Objectives: To predict products – using types of reactions Warm-up: Check your worksheets from last week and make corrections where needed. Types of reactions Single Replacement Predicting products Types of reactions: Balancing chemical equations
Review: Energy & Reactions Types Reaction TypeAnalogyEndo or Exo-thermic ΔH Synthesis Decomposition Single replacement Double replacement Combustion

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 ____________ + ____________
