Introduction Kinetic energy is the energy one possesses due to motion. When a pendulum bob swings, it experiences a movement of displacement. The change in position as a result of little application of force, causing motion called kinetic energy. Kinetic energy (K.E) = ½ MV2 = ½ MW2 [r2 – y2] Given mass M,

Introduction Electrochemistry is the study of electricity and how it relates to chemical reactions. In electrochemistry, electricity can be generated by movements of electrons from one element to another in a reaction known as redox reaction, or oxidation-reduction reaction. In other word, electrochemistry is the study of changes that cause electrons to move. This movement

Theory of Logarithm The logarithm of a number X to a base A is the power (index) of A in X If logAX =Y, then X =AY Example: log 101000 = 3, then 103 = 1000 This rule holds for all bases, therefore if 24 = 16, then log216 = 4 TRY THIS: Express the

Introduction The most important classification in chemistry is the arrangement of the elements in the periodic table. In 1869, Mendeleev, a Russian scientist, was the first to construct a periodic table. He arranged the elements in order of increasing relative atomic mass. He pointed out that elements with similar properties kept recurring at regular intervals

Directed Algebraic Terms Remember that in algebra, letters stand for numbers. The number can be whole or fractional, positive or negative. Just as 5a is short for 5 x a, so -5a is short for (-5) x a. Just as m is short for 1 x m, so –m is short for (-1) x m.
