Calculate the number of moles
56.75 g of al(no3)3
8.35 g of al2(so4)3
3.8 g of feso4

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.  

58750.08068 is the answer i think

the answer is barium and copper bromide
