Explanation;
Writing scientific notation :
- Move the decimal to the left side until single digit of number remains before the decimal.
- Then we will count the number of times we moved the decimal. Write this number as the exponential power of number '10'.
- For Example:
Radius of the sun = 696,000.0 kilometer
Radius of the sun can also be written as = 
Size of bacterial cell = 
millimeter
Size of bacterial cell can also be written as = 
The major group of organic chemicals that has double the number of hydrogen atoms as carbon or oxygen atoms [chemical formula (ch2o)n] is carbohydrates.
<h3>What are carbohydrates?</h3>
Carbohydrates are biological macromolecules that function as macronutrients by providing energy, which are composed of simple carbon-based molecules linked by glycosidic bonds.
In conclusion, the major group of organic chemicals that has double the number of hydrogen atoms as carbon or oxygen atoms [chemical formula (ch2o)n] is carbohydrates.

Gas -- move very independently as compared to a liquid, for instance.
Plasma -- related to a gas although it has positively charged ions and negatively charged electrons.
<span>The key difference between Mendeleev and modern periodic table is that Mendeleev’s periodic table was based on the increasing atomic masses while the modern periodic table is based on the increasing atomic numbers. Let us see here what is Mendeleev periodic table and what is modern periodic table, and then compare both to understand the difference between both periodic tables. Mendeleev is the pioneer of the modern periodic table, though a numerous number of changes had been made to the old version of the periodic table. Both of these attempts are equally important to the scientific community; because without an invention of the periodic relationship in elements, the modern developments in Science would not reach a development era as today. Before the invention of Mendeleev’s classification, there were several attempts made by several chemists, but their periodic laws were inadequate to apply for all the elements. The modern periodic table is so advantageous for the development in the Science.</span>
