If the total mass of H2O produced is 23.4 grams, what was the approximate mass of the methane in the original mixture?
Hydrogen is collected over water at .975 atm and 28 degrees Celsius. What is the partial pressure of H2?
What is the mass percent of sucrose (C12H22O11, Mm=342 g/mol) in a 0.350-m sucrose solution?
An excess of aluminum foil is allowed to react with 225 mL of an aqueous solution of HCl (d = 1.088 g/mL) that contains 18.0% HCl by mass.
To 1.00 L of a 0.100 M aqueous solution of benzoic acid (C6H5COOH) is added 1.00 mL of 12.0 M HCl. What is the percentage ionization of the benzoic acid in the resulting solution? [Ka(C6H5COOH) = 6.5 × 10-5]
Calculate the theoretical yield of C2H5Cl when 106 g of C2H6 reacts with 236 g of Cl2 assuming that C2H6 and Cl2 react only to form C2H5Cl and HCl
Propose a reasonable synthetic strategy for the synthesis of trans-6-methyl-3-heptene from 4-methyl-1-pentyne.
Aspirin (C9H8O4) is produced through the following reaction of salicylic acid (C7H6O3) and acetic anhydride (C4H6O3). C7H6O3(s) + C4H6O3-> C9H8O4(s) + HC2H3O2
Consider equal volumes (say 1 rm L) of a substance in the solid, liquid, and gas phases. Arrange them in order of decreasing mass. If the mass difference between samples is relatively small, rank the items as equivalent.
