Question
Which of the following is a necessary product of a combustion reaction?A.A hydrocarbonB.OxygenC.HeatD.A precipitateSUBMITarrow_backPREVIOUS
Solution
The necessary product of a combustion reaction is C. Heat.
Here's why:
A combustion reaction is a type of chemical reaction where a compound (usually a hydrocarbon) reacts with oxygen to produce heat and light. The heat and light produced is what we commonly refer to as fire.
So, while a hydrocarbon (A) and oxygen (B) are often the reactants (the substances that start a reaction), they are not the products (the substances that are produced by the reaction).
A precipitate (D) is a solid that forms from a solution during a chemical reaction, but it is not a necessary product of a combustion reaction.
Therefore, the necessary product of a combustion reaction is heat (C).
