    What fantasy universe would you live in?

    To me, it has to be the Amber world from Roger Zelazny's novels. If you'd get the same lifespan and ability to walk among shadow like the children of Oberon do, I can't imagine a more interesting world.

    Area in between graphs, one graph partially below y=0

    Sorry for the extremely late answer. Thanks for the help, after the answers I went to check again to see what I was missing, why I couldn't really see that it was both true. After working through it again I noticed that taking the negative integral of the part underneath the x-axis will turn...

    Area in between graphs, one graph partially below y=0

    Homework Statement [/B] The problem is stated in dutch and dutch is my first language. I will try to translate it all as accurately as possible. Imagine the following two functions: f(x)=x^3-4x^2 and g(x)=2x^2. Algebraically calculate the area in between the two graphs. Homework Equations...

    Shift Equlibrium Concentrations Curves w/o Adding Stress

    You can reduce the volume to shift the equilibrium, if you reduce the volume you increase the pressure so that favors the side with fewer moles of gas.

    Correct Net Ionic Equations | Eliminate Spectator Ions | Homework Help

    Which one do you then think is wrong? As a tip, try writing all of the complete ionic equation first and indicate all of the phases. Then look at which of the ions remain in the same phase to write the net ionic equation. You should be able to figure out which ones are wrong and which ones are...

    Is the Auto-Ionization of Water Exothermic or Endothermic?

    The autoionization of water is an endothermic reaction. If we increases the temperature Kw increases and the equilibrium shifts towards the products. Because an increase in temperature favors the endothermic side (the products, in this case) we can conclude that the forward reaction is...

    Shift Equlibrium Concentrations Curves w/o Adding Stress

    It depends on what you call 'stress'. For everything that increases stress you can also do the opposite, and the reaction will shift to the opposite side as well. For example: If you increase the pressure (add stress?) of a reaction, it will favor the side with fewer moles of gas. If you...
