Watch this Khan Academy video about balancing equations:
You may use headphones, or you can watch the video and read the subtitles.
Visit the following website: https://www.webqc.org/balance.php
Attempt to balance the equations then check your work by clicking on the link. Be sure to write your
work down so that you can hand it in. Please be honest and attempt to do these, then check your work.
That is where learning happens.
Then you should attempt to do the problems that are attached. This document is uploaded to Schoology
