calculate the enthalpy of the solution in kJ/mol when 16.0g of ammonium nitrate dissolves in 100cm3 of water. (Give answer to 3sf)

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 answer would be a

the answer is 75.0%.
