Monday, September-13-10 - Even group labs start next week – tutorials start today - Chapter 5 reactions in Aqueous solutions o How do reactions occur? You need to break bonds in order for reactions to occur. Any chemical reactions when you transform matter involved the breaking of chemical bonds and the formation of new bonds Increased heat is equivalent to increased kinetic energy which makes reactions occur faster [i] = concentration (chapter 5 lecture slide 2) Balanced chemical equations prove that no matter is lost or created in a chemical reaction(Law of conservation of mass) There must be the same amount of energy in the beginning of the reaction and the end of the reaction. Complete reaction means there are only products and no reactants while partial refers to that their being a mixture of both products and reactants at the end of a reaction K = equilibrium concept Rate of reaction is whether the reaction occurs fast or slow.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
