  1. Balancing Equations

  2. Balanced Equation • A chemical equation in which both sides have the SAME # of ATOMS • Remember from Dalton that mass must be conserved! • Atoms are rearranged in a chemical reaction

  3. Steps for Balancing Equations: • Write skeleton equation • Use coefficents to balance the equation NEVER, EVER change subscripts….EVER!!! • Recheck…should be in lowest ratio

  4. Diatomic Atoms - HONClBrIF • Atoms that covalently bond with themselves • You need to know these for balancing equations!

  5. Example H2 + O2 → H2O # H: # O:

  6. More Examples: AgNO3 + H2S → Ag2S + HNO3 Zn(OH)2 + H3PO4 → Zn3(PO4) 2 + H2O hydrogen + sulfur → hydrogen sulfide iron (III) chloride + calcium hydroxide → iron (III) hydroxide + calcium chloride
