How do I balance chemical equations fast?
Can you give me an example?
Sure! Let's balance the equation: Fe + O2 -> Fe2O3. To start, we see that iron (Fe) appears only once on each side, so we can leave it balanced. Next, we notice that there are two oxygen (O) atoms on the right side and only one on the left. We can balance this by putting a 2 in front of Fe on the left side: 2Fe + O2 -> Fe2O3. Finally, we balance the number of Fe atoms by putting a 2 in front of Fe2O3 on the right side: 2Fe + O2 -> 2Fe2O3.
