chemistry/stoichiometry/balancing/ How to BalanceCuCl2 + Na2S = CuS + NaCl

How to Balance Copper (II) chloride + Sodium sulfide → Copper (II) sulfide + Sodium chloride

How to Balance: CuCl2 + Na2S → CuS + NaCl

Type of Chemical Reaction: This is a double displacement reaction.

Word Equation: Copper (II) chloride + Sodium sulfide → Copper (II) sulfide + Sodium chloride

Balancing Strategies: In this double dispalcement reaction the Cu in CuCl2 and the Na in Na2S are switching places.

Be sure to only change the coefficients (the numbers in front of the compounds) when balancing chemical equations.

About Balancing Chemical Equations

When balancing chemical equations our goal is to have the same number of each type of atom on both sides of the equation.

Only change the coefficients (these are the numbers in front substances).
Coefficients are the numbers in front of the molecule.
Never change the subscripts (the small numbers after elements).
Coefficients are the numbers in front of the molecule.
