In which case is a process spontaneous at any temperature? delta H : Negative delta s : Positive 6. For the reaction: C3H8(g) + 5O2(g) ->3CO2(g) +4H2O(l) Calculate the delta G at 298K given the delta G, KJ/mol of C3H8(g)=-23.47; O2=0; CO2=-394.4; H2O(l)=-273.13 The answer: -2155 KJ 7. In an electrochemical cell, Q=0.0010 and K=0.10. Which is true of Ecell and E^ocell? The answer: Ecell is positive and E^o cell is negative
Write the balanced 1) molecular, 2) total ionic, 3) net ionic reactions, and identify the spectator ions for the following: sodium sulfate(aq) + strontium nitrate(aq) -->
The combustion of pentane with oxygen is a well known process. Write a balanced equation for the reaction of pentane, C5H12, with oxygen, O2, forming the products carbon dioxide, CO2, and water, H2O. What mass of carbon dioxide will be produced by..
Kinoprene is an insect hormone. Derivatives of this type of compound have the potential of being highly selective, and non toxic (to us and non target animals) insectisides. Research in this area may bring about a new "green revolution",
