If oxygen reacts with iron, then both must be reactants and rust the product of that reaction
4Fe → 3O2 + 2Fe2O3
We see that the equation balances
There are 4 atoms of Iron (Fe) on the left and 2*2 = 4 on the right.
3 * 2 = 6 of oxygen on the left and 2 * 3 = 6 on the right.
answer: option (b) is the correct answer.
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.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
which of these equations shows rust, fe2o3, forming when oxygen, o2, reacts with i...
