What’s the balance?
Fe + O2 > Fe2 O3

Explain pls

Fe = 4                 O=6

O  = 6                 Fe = 4

Explanation:

Fe + O2 > Fe2 O3

4Fe + 3O2 > 2Fe2 O3

Check

Fe = 4                Fe = 4

O  = 6                 O  = 6  

This is the balance equation.

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.  

d.) circle motion requires a force to give it a centripetal acceleration.
