Why do we use an ethyl acetate/hexane mixture as a solvent in reaction of cyclopentadiene with maleic anhydride, rather than just pure hexane or ethyl acetate?
Write the cell notation for the voltaic cell that incorporates eachof the following redox reactions.
hydroxylamine is titrated to the equivalence point with 35.8 m of .15 M HCl. What is the pH at the equivalence point?
A stock solution is prepared by adding 22 mL of 1 M Na3PO4 to enough water to make 73 mL. What is the PO43- concentration of 30 mL of the stock solution?
Assuming that the total pressure of the gases is 1.52 and that their mole ratio is 94 : 4.0 : 1.5 : 0.50, calculate the partial pressure (in atmospheres) of each gas.
Someday, cars may be powered by clean H2/O2 fuel cells and electric motors. Under standard conditions, such a fuel cell can develop 1.229 volts. If the oxygen is obtained from air (at P=0.21 bar), what pressure of H2 would be required to develop 1..
