Explain a rigid 8.20 L flask contains a mixture of 2.50 moles of H2, 0.500moles of O2 and sufficient Ar thus that the partial mixture of Ar in the flask is 2.00 atm. The temperature is 127 degrees Celcius.
Compute the density in g L-1 of the mixture in the flask.
Two propagation steps are given below. (a) Draw the intermediate compound in the Step 2 box. (Keep Br2.) (b) Draw the appropriate curved arrows - in the Step 1 and 2 boxes - to show the mechanism of each step. See the Hint for formatting procedure..
