In Europe, gasoline efficiency is measured in . If your car's gas mileage is 38.0 , how many liters of gasoline would you need to buy to complete a 142- trip in Europe? Use the following conversions: and .Express your answer numerically in liters.
a nugget of pure gold of 4.80 grams absorbed heat of 283 joules. if the temperature was 23.0degc initially then
If it required 27.92 mL of NaOH to reach the equivalence point, what was the concentration of the acetic acid solution?
In the laboratory, a student named Georgia weighed 5.05 grams of an unknown solid mixture containing benzoic acid, copper (II) sulfate and sand.
A researcher conducts an experiment to determine the work function of a palladium surface. She fires a laser with a wavelength of 254 nm at a certain time and observes electrons hitting a detector
Determine the bimolecular (second order) rate constant of a reaction if the initial reagent concentration decreases from 4.6900 mol/L, to 0.59400 mol/L in 13.00 seconds.
When ethane (C2H6) reacts with chlorine (Cl2), the main product is C2H5Cl, but other products containing CI, such as C2H4CI2, are also obtained in small quantities.the formation of these other products reduces the yield of C2H5CI.
A compound A (C22H27NO) is insoluble in acid and base but reacts with concentrated aqueous HCl and heat to give a clear aqueous solution from which, on cooling, benzoic acid precipitates. When the supernatant solution is made basic, a liquid B sep..
Calculate the theoretical yield of iron in the reaction of 254 g of iron (III) oxide with 25.0 g of carbon, according to the equation 2Fe2O3(s) + 3C(s)> 4Fe(s) +3CO2(g)
A student added 0.40 mL of acetic anhydride instead of 4.0 mL. Did this procedural error affect the theoretical yield of her preparation? Briefly explain.
A corrosionist pipetted a 50.00 ml sample of an unknown brine and titrated it with 37.64 ml of 0.1024 M silver nitrate solution. Calculate the ppm of salt (NaCl)in the sample.
a sample of Ringer's solution contains the following concentractions (mEq/L) of cations: Na 147, K 4 and Ca2 4. If CI- is the only anion in the solution,
When gasoline burns, it reacts with oxygen in the air and forms hot gases consisting of carbon dioxide and water vapor. How does the potential energy of the gasoline and oxygen compare with the potential energy of the carbon dioxide and water vapo..
