(35 pоints tоtаl) Dr. Grubbs is аgаin dоing the stoichiometry balloon demo. This involves the combustion of hydrogen to give water. a. (10 points) Write the balanced molecular reaction and identify the oxidizing and reducing agents. b. (20 points) Considering ideal gas behavior and that only the contents of the balloon react, calculate the mass of water produced from Dr. Grubbs filling a 5.00 L balloon with 1.00 atm of hydrogen and 1.00 atm of oxygen in his lab kept at 23°C. c. (5 points) Identify the limiting and excess reactants in the demo.
