Draw the major Diels-Alder product formed in the given reaction. (All hydrogen atoms are implied. If a chiral carbon atom is attached to a hydrogen atom, you should not show the hydrogen atom but use either a wedge or dashed bond and two sticks to establish stereochemistry.)
(NH4)2Cr2O7(s) ? N2(g) + 4 H2O(g) + Cr2O3(s) If 0.95 g of ammonium dichromate is used and the gases from this reaction are trapped in a 15.0 L flask at 23 °C, what is the total pressure of the gas in the flask. What are the partial pressures of N2..
