For the reaction ? NO + ? O2 → ? NO2 ,
what is the maximum amount of NO2 which
could be formed from 8.02 mol of NO and
18.75 mol of O2?
Answer in units of g.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

it's filtration, but this is an assumption so my apologies if i got this
