Balancing Chemical Equations
STEP 1 Check all molecular formulas and make sure they are neutral, then count the atoms on both sides of the equation
STEP 2 Balance elements in the following order: NM, M, Poly, H, O
STEP 3 When balancing the polys treat them as one unit if they appear on both sides of the equation.
STEP 4 About element subscripts: If there is an odd on one side and an even on the other, put the odd number in front of the even.
STEP 5 Count all atoms on both sides of the equation and make sure they are equal.
Helpful Hints Combustion equations sometimes start with a 2 as the coefficient of the hydrocarbon. Never begin with balancing H or O!!
YOU ARE BALANCED!!
Balancing Equations I can demonstrate how mass is conserved during a chemical change.

Chemical Reactions. Learning target: I can balance chemical equations. Why learn this? This concept introduces you to the idea that matter is not created.
Balancing Chemical Equations. Balancing Act Atoms are not CREATED or DESTROYED during a chemical reaction. Scientists know that there must be the SAME.
Balancing Equations. Chemical Reaction A chemical reaction is the process by which atoms of one or more substances are rearranged to form different substances.
Balancing Equations. Balancing chemical equations is necessary so that they obey the law of conservation of mass. Remember, in Ch. R, atoms are not created.
