Answer: OB
Explanation:
The empirical formula of an element is the simplest formula of an element which shows the ratios of atoms of the each element present in a molecule of a compound .
High temperature and low pressure<--Most likely
Low temperature and high pressure<----Less likely.
So the answer to this is Low temperature and high pressure.
The boiling points of alkanes increases with increasing number of carbons. This is because the intermolecular attractive forces, although individually weak, become cumulatively more significant as the number of atoms and electrons in the molecule increases.
So therefore your answer choice will increase. (B)
The correct way to write this number in scientific notation : 6.022 x 10²³
<h3>Further explanation
</h3>
Scientific Notation is a standard form of writing numbers used in mathematical operations
The rules:
1. Writing order : first digit, decimal point, next digit
2. Then followed by powers of 10 (the value can be +/-)
If the value is> 10 (the power of 10 is +), the decimal point is moved to the left, to the right of the first digit
If the value is <10 ((the power of 10 is -), the decimal point is moved to the right, to the right of the first digit
I certainly didn't count the details of the number of zeros listed, but only saw the answer choices.
And the right ones are: 6.022 x 10²³
