- Hey, Klide! Can you teach me about the thing with magnesium again? The one where it uhh... reacts with nitro-tri-thingy?
- Ah yes! That one!
- Sure!
- You mean the one where magnesium reacts with nitrogen gas to produce magnesium nitride?
- Neat! Thanks for teaching me that, Klide!
- No problem, Mark!
- And voila! Now we have a balanced chemical equation!
- Hey Klide, why is it called an unbalanced equation?
- It is called an unbalanced equation because there are UNEQUAL numbers of atoms on each side of the arrow. A balanced equation, however, means that there are the same number of each type of atom on both sides of the arrow.
- Okay, so how do we turn it into a balanced equation?
- Well first we have to count the number if different atoms on the reactants' side and the product's side and if it unbalanced, we need to use coefficients which are numbers we use (in this case) in front of the substances reacting to balance the equation.
