How many molecules of triclosan are in a tube of toothpaste?
which one has the larger standard entropy value at 25C(assume thesame molar amount in the comparison) explain the reason why
A 35.0 g sample of a nonelectrolyte was dissolved is 680. g of water. The solution's freezing point was -2.80°C. What is the molar mass of the compound?
A colorless liquid A (C3H6O) was soluble in water and ether, and had a boiling point of 94-96 degrees Celsius. It decolorized a Br2-CH2Cl2 solution and gave a positive ceric nitrate test
Calculate the experimental percent by mass of copper in the sample and the theoretical mass percent of copper in copper (II) acetate monohydrate.
Compound A, C8H10, absorbed 3 equivalents of H2 on catalytic hydrogenation over a Pd/C catalyst to give B (C8H16). On ozonolysis, compound A gave, among other things, a ketone which was identified as cyclopentanone.
What is the equilibrium expression for the following reaction. Please interpret as an equilibrium symbol.
