Worksheet #2 DECOMPOSITION REACTIONS RULES

IF THE REACTANT IS A SINGLE COMPOUND, THE REACTION IS A DECOMPOSITION REACTION.

GENERAL EQUATION: AB  A + B [ Compound  Element1 + Element2 ]

APPLY THESE RULES TO DECOMPOSTION REACTIONS:

  1. salt  metal + nonmetal

  2. ternary acid  nonmetal oxide (acid anhydride) + water

  3. metal hydroxide  metal oxide (basic anhydride) + water

  4. metal chlorate  metal chloride + oxygen

  5. salt (with polyatomic ion)  nonmetal oxide + metal oxide

  6. metal carbonate  metal oxide + carbon dioxide

  7. metal oxide  metal + oxygen

  8. hydrated salts  anhydrous salt + water

STATES OF MATTER IN DECOMPOSITION REACTIONS:

nonmetal oxides (g) metal oxides (s)

salts (s)

water as a product (g) water as a reactant (l) acids (aq)

individual elements (look at periodic chart for state)

THE DIATOMICS: H2, N2, O2, F2, Cl2, Br2, I2

DIRECTIONS: Determine the products of each reaction. Balance the equation. Indicate the states of matter on all reactants and products. Place the rule number for each to the right of each problem.

  1. ZnCO3  _______________________________

  2. Ba(ClO3) 2 _____________________________

  3. Sb2O5 ________________________________

  4. CaCO3 _______________________________

  5. KClO3 _______________________________

  6. H2CO3 _______________________________

  7. Ba(OH) 2 _____________________________

  8. HgO ________________________________

  9. NaCl ________________________________

  10. H2SO4 _______________________________

11. Ag2O _________________________________ 12. Fe(OH) 2 _______________________________ 13. PBr5 __________________________________ 14. CuSO4 • 5H2O _________________________ 15. Mg(OH) 2 ______________________________ 16. H3PO4 _________________________________ 17. Al(OH)3 ________________________________ 18. Zn(NO3)2 _______________________________ 19. Ca3(PO4)2_______________________________ 20. NaO2 __________________________________
