We’ll try out the second method on this new equation. You can take my word for it, or give it a try and see how long it’ll take you to balance this equation by inspection. However, it gets taxing when you encounter more complicated equation like this: C 6H 5F + O 2 → CO + H 2O + F 2. This is a rather popular method and it works pretty well to a certain extent. Since we added a 2 in front of NaCl, our Na on the right-hand side is no longer balanced, so we’ll need to add a 2 in front of NaF as well. So, we’ll place a 2 in front of NaCl like this: Looks like it’s not balanced since there’s one on the left but two on the right. Na is balanced since there is one on the left-hand side and one on the right-hand side. You balance the equation by inspecting it. Personally, I prefer Method 2 when it comes to solving easy to intermediate equations because it is simple and doesn’t tax my brain too much. There are 3 methods in mastering this art. If you count the number of atoms on both sides, you’ll notice that they are not equal: The compounds on the left-hand side (before the arrow) are called reactants while the compounds on the right-hand side (after the arrow) are called products. So the main goal of balancing chemical equation is to get the number of atoms to be the same on each side of the equation. You’ll be able to get the molar ratios for all the compounds involved in the reaction and that will enable you to perform various types of calculations correctly (more on that in future posts). Jokes aside, being able to balance chemical equation will open up a lot of possibilities. Is it important to be able to balance chemical equations correctly and quickly? You bet! Why so? First of all, you’ll make your chemistry teacher happy and maybe impress someone else along the way.
