged into the reservoir to a gauge pressure of 4.443 atm at 23°C. An onlinesearch for properties of HFC 227ea yields the information that the critical temperature andpressure of the substance…

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?

Sugar Cane Solution Evaporation. Evaporator is used to thicken sugar cane solution. The feed rate is 10,000 kg / day, wherein the solution contains 25% (w / w) solid sugar. The result of thickening is that of a 65% (w / w) solution of solid sugar. Calculate the weight of the solution produced and the amount of air removed. (a) The weight of the solution produced = Answerkg (b) The amount of air removed = Answerkg
SpaceX recently launched their Falcon Heavy rocket (Feb. 6, 2018). It is based on their existing Falcon 9 rocket. The Falcon 9 rocket has a first stage which is a 40 m high by 3.7 m diameter cylinder. This cylinder contains the fuel used to propel the rocket which consists of RP-1 (rocket propellant-1, high grade kerosene), and liquid oxygen, O2 (`). RP-1 is a complex mixture of hydrocarbons but let’s approximate it with a chemical composition of C12H26. The densities of the fuel are ρ (RP − 1) = 0.83 g cm3 ρ (liquid O2) = 1.141 g cm3 If the total volume available for the two tanks is contained in the 40 m high by 3.7 m diameter first stage, determine the volume of each individual tank that will provide the exact amount of RP-1 and oxygen for the reation (no limiting reagent) and take up the entire volume of the first stage. Here are some suggestions to guide you. 1. Write a balanced combustion reaction for C12H26 with O2. 2. Determine the ratio of the volumes of the individual RP-1…
Your careless, clumsy lab mate has accidentally allowed carbon monoxide to leak out of a reactor, causing your lab’s CO monitor alarm to sound. After you quickly put on the appropriate Personal Protective Equipment, you find the leak and seal it. Then, you close your lab door, shut the windows, and call OSHA to report the hazard.When OSHA technicians arrive, they begin ventilating the 3000-ft3laboratory by pumping 25 ft3/min of fresh air into the room and removing the contaminated air at the same rate. They put a shop fan in the laboratory, such that the air is well-mixed. They also install a digital CO composition monitor, which currently reads 2 mol%. OSHA tells you that the laboratory is safe when there is less than 35 ppm of CO in the lab.How long must you wait to get back to work?
