A sample of a solid of 29.19 grams is placed in a flask. Toluene is added to the flask (Toluene, in which the solid is insoluble,) total volume of liquid and solid together becomes fifty milliliters. The toluene and solid together weigh 55.81 grams. Determine What would be the density of the solid if density of toluene at the temperature of the experiment = 0.864 g/mL.?
The reaction of 2,2-dimethyl-1-propanol with HBr is very slow and gives 2-bromo-2-methyl-propane as the major product. Give a mechanistic
While in Europe, if you drive 109 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per liter and your car's gas mileage is 29.0 mi/gal? Assume that 1euro=1.26 dollars.
want to synthesize 3-methyl-2-pentene from 2-chloro-3-methylpentane. Which reagent would you use
A 0.28 mol sample of a weak acid with an unknown pKa was combined with 12.0 mL of 3.10M KOH and the resulting solution was diluted to 1.500 L.
A 1.000-mL aliquot of a solution containing Cu2 and Ni2 is treated with 25.00 mL of a 0.03632 M EDTA solution. The solution is then back titrated with 0.02254 M Zn2 solution at a pH of 5. A volume of 18.39 mL of the Zn2 solutio..
Compression and Cooling of Nitrogen Gas. A volume of 65.0 ft^3 of N2 gas at 90°F and 29.0 psig is compressed to 75 psig and cooled to 65°F.
he worked up the reaction and isolated 2.4 g of MnCl2. What was his percent yield?
Based on the stereochemistry of the addition of bromine to cinnamic acid, write structure of the dibromide product(s) that you think will be formed as the result of the reaction of Z-2-pentene with bromine
I did three trials and my volumes for the sodium thiosulfate were 12.5 ml, 11.1 ml, and 10.2 ml. I am not sure how to get the molarity of the sodium thiosulfate secondary solution for each trial from this information.
Draw a circuit diagram that subtracts two inputs signals and then amplifies the subtracted signal
The Ksp of tin(II) hydroxide, Sn(OH)2, is 5.45 × 10-27. Calculate the solubility of this compound in g/L.
Aspirin is a monoprotic acid called acetylsalicylic acid. Its formula is HC9H7O4. A certain pain reliever was analyzed for aspirin by dissolving 0.431 g of it in water and titrating it with 0.0430 M KOH solution.
