  2. Determining Types of Reactions • Synthesis – 1 product • Decomposition – 1 reactant • Single displacement – 1 element & 1 compound react to produce a different element & a different compound • Double displacement – 2 compounds react to form two different compounds. • Neutralization – acid and base in the reactants & water as one of the products. • Combustion – O2 as a reactant & CO2 and H2O as the products.

  3. Determining the type of reaction • Synthesis – two or more reactants and only 1 product. • H2(g) + O2(g) H2O(l) • Na(s) + Cl2(g) NaCl(s)

  4. Determining the type of reaction • Decomposition – only 1 reactant and 2 or more products. • 2 HgO(l) 2 Hg(l) + O2(g) • NaHCO3(s)Na2CO3(s)+ H2O(l) + CO2(g)

  5. Determining the type of reaction • Single displacement – 1 element and 1 compound in the reactants and a different element and a different compound in the products. • CuCl2(aq) + Mg(s) MgCl2(aq) + Cu(s) • KCl(aq) + F2(g) KF(aq) + Cl2(g)

  6. Determining the type of reaction • Double displacement - two compounds in the reactants and two different compounds in the products. • FeCl3(aq)+MgSO4(aq)Fe2(SO4)3(s)+MgCl2(aq) • NaCl(aq) + AgNO3(aq) NaNO3(aq) + AgCl(s)

  7. Determining the type of reaction • Neutralization (acid-base) – an acid and a base in the reactants and water as one of the products. • HCl(aq) + NaOH(aq) NaCl(aq) + H2O(l) acid base • Ca(OH)2(aq) + H3PO4(aq)  H2O(l) +Ca3(PO4)2(aq) base acid

  8. Determining the type of reaction • Combustion – a hydrocarbon and oxygen as a reactants and carbon dioxide and water as the only products. • CH4(g) + O2(g) CO2(g) + H2O(g) • C8H18(g) + O2(g) CO2(g) + H2O(g)

  9. More Examples • Determine the type of reaction for each of the following examples: • PbCl2(aq) + KClO3(aq) Pb(ClO3)2(aq) + KCl(aq) • K(s) + F2(g) KF(aq) • LiOH(aq) + H2SO4(aq)  H2O(l) +Li2(SO4)2(aq) • C6H12O6(aq)  CO2(g)+ H2O(g) • C3H8(g) + O2(g) CO2(g) + H2O(g) • MgBr2(aq) + Cl2(g) MgCl2(aq) + Br2(l)
