Answer:
A + BC → AC + B Single Replacement
AB + CD → AC + BD Double Replacement
A + O₂ → AO Combustion
AB → A + B Decomposition
A + B → AB Synthesis
AC + O₂ → CO₂ + H₂O Combustion
Step-by-step explanation:
- Single replacement is a type of chemical reaction where an element reacts with a compound and takes the place of another element in that compound.
So, A + BC → AC + B is an example for single replacement reaction.
Here, A replaces B in the compound BC.
- Double Replacement is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.
So, AB + CD → AC + BD is an example for double replacement reaction.
Here, A replaces C in the compound CD and B replaces D in the compound CD.
- Combustion reactions always involve molecular oxygen O₂. Anytime anything burns (in the usual sense), it is a combustion reaction. Combustion reactions are almost always exothermic (i.e., they give off heat).
So, A + O₂ → AO and AC + O₂ → CO₂ + H₂O are examples of combustion reactions.
- Decomposition reactions is a type of chemical reaction in which a single compound breaks down into two or more elements or new compounds. These reactions often involve an energy source such as heat, light, or electricity that breaks apart the bonds of compounds.
So, AB → A + B is an example for decomposition reactions.
where Ab is decomposed for A and B.
- Synthesis is a type of reaction in which multiple reactants combine to form a single product. Synthesis reactions release energy in the form of heat and light, so they are exothermic.
So, A + B → AB is an examples for the synthesis reactions.
