Balanced equation
Solution
Reaction
Fe + O₂⇒ 2Fe₂O₃
For a simple equation where one of the reaction coefficients is known, we can immediately add the corresponding coefficient using the principle that the number of atoms of the components in the reactants and products is the same.
In the above reaction :
Fe, left=1, right = 4, so coefficient in the left=4
O, left=2, right = 6, so coefficient in the left=3
