Types of Chemical Reactions

  1. 1. Types of Chemical Reactions
  2. 2. What combines with what? A B X Y
  3. 3. Types of Chemical Reactions •A synthesis is a type of chemical reaction in which two or more substances combine and form one compound. •You can recognize a synthesis reaction because two or more reactants form only one product. Synthesis
  4. 4. Types of Chemical Reactions •A synthesis is a type of chemical reaction in which two or more substances combine and form one compound. •You can recognize a synthesis reaction because two or more reactants form only one product. Synthesis
  5. 5. Types of Chemical Reactions •In a decomposition reaction, one compound breaks down and forms two or more substances. •You can recognize a decomposition reaction because one reactant forms two or more products. •Decomposition is the reverse of synthesis. Decomposition
  6. 6. Types of Chemical Reactions •In a decomposition reaction, one compound breaks down and forms two or more substances. •You can recognize a decomposition reaction because one reactant forms two or more products. •Decomposition is the reverse of synthesis. Decomposition
  7. 7. Types of Chemical Reactions •In a replacement reaction, an atom or a group of atoms replaces part of a compound. •Two types of replacement reactions can occur: •Single-replacement •Double-replacement Replacement
  8. 8. Types of Chemical Reactions •In a single-replacement reaction, one element replaces another element in a compound. In this type of reaction, an element and a compound react and form a different element and a different compound. Single-Replacement
  9. 9. Types of Chemical Reactions •In a single-replacement reaction, one element replaces another element in a compound. In this type of reaction, an element and a compound react and form a different element and a different compound. Single-Replacement
  10. 10. Types of Chemical Reactions •In a double-replacement reaction, the negative ions in two compounds switch places, forming two new compounds. In this type of reaction, two compounds react and form two new compounds. Double-Replacement
  11. 11. Types of Chemical Reactions •In a double-replacement reaction, the negative ions in two compounds switch places, forming two new compounds. In this type of reaction, two compounds react and form two new compounds. Double-Replacement
  12. 12. Types of Chemical Reactions Combustion •Combustion is a chemical reaction in which a substance combines with oxygen and releases energy. •A combustion reaction usually releases energy as thermal energy and light energy. •Burning is a common combustion reaction. •These reactions always produce carbon dioxide and water.
  13. 13. Types of Chemical Reactions •Combustion is a chemical reaction in which a substance combines with oxygen and releases energy. •A combustion reaction usually releases energy as thermal energy and light energy. •Burning is a common combustion reaction. •These reactions always produce carbon dioxide and water. Combustion

  18. 18. What Type of Chemical Reaction? 4. In a ___________________ reaction, one element replaces another element in a compound. single-replacement double-replacementdecomposition combustion synthesis
  19. 19. What Type of Chemical Reaction? 5. In a ___________________ reaction, two or more elements or compounds combine and form one compound. single-replacement double-replacementdecomposition combustion synthesis
  20. 20. What Type of Chemical Reaction? 6. Energy can be released as light or thermal energy in a ___________________ reaction. single-replacement double-replacementdecomposition combustion synthesis
  21. 21. What Type of Chemical Reaction? 8. 2 C4H10 + 13 O2 ------> 8CO2 + H2O is an example of a ___________________ reaction. single-replacement double-replacementdecomposition combustion synthesis
  22. 22. What Type of Chemical Reaction? 9. HCl + FeS -----> FeCl2 + H2S is an example of a ___________________ reaction. single-replacement double-replacementdecomposition combustion synthesis
