In the example: Fe + O2 → Fe2O3 Iron is present in one reactant and one product, so balance its atoms first. There is one atom of iron on the left and two on the right, so you might think putting 2 Fe on the left would work. While that would balance iron, you already know you're going to have to adjust oxygen, too, because it isn't balanced. By inspection (i.e., looking at it), you know you have to discard a coefficient of 2 for some higher number. 3 Fe doesn't work on the left because you can't put a coefficient in from of Fe2O3 that would balance it. 4 Fe works, if you then add a coefficient of 2 in front of the rust (iron oxide) molecule, making it 2 Fe2O3. This gives you: 4 Fe + O2 → 2 Fe2O3 Iron is balanced, with 4 atoms of iron on each side of the equation. Next you need to balance oxygen.

There is a strategy that will help you balance equation more quickly. It is called balancing by inspection. Basically, you look at how many atoms you have on each side of the equation and add coefficients to the molecules to balance out the number of atoms. Balance atoms present in a single molecule of reactant and product first. Balance any oxygen or hydrogen atoms last.

When balancing equations, you never change subscripts. You add coefficients. Coefficients are whole number multipliers. If, for example, you write 2 H2O, that means you have 2 times the number of atoms in each water molecule, which would be 4 hydrogen atoms and 2 oxygen atoms. As with subscripts, you don't write the coefficient of "1", so if you don't see a coefficient, it means there is one molecule.

How do you know the equation isn't already balanced? Because the number of atoms on each side isn't the same! Conservation of mass states mass isn't created or destroyed in a chemical reaction, so you need to add coefficients in front of the chemical formulas to adjust the number of atoms so they will be the same on both sides.

The next step for balancing the chemical equation is to determine how many atoms of each element are present on each side of the arrow: Fe + O2 → Fe2O3 To do this, keep in mind a subscript indicates the number of atoms. For example, O2 has 2 atoms of oxygen. There are 2 atoms of iron and 3 atoms of oxygen in Fe2O3. There is 1 atom in Fe. When there is no subscript, it means there is 1 atom. On the reactant side: 1 Fe 2 O On the product side: 2 Fe 3 O

Fe + O2 → Fe2O3 Note the reactants always go on the left side of the arrow. A "plus" sign separates them. Next, there is an arrow indicating the direction of the reaction (reactants become products). The products are always on the right side of the arrow. The order in which you write the reactants and products is not important.

The first step is to write down the unbalanced chemical equation. If you're lucky, this will be given to you. If you're told to balance a chemical equation and only given the names of the products and reactants, you'll need to either look them up or apply rules of naming compound to determine their formulas. Let's practice using a reaction from real life, the rusting of iron in the air. To write the reaction, you need to identify the reactants (iron and oxygen) and the products (rust). Next, write the unbalanced chemical equation:

1 Write the unbalanced equation to show the reactants and products. 2 Write down how many atoms of each element there are on each side of the reaction arrow. 3 Add coefficients (the numbers in front of the formulas) so the number of atoms of each element is the same on both sides of the equation. It's easiest to balance the hydrogen and oxygen atoms last. 4 Indicate the state of matter of the reactants and products and check your work.

A balanced chemical equation tells you the amounts of reactants and products needed to satisfy the Law of Conservation of Mass. Basically, this means there are the same numbers of each type of atoms on the left side of the equation as there are on the right side of the equation. It sounds like it should be simple to balance equation, but it's a skill that takes practice. So, while you might feel like a dummy, you're not! Here's the process you follow, step by step, to balance equations. You can apply these same steps to balance any unbalanced chemical equation...

A chemical equation is a written description of what happens in a chemical reaction. The starting materials, called reactant , are listed on the lefthand side of the equation. Next comes an arrow that indicates the direction of the reaction. The righthand side of the reaction lists the substances that are made,called products.
