1.00 mole Mg
1.00 mole Mg

1.50 moles Mg
1.50 moles Mg

2.00 moles Mg
2.00 moles Mg

3.00 moles Mg

your answers are a,b,,e and f

i hope this

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.  

answer: you could do some invislibe ink.

explanation: i will tell you how to if u answer my question.
