- The reaction of solid calcium fluoride and sulfuric acid produces calcium sulfate solids and gaseous HF. The gas product is dissolved in water to form hydrofluoric acid. Fluorite ore, a source of calcium fluoride, contains 95%wt CaF2 and 5%wt SiO2. In a certain process, the ore is reacted with 93%wt aqueous sulfuric acid, supplied 15% in excess. From this, 95% of the ore dissolves in the acid. Some of the HF formed reacts with the dissolved silica in the reaction: HF reacts with SiO2 to produce H2SiF6 and liquid water. If 60%wt of hydrofluoric acid was formed when hydrogen fluoride (which exits the reactor) is dissolved in water, determine the amount of ore needed to produce one metric ton of acid. Report your answers to one decimal place only.Acetaminophen, a popular drug taken as pain reliever and fever reducer, is produced together with acetic acid from the reaction of 3.05 g 4-aminophenol and 4.1 ml of acetic anhydride. Acetaminophen was extracted at 60% yield. Density of acetic anhydride at 20 C, 1.08 g/ml. Calculate the actual no. of grams of acetaminophen produced. [Determine L.R., E.R.]The combustion of liquid ethanol (C2H5OH)(C2H5OH) produces carbon dioxide and water. After 4.63 mLmL of ethanol (density=0.789g/ml)(density=0.789g/ml) was allowed to burn in the presence of 15.50 gg of oxygen gas, 3.70 mLmL of water (density=1.00g/ml)(density=1.00g/ml) was collected. Determine the theoretical and percent yeild of h2o in the reaction.

(Show work) How many moles of barium sulfate would theoretically be produced during this reaction? (show work) If 25g of barium sulfate were actually recovered in this experiment, what is the % yield? (Show work)Volumetric analysis of the products of combustion of an unknown hydrocarbon, measured on a dry basis, gives 10.4% CO2 1.2% CO 2.8% O2, and 85.6% N2 Determine: a): the complete actual combustion equation, with coefficients of O2 and N2 separately in the reactants, b): the composition of the hydrocarbon and tell that whether such specie exists in nature. c): the percent theoretical air. Take oxygen in air as: 23.3% by mass and 21% by mole. NOTE: Do not solve this problem in tabulated form, otherwise your answer will be considered totally wrong.Coal-fired power plants emit CO2, which is one of the gases that is of concern with regard to global warming. A technique that power plants can adopt to keep most of the CO2 from entering the air is called CO2 capture and storage (CCS). If the incremental cost of the sequestration process is $0.019 per kilowatt-hour, what is the present worth of the extra cost over a 3-year period to a manufacturing plant that uses 100,000 kWh of power per month? The interest rate is 12% per year compounded quarterly.
- In measurements made in the chimney (stack), the amount of total specific dry stack gas was measured as 11.6 Nm3/kg and the CO2 ratio in the flue gas as 12%.

We can average all of the acetic acid masses from the completely reacted samples in the previous step. For now, let's assume we ended up with a final average mass of 2.37 g acetic acid consumed. If the initial volume of acetic acid used was 50.0 mL, what's the %m/v of acetic acid?Heating MgSO4•7H2O at 150oC produces a different hydrate, MgSO4•XH2O.

- When concentrated nitric is sold, the label contains no mention of the molarity of the acid. Instead, the label normally lists the concentration of nitric acid as a wt/wt percent and gives the specific gravity of the solution. If the solution is 68.0 (wt/wt %) and nitric acid and has a specific gravity of 1.41 kg/L, calculate the molarity of 68.0 % concentrated nitric acid.
