Chemical Change: Identify and apply types of chemical reactions

• Identify and write down combination, decomposition, and displacement reactions with reference to industrial gases (7):
  • Range: Combination reactions are metal +[latex]\scriptsize \displaystyle {{\text{O}}_{\text{2}}}[/latex], non-metal +[latex]\scriptsize \displaystyle {{\text{O}}_{\text{2}}}[/latex], metal + non-metal, metal oxide + H₂O, non-metal oxide + H₂O. Decomposition reactions are metal oxides, carbonates, nitrates, chlorates and H₂O₂ decomposing in heat. Single-displacement reactions are halogen + halide, metallic salt + salt, metal + acid, metal + H₂O –activity series).

By the end of this unit you will be able to:

• identify the following types of chemical reactions:
  • Combination
  • Decomposition
  • Single displacement.
