47. + Law of Conservation of Matter: Matter cannot be created or destroyed. AMOUNT OF REACTANTS = AMOUNT OF PRODUCTS ! ! ! !

48. + Guidelines for Balancing Chemical Equations: 1) Do NOT change the subscripts ! 2) Every element MUST have the same amount of atoms on both sides of the equation. 3) To balance, coefficients (numbers) are added in front of the chemical formula until we have the same atom amount on both sides of the equation. 4) Once a coefficient is added, go back and check the rest of the equation5) Balance every element EXCEPT Hs and Os. Then balance Hs, Os are balanced last. 6) CHECK EQUATION TO BE SURE EVERYTHING BALANCES/CANCELS OUT ON BOTH SIDES ! ! !
