Alchemists have claimed him as one of their own. He introduced into Greece the gnomonthe sundial and cartography. He spent some time as a member of the Pythagorean community at Croton. Zeno was his eromenos.
Is the equation balanced? No, the equation is not balanced because the numbers of the atoms are not the same in the reactants and products. How could we balance the reaction? Three possibilities Plans A, B and C are given below. You must evaluate each plan, and say if it is allowed or not.
Plan A Is this change allowed? Reason Add one Fe atom on the reactant side. Change O2 to O3 on the reactant side of the equation. Changes made Is this change allowed? Yes The Fe atom is already a reactant. No Changes to formulae are not allowed.
Convert the picture equation above to a chemical equation. Remember that this is allowed. Did any formulae change, or were any new formulae added? Remember that this is NOT allowed. What do you think: Can this plan work?
No, because a formula was changed. Plan B Is this change allowed? Add one O atom on the reactant side.
Convert the picture equation to a chemical equation. Explain why or why not. No, because adding formulae is not allowed. Plan C Is this change allowed? Reason Add three Fe atoms on the reactant side. Add two O2 molecule on the reactant side. Add one Fe2O3 on the product side.
Yes The O2 molecule is already a reactant.
Yes Fe2O3 is already a product. Yes, because none of the rules for balancing equations were broken.
Which of the three plans A, B or C helped us to balance the equation using only moves that are allowed? Plan C Are there any other plans that you can think of to balance this equation?
Learners should be encouraged to try out other possibilities. They should come to the conclusion that the reaction proposed in Plan C is the only correct one. In the next activity we will balance an equation that is much simpler, but we are not going to include all the explanations of the previous activity.
