Types of Chemical Reactions

PART ONE: Write the word equations below as chemical equations & identify the type of reaction.

  1. Zinc reacts with lead (II) nitrate to yield zinc nitrate and lead

Zn + Pb → Zn(NO3)2 + Pb Synthesis

  1. Aluminum bromide reacts with chlorine to yield aluminum chloride and bromine

AlBr3 + Cl - > AlCl3 + Br Single replacement

PART TWO: Choose the correct symbol for the type of reaction.  Place that answer in the blank at the beginning of each equation.

S = synthesis SR = single replacement

D = decomposition DR = double replacement

C = combustion

  1. SR  Na (s) + H2O (l) →  NaOH (aq) + H2 (g)

  2. S  CO (g) + O2 (g) →  CO2 (g)

  3. DR  FeS (s) + HCl (aq) →  FeCl2 (aq) + H2S (g)

  4. D  NaNO3 (s) →  NaNO2 (s) + O2 (g)

  5. SR  CH4 (g) + O2 (g) →  CO2 (g) + H2O (g)

  6. SR  Fe (s) + CuNO3 (aq) →  Cu (s) + Fe(NO3)2 (aq)

  7. SR  KI (aq) + Cl2 (g) →  KCl (aq) +I2 (aq)

  8. S  Al (s) + S (s) →  Al2S3 (s)

  9.  D  KClO3 (s) →  KCl (s) + O2 (g)

  10. C  C4H10 (g) + O2 (g) →  CO2 (g) + H2O
