Concept of Indices with Solved Examples
Indices - We know that 64 = 2 x 2 x 2 x 2 x 2 x 2 = 2 6 We know that 64 = 2 x 2 x 2 x 2 x 2 x 2 = 2 6 Here 2 is called the base and 6 is called the power (or index or exponent). We say that "64 is equal to base 2 raised to the power 6". Similarly, if m is a positive integer and ..

Lewis Concept of Acids and Bases - Although Bronsted-Lowry theory was more general than Arrhenius' theory of acids and bases, it failed to explain the acid-base reactions which do not involve transfer of proton. For e.g..

Lewis Acid - Base Reaction
Whenever a Lewis acid reacts with a Lewis base, a covalent bond is formed. For example, CO 2 (Lewis acid) reacts with OH - (Lewis base) to give HCO 3 - (bicarbonate ion), BF 3 (boron trifluoride) behaves as a ..

In 1938 G.N. Lewis put forward a more generalized acid-base concept. According to this concept, an acid is a species (charged or uncharged), which can accept a pair of electrons and a base is a species (charged and uncharged), which can donate a pair of elect..

Tutor is the BEST. I have learned a lot from her. I never thought algebra will become my favourate subject. All because of Tutor Vista.
Very good, Tutor was clear and guided me through the whole algebra problems
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
Looking for More Help!
