What volume of 0.1 M KMnO4 would be required to titrate 0.56 g of K2[Cu(C2O4)2] • 2H2O?
Hydrogen gas is contained in a one-liter vessel at "STP"(0 degrees Celsius and 1 Std. Atm.). Flourine gas is contained in a second one-liter vessel at the same conditions of temperature and pressure.
A solvent for an industrial process requires the use of phenol or benzene. Both are about the same in effectiveness for the process, and of course, gloves will be used when handling either solvent
Compute the change in temperature when 1.8 g of sodium chloride is dissolved in 300.0 mL of water initially at 20C. The heat capacity of water is 4.184 J/mL/K.
Explain how mass effects act to lower the carbonyl frequency, as well as how inductive and hyperconjugation effects act to raise the carbonyl
A white solid remains in centrifuge tube after acetone extraction-it fizzes when hydrochloric acid is added suggesting sodium carbonate was formed- How did it form? Write a balanced equation for the formation?
A compound of forumula C14H12 gave a positive Baeyer test and burned with a yellow, sooty flame. Treatment with ozone followed by hydrolysis in the presence of zinc gave formaldehyde as one of the products.
