sodium bicarbonate is used to counteract stomach acidity. How many moles of solid sodium bicarbonate would be needed to make 100 mL of 0.660 mol/L 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.  

the millers tale is the answer.

what is the question here. i think you messed up.
