I believe the answer is: in order not to write very big or very small number values
Answer:
See the explanation below, please.
Explanation:
The elements of the periodic table that belong to the same group (each column) have similar physical and chemical properties. This is because they have the same number of electrons in their last electronic layer.
Example of electronic configuration of elements of GROUP IA:
Hydrogen: 1s ^ 1
Lithium: 1s ^ 2 2s ^ 1
A) CH4
In general, methane reactions are difficult to control. Partial oxidation to methanol, for example, is a rather difficult reaction because the chemical reactions that occur continue to form carbon dioxide and water even though the amount of oxygen available is insufficient.
<h2>Further explanation
</h2>
Methane is the simplest hydrocarbon in the form of gas with the chemical formula CH4. Pure methane does not smell, but if used for commercial purposes, a bit of sulfur is usually added to detect leaks that might occur.
Methane is a greenhouse gas. Methane is used in chemical industrial processes and can be transported as frozen liquids (liquefied natural gas, or LNG).
Methane is a major component of natural gas, around 87% of volume.
Methane is not toxic, but is highly flammable and can cause explosions when mixed with air.

In a bag of peas that weighs 454 grams, there are between 1261 and 4540 peas.
The average pea weighs between 0.1 and 0.36 grams.
If we take the lower value (0.1 g/pea), the number of peas in 454 g is:
If we take the higher value (0.36 g/pea), the number of peas in 454 g is:
