From the values given for delta H and delta S , calculate delta G for each of the following reactions at 298K?
Q. 1) 2PbS(s) + 3O2(g) -> 2PbO(s) + 2SO2(g) Delta H = -844kJ; Delta S = -165J/K Is it spontaneous? 2) 2POCl3(g) -> 2PCl3(g) + O2(g) Delta H = 527kJ; Delta S = 179J/K Is it spontaneous?

A. Convert the unit of Delta S(J/K) into kJ/K...165 to 0.165 1) Delta G=Delta H -Delta S(T) Delta G=-844 -(-0.165)(298) =so,got the answer,if G is negative,it will be spontaneous,if positive, it 's non spontaneous the way to solve the number 2 is the same like first..

What is the delta charge on the carbon atom in ClCH3? Polarity?
Q. I was told the carbon has a delta positive and delta negative charge, I don't get why this is. Please explain why carbon has both delta +ive and -ive charges that cancel out? What is the overall delta charge on the carbon!!
