Answer:
Explanation:
1. Â The reaction has at least two reactants and one product
Synthesis
Synthesis is a sort of combination reaction in which a single product is formed from  two or more reactants:
        A + B → C
2. Â The reaction has one reactant and at least two products
Decomposition
In decomposition reaction, a compound breaks down into individual elements or compounds.
      A → B + C
3. Â Oxygen is one of the reactants and a large amount of energy is released
Combustion
In combustion reaction, oxygen combines with a fuel source to produce energy.
4. Â One or more atoms replaces a part of a compound
Replacement
In this type of reaction, one substance replaces another we say it is a single replacement reaction. Some other types involves the actual exchange of partners.
5. The products are always salt and water
Neutralization
Neutralization reaction is a reaction in which acids reacts with bases to produce salts and water.
