1
Double displacement reaction
A + B → AB
AB → A + B
AB + CD → AD + CB
A + BC → AC + B
2
When applied to balancing equations, the law of conservation of mass tells us that the
mass of the products will never equal mass of the reactants.
mass of the products will always be more than the reactants.
mass of the reactants will always be more.
# atoms of an element must be = for products & reactants.
