<h2>
Hello!</h2>
The answer is:
The empirical formula is the option B.
<h2>
Why?</h2>
The empirical formula of a compound is the simplest formula that can be written. On the opposite, the molecular formula involves a variant of the same compound, but it can be also simplified to an empirical formula.
We are looking for a formula that cannot be simplified by dividing the number of molecules/atoms that conforms the compound.
Let's discard option by option in order to find which formula is an empirical formula (cannot be simplified)
A.
It's not an empirical formula, it's a molecular formula since it can be obtained by multiplying the empirical formula of the same compound.
B.
It's an empirical formula since it cannot be obtained by the multiplication of a whole number and the simplest formula. It's the simplest formula that we can find of the compound.
C.
It's not an empirical formula, it's a molecular formula since it can be obtained by multiplying the empirical formula of the same compound.
D.
It's not an empirical formula, it's a molecular formula since it can be obtained by multiplying the empirical formula of the same compound.
Hence, the empirical formula is the option B.
Have a nice day!

If I understand you correctly, you should fill the gap and decide which kind og bonds <span> allows metals to conduct electricity. If so, without any doubt I can say that the metalic bonds </span><span> allows metals to conduct electricity. I'm pretty sure it will help you! Regards.</span>
Besides producing hydrogen ions in water, all Arrhenius acids have a few things in common. They have pH values anywhere from 0 up to 7, they taste and smell sour and they will turn pH paper pink, red, or orange.
<h3>What Arrhenius acids?</h3>
A substance that raises the concentration of H+ ions in an aqueous solution is known as an Arrhenius acid. Traditional Arrhenius acids are highly polarized covalent substances that dissociate in water to form an anion (A-) and the cation H+.
Aqueous Arrhenius acids have distinguishing characteristics that serve as a useful definition of an acid. Acids can turn blue litmus red, produce aqueous solutions with a sour taste, and react with bases and some metals (like calcium) to generate salts. The Latin word acidus/acre, which means "sour," is where the word acid originates.
Although the precise definition solely refers to the solute, the term "acid" is sometimes used to refer to an aqueous solution of an acid that has a pH lower than 8.
