Types of Chemical Reactions
By: Ellie Burch
Synthesis:
- Definition: a type of reaction in which multiple reactants combine to form a single product
- Equation: A+B --> AB
- Examples: Fe(2) + O(2) --> FeO(2) & 2Li + Cl(2) --> 2LiCl
Decomposition:
- Definition: analysis or breakdown is the separation of a chemical compound into elements or simpler compounds
- Equation: AB --> A+B
- Examples: 2HgO --> 2Hg + O(2) & BC --> B + C
Single Replacement:
- Definition: is a type of oxidation-reduction chemical reaction when an element or ion moves out of one compound and into another - that is, one element is replaced by another in a compound.
- Equation: A + BC --> B + AC
- Examples: A + BX --> B + AX and D + AB --> A + DB
Double Replacement:
- Definition: a type of chemical reaction where two compounds react, and the positive ions and the negative ions of the two reactants switch places, forming two new compounds or products.
- Equation: AB + CD --> AD + CB
- Examples: AgN(3) + NaCl + NaNO(3) & MgO+ CaS --> MgS + CaO
Combustion:
- Definition: reaction in which one of the reactants is oxygen. ▪ The other reactant is usually a hydrocarbon.
- Equation: C(6)H(14) + O(2) --> CO(2) + H(2)O
- Examples: Fe(2)O(3) + C --> Fe + CO(2) & CH(4) + 2O(2) --> CO(2) + 2H(2)O
