In 1871, a Russian Chemist, Dimitri Mendeleev, gave a useful scheme for classification of elements. He presented the first regular periodic table in which elements of similar chemical properties were arranged in eight vertical columns called groups. The horizontal rows of table were called periods. He arranged elements in ascending order of their atomic masses and found that elements having similar chemical properties appeared at regular intervals. This observation was called Periodic Law.

Answer:
B. 3'
Explanation:
Polymerization is the process of forming large molecules by joining together many small molecules. The small molecules are known as the monomers, and the macromolecules are called polymers.
There are two(2) types of polymerization.
a. addition polymerization
b. condensation polymerization
Polymerization is characterized by eliminating small molecules such as water, carbon(IV)oxide, methanol e.t.c.
In complex compounds, polymerization starts at the 3' end of the template.
<h2 /><h2 /><h2>answer.</h2>
five oxygen molecules
step by step explanation.
according to the equation,one molecule of oxygen is enough to react with two carbon molecules thus 10 carbon molecules need 5oxygen molecules
