Help me find how many moles

H 13.8mol CO2

Explanation:

we know that per 1 mol there is 6.022x10^23 molecules

so divide 8.23x10^22/ AVG # ( # above) we get 13.8mol of CO2 not to be confused with A

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 forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
