The addition of H2 to C=C double bonds is an important reaction used in the presentation of margarine from vegetable oils. If 50.0ml of H2 and 50.0ml of ethylene (C2H4) are allowed to react at 1.5atm, the product ethane (C2H6) has a volume of 50.0ml. Calculate the amount of PV work done, and tell the direction of energy flow...... C2H4(g) + H2(g)---------C2H6(g)
Hemoglobin is the protein that transports oxygen in mammals. Hemoglobin is 0.342% Fe by mass, and each hemoglobin molecule contains four iron atoms. Calculate the molar mass of hemoglobin
