Balance equations hmm. It's funny, how do you attempt to solve these problems? Believe it or not, I use ALGEBRA to solve these. It takes a little longer, but it's always right and there's no need for trial and error.

I can attempt to explain it to you or https://www.youtube.com/watch?v=ORK4eeKZaYg

I hope you watch it, because balancing equations will actually seem fun, or it did for me, once I learned it that way. Too easy.

Drop any questions if you have any.

Thank you so much, you are such a big help @dtan5457  !! I will most definatly watch it

Good! Your balance question here may be able to be solved with a couple tries, but that method the video shows will be able to balance any equation, no matter how many elements, compounds, etc. I couldn't balance equations without that video...

Now I'm free of worry of any balance question :)
