Ok so I had the same problem!! But what you want to do first is desperate all the elements based on if it’s one capitalized letter or one with a lowercase letter. You could also take longer if you look through the periodic table for the elements. Whatever the exponent is it goes to whatever it’s after, or if it’s in parentheses, you distribute it to the numbers inside. Then you try to get all the numbers to be the same. For example, if there is 2 hydrogens and 4 hydrogens, you would want them to be the same number. This is when you multiply 2 by 2 to get four, then you do that to the other elements to balance them out!! Lmk if u need more help
