2. Energy and Matter Energy- The ability to do work or cause change. Energy can be converted from one form to another. Ex. Light bulb http://www.clean-energy- ideas.com/articles/pros_and_cons_of_s olar_energy.html

4. Energy and Matter Free energy- the energy in a system that is available for work. States of Matter –Solid –Liquid –Gas Which has more energy?

5. States of Matter http://www.ilpi.com/msds/ref/vapor.html

6. Energy and Chemical Reactions Chemical reactions are represented by equations. Reactants- Shown on left side of equation Products- Shown on right side of equation Arrows point in which direction the equation or reaction can occur http://www.onimoto.c om/p3-2.html

7. Balanced Chemical Equation http://www.chem.ufl.edu/~itl/2045/lectures/lec_3.html

8. Energy and Chemical Reactions Exergonic Reactions- Chemical reactions that involve a net release of free energy. http://www.emc.maricopa.edu /faculty/farabee/biobk/bioboo kenzym.html

9. Energy and Chemical Reactions Endergonic Reactions- Reactions that involve a net absorption of free energy http://www.emc.maricopa.edu/faculty/fa rabee/biobk/biobookenzym.html

10. Energy and Chemical Reactions Activation Energy- The amount of energy needed to start a reaction http://www.chem.ufl.edu/~itl/2045/lect ures/lec_m.html

11. Energy and Chemical Reactions Catalysts- reduce the amount of activation energy needed for a reaction Enzymes- Class of catalysts in living things http://www.scienceclarified.com/El- Ex/Enzyme.html

12. Reduction-Oxidation Reactions Redox reactions- reactions in which electrons are transferred between atoms Reduction Reactions- A reactant gains one or more electron; negative charge Oxidation Reactions- A reactant loses one or more electron; positive charge
