Answer:
B. Ionic Compound
Explanation:
An ionic compound is that compound which contains a positively charged ion called CATION and a negatively charged ion called ANION. The cation loses or transfers electrons to the anion, hence, making the former (cation) positive and the latter (anion) negative.
A polyatomic ion is an ion that contains more than one type of atom e.g OH-, NO3²-, CO3²- etc. A polyatomic ion usually has an overall charge formed from the charges of the individual atoms that makes it up. For example, in OH-, the overall charge is -1.
Since a polyatomic ion can have an overall positive or negative charge, it must enter a reaction with another ion that complements it i.e. a negative polyatomic ion will react with a positive ion to neutralize its charge. Hence, this forms an IONIC COMPOUND. This is why most compounds with polyatomic ions are IONIC COMPOUNDS.
For example, CaCO3 is an ionic compound formed when Ca²+ (cation) reacts with the polyatomic anion: CO3²-
Answer : The number of moles of aluminium oxide produced from 0.35 moles of oxygen are, 0.233 moles.
Solution : Given,
Moles of oxygen = 0.35 moles
The balanced chemical reaction will be,

From the balanced chemical equation, we conclude that
As, 3 moles of oxygen react to give 2 moles of aluminium oxide
So, 0.35 moles of oxygen react to give
of aluminium oxide
Therefore, the number of moles of aluminium oxide produced from 0.35 moles of oxygen are, 0.233 moles.
The chemical formula will be
.
<h3>Chemical formula</h3>
From the model, there are a total of 4 carbon atoms, 9 hydrogen atoms, and 2 oxygen atoms.
All the atoms are bonded to each other accordingly.
Thus, the only plausible chemical formula for the compound is 
All other available options fall short in one way or the other as far as the number of atoms of each element in the compound is concerned.
