the burning of fossil fuels results in which type of chemical reaction? A) decomposition b) single-replacement c) combustion d) synthesis
Answer: The correct answer is Option c.
Explanation: For the given type of reactions:
Decomposition reaction is a type of chemical reaction in which a a larger molecule breaks into two or more smaller molecules.
\(AB\rightarrow A+B\)
Single replacement reaction is a type of chemical reaction in which more reactive metal replaces the less reactive metal in a chemical reaction. The reactivity of the metals is studied with the help of reactivity table.
\(A+BC\rightarrow AC+B\)
Combustion reaction is a type of chemical reaction in which hydrocarbon in the presence of oxygen produces carbon dioxide and water.
\(Hydrocarbon+O_2\rightarrow CO_2+H_2O\)
Synthesis reaction is a type of chemical reaction in which two or more compounds combine to form a single large product.
\(A+B\rightarrow AB\)
All the fossil fuels are organic compounds and hence are considered as hydrocarbons. So, the burning of fossil fuels is a type of combustion reaction.
Hence, the correct answer is option c.
