Balancing EquationsBalanced EquationA 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
Steps for Balancing Equations:Write skeleton equation
Use coefficents to balance the equation NEVER, EVER change subscripts.EVER!!!
Recheckshould be in lowest ratioDiatomic Atoms - HONClBrIFAtoms that covalently bond with themselves
You need to know these for balancing equations!
Example H2 + O2 H2O
# H:
# O: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
