Chlorine Gas Preparation
Chlorine gas can be prepared in the laboratory by the reaction of manganese dioxide with hydrochloric acid:
MnO2(s) + 4HCl(aq) --> MnCl2(aq) + 2H2O(l) + Cl2(g)
How much MnO2 should be added to excess HCl to obtain 275mL of chlorine gas at 5.0C and 650 mmHg?

Solution Preview
Use the ideal gas law to find the number of moles of chlorine gas.
Pressure in atm = 650 mmHg (1 atm/760 mmHg) = 0.855 atm
number of moles Cl2 = PV/RT = [(0.855 ...
Solution Summary
This complete solution uses the ideal gas law to do calculations and find the answer.
Isoprene reaction
Isoprene (2-methyl-1,3-butadiene) reacts with the following:
(1) hydrogen chloride (1 mole equivalent) in ether
(2) deuterium chloride (1 mole equivalent) in ether
(3) bromine (1 mole equivalent) in carbon tetrachloride
(4) excess hydrogen gas in the presence of a PtO2 catalyst
(5) excess mercury (II) acetate and methanol followed by sodium borohydride
(6) excess ozone followed by zinc and acetic acid
How should the structures of the obtained products from each of the reagents be drawn?
