A mixture of 4 gases A, B, C, and D have a total pressure of 825.3 mmHg. If the partial
pressure of gas B is 452.2 mmHg, and the partial pressure of gas C is 210.3 mmHg, and the partial pressure of gas D is 98.2 mmHg. If you have 2.35 moles of gas A How many moles of gas B are present?

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.  

i think its 100.

hope this !
