ratio

Why do you need to balance a chemical equation to find out the ratio of the number of moles between products and reactants?

You need to balance them because it shows that everying is equal. If you didn't then you would have it all messed up because they aren't the same. Once you get an equation balanced then you can determine the ratios.

This way you can show that they are equal. If you don't the conversions won't be right. Once the equations are balanced you are able to determine ratios.

You need to balance chemical equations to show that everything is equal. You don't want them to be different. You can determine the ratios one they are balanced.

You need to show that everything is equal. If they dont equal it means that something went wrong. When the equation is balanced you can then get the ratios.
