How to Balance Aluminum + Copper (II) chloride → Aluminum chloride + Copper

How to Balance: Al + CuCl2 → AlCl3 + Cu

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

Word Equation: Aluminum + Copper (II) chloride → Aluminum chloride + Copper

Balancing Strategies: This is a single displacement reaction. To balance this reaction I recommend starting with the AlCl3 in changing the coefficient to get an even number of chlorine atoms. That'll make the equation a lot easier to balance.

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.
