The right response is combustion reaction and synthesis reaction.
A hydrocarbon reacting chemically with oxygen to produce carbon dioxide and water is known as a combustion reaction.
[tex]hydrocarbon + O_{2}[/tex] → [tex]CO_{2} + H_{2}O[/tex]
The term "synthesis reaction" refers to the chemical process wherein elements combine to generate a single product.
[tex]A + B[/tex] → [tex]AB[/tex]
Because hydrogen and chlorine combine to form the molecule of hydrochloric acid in their elemental states, this process is regarded as a synthesis reaction.
For A : [tex]H_{2} + Cl_{2}[/tex] → [tex]2HCl[/tex]
Because hydrogen gas and chlorine gas are mixed in their elemental states to create the hydrochloric acid molecule, this process is regarded as a synthesis reaction.
For B: [tex]CH_{4} + 2O_{2}[/tex] → [tex]CO_{2} + 2H_{2}O[/tex]
Because methane and oxygen combine to create carbon dioxide and water molecules, this reaction is regarded as a combustion reaction.
