- a pharmacist added 15 g of 20% w/w calamine cream to 300g of aquaphor. what is the percent stregth w/w of the final calamine product? Show work of how to get the answer. Answer should be 0.95%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…delta Gf of H2 and O2 are zero
- a mixture of 20 cm³ of a gaseous hydrocarbon and 80 cm³ O2 is burned. Combustion products after cooling pass into KOH solution, it is noticed that a volume reduction of 40 cm³ appears. Eventually 30 cm³ gas remains. If all volumes are measured under the same conditions, find the molecular formula of hydrocarbon.Heating MgSO4•7H2O at 150oC produces a different hydrate, MgSO4•XH2O. If heating 24.4 g of pure MgSO4•7H2O at 150oC were to give 19.0505 of pure MgSO4•XH2O, what is the integer value for X?An aqueous solution of sucrose (C12H22O11) is prepared by dissolving 7.4045 g in sufficient deionized water to form a 100.00 mL solution. Calculate the molarity of the solution. Do you mind showing work? I would assume that (given) gram weight (times moles present/divided by mole(s) of compound) then divided - again by compound weight will give a percentage, then divded by the .....that's where I'm a little lost. thanks
- Calculate the values of vrms, vmp, and vmean for Cl2 (70.90 g mol-1) at 25 °CSulfur dioxide emissions from coal-based power plants areremoved by flue-gas desulfurization.The flue gas passes through a scrubber, and a slurry of wet calcium carbonate reacts with it toform carbon dioxide and calcium sulfite. The calcium sulfite then reacts with oxygen to form calcium sulfate, which is sold as gypsum. (a) If the sulfur dioxide concentration is 1000 times higher than its mole fraction in clean dry air (21010), how much calcium sulfate (kg) can be made from scrubbing 4 GL of flue gas (1 GL1X10^9L)? A state-of-the-art scrubber removes at least 95% of the sulfur dioxide.
