Balancing formulas and other stuff

AS USUAL I GET THE HARD BLOG AGAIN....anyways today we learned about balancing formulas

First of all before you go balancing and telling everyone your a pro at it, we should remember something we learned.  In the equation we have 2 sides.  We HAVE to make it equal or else its entirely bs.  Why you may ask? Because according to the law of conservation matter is never evar destroyed evar.

ok lets get to the learning...or review....mostly review.  Anyway  to balance the equation you must make sure that all the atoms on one side equals the number of atoms on the other side.  There is no cleverly developed way to do this.  The way to do this is by your preference.  I, however like to balance whole groups first (eg OH, SO4, CO2) then balance the atoms in their elemental form (eg O2, K, P4).  Then CHECK CHECK CHECK to make sure both sides are balanced or else you messed up and have to waste over 10 minutes to do it again HAH!  Ms.Chen said i didnt have to go into super tryhard details since this is review so this will have to do, to jog your memories kthxbai.


note how both sides equal to each other.  He added a 2 to H2 on the left side and added a 2 to H20 on the right side
