M& m balancing
now count the number of each type of whole molecule.
how many he's do you have?
how many oz's do you have?
how many h2o's do you have?
***these are your new coefficients of the equation. fill them in the spaces below.
_h2 + _
_02>
h2o
now answer the following questions.
how many hydrogen candies are on the left side of the arrow?
how many oxygen candies are on the left side of the arrow?
how many hydrogen candies are on the right side of the arrow?
how many oxygen candies are on the right side of the arrow?
is the equation a balanced equation?
***you may eat your h2 + o2 → h2o candies now.
now you will do the same thing with the following equations. check with your teacher when done.
put the initial compounds in the boxes before adding whole !
