Single replacement reactions Element + compound → new compound + element magnesium + iron chloride  magnesium chloride + iron Lithium bromide + chlorine ↣ lithium chloride + bromine

What is special about single replacement reactions? Only more active elements can replace Use Activity Series charts Metals Halogens Use Reference Tables

magnesium + iron chloride  magnesium chloride + iron

Lithium bromide + chlorine ↣ lithium chloride + bromine

Practice: magnesium + iron nitrate  magnesium nitrate + _____________ Nickel + ______________  nickel ll sulfate + zinc zinc + ___________________  zinc II sulfate + copper zinc + iron chloride  ____________ + ____________

Predicting products – Synthesis reactions

Predicting products – decomposition reactions

Predicting products – single replacement

Predicting products – Double replacement

Predicting products: combustion
