(a) What volume of distilled water is needed to dilute 45.0 cm³ of 0.68 g cm^-3 HNO3(aq) to 0.45 mol dm^ -3 ? (b) the diluted HNO3(aq) in (a) is left uncovered for three hours, 30.0cm³ of the HNO3 (aq) remains. What is the molarity of this solution? ​

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.  

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
