# Thread: Is this equation balanced?

1. ## Is this equation balanced?

Quick question: can we divide subscript or superscript numbers for balancing Chemical equations? Someone told me we could, but if you think of it practically, it doesn't make sense. How would you do that in real life?

Also, is this equation balanced: 4HCl + 2CaCO3 ----> 2CaCl2 + 2H2O + 2CO2
I checked it on a Chem equation calculator website, but it told me I was wrong.

It is technically but is not the simplest form. You can divide through by 2:

2HCl+CaCO3 ---> CaCl2 + H2O + CO2

How does division work in Chemical equations (we were never taught to divide it)? Could you explain?

When you balance the equation originally, you do it such that the smallest possible integer coefficients are in front.

Think of it like equivalent fractions. When you balance it.
