The equation balanced is:
2 FeCl₃ + 3 MgO → Fe₂O₃ + 3 MgCl₂
Equation balancing can be done by "trial and error" or by algebraic method.
In this way the equation is balanced on both sides having:
2 atoms of Fe, 6 of Cl, 3 of Mg and 3 of 0.

Answer:
In general, atomic radius decreases across a period and increases down a group. ... Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital. This results in a larger atomic radius.
