Lewis structure is a theory that helps in understanding the structure of a given compound, based on the octet rule. Every type of bond has its own bond energy and in terms of hooke's law we can also say it to have an elastic or stretchable nature. The very idea of oxidation states is not all that useful within the realm of organic chemistry, so you may just as well leave it at the door. This nature depends on the attractive forces between the atoms dictating the bond. Who are the characters in the story of all over the world by vicente rivera jr?

Problem: Determine the oxidation number (oxidation state) of each element in the following six compounds.a. There is only one answer: unique elements contained in different infinite sets -------the characteristics of their special properties, special conditions of existence, special forms, special relationships as well as very special quantitative meaning! However, studies have shown that, due to the lack of the whole “carriers’ theory” in the foundation of present classical infinite theory, it is impossible for mathematicians to study and cognize those unique characteristics of elements operationally and theoretically in present classical set theory.

Is dative bond more elastic or stretchable than covalent bond? Next is hydrogen (H), which has a preferred oxidation state of +1. Using the rule and adding the oxidation numbers in the compound, the equation becomes x +(-4 ) = 0. The sum of all oxidation states must equal the overall charge on the molecule (in this case, zero). Yes, it has an oxidation number of 0. Since CH2Cl2 is neutral, each H contributes +1, and each Cl contributes -1, we have: 0 = oxidation number (C) + 2 (1) + 2 (-1) --> the oxidation number of C is 0. It is believed that there are the bijection relationships between Infinite Natural Number Set and Infinite Rational Number Set, but following simple story tells us that Infinite Rational Number Set has far more elements than that of Infinite Natural Number Set: The elements of a tiny portion of rational numbers from Infinite Rational Number Set (the sub set ： 0, 1, 1/2, 1/3, 1/4, 1/5, 1/6, …, 1/n …) map and use up (bijective) all the numbers in Infinite Natural Number Set (0,1, 2, 3, 4, 5, 6, …, n …); so，infinite rational numbers (at least 2,3,4,5,6,…n,…) from Infinite Rational Number Set are left in the “one—to—one element mapping between Infinite Rational Number Set and Infinite Natural Number Set (not the integer set )------- Infinite Rational Number Set has infinite more elements than Infinite Natural Number Set.
