Question

fe + o₂ → feo
synthesis
decomposition
single displacement
double displacement
combustion

Explanation:

• Synthesis Reaction: A synthesis reaction, also known as a combination reaction, is a type of chemical reaction where two or more reactants combine to form a single product. The general form of a synthesis reaction is \(A + B

ightarrow AB\).

• In the given reaction \(Fe + O_2

ightarrow FeO\), iron (\(Fe\)) and oxygen (\(O_2\)) are combining to form iron (II) oxide (\(FeO\)). This fits the pattern of a synthesis reaction as multiple reactants (\(Fe\) and \(O_2\)) are forming a single product (\(FeO\)).

• Decomposition Reaction: A decomposition reaction is the opposite of a synthesis reaction (\(AB

ightarrow A + B\)), which is not the case here.

• Single - Displacement Reaction: A single - displacement reaction has the form \(A+BC

ightarrow AC + B\), which does not match the given reaction.

• Double - Displacement Reaction: A double - displacement reaction has the form \(AB + CD

ightarrow AD+CB\), which is not applicable here.

• Combustion Reaction: A combustion reaction usually involves a substance reacting with oxygen to produce heat and light, often with more complex products (e.g., for hydrocarbons, \(C_xH_y+O_2

ightarrow CO_2 + H_2O\)). The given reaction is a simple combination, not a typical combustion with the associated heat/light and more complex product scenarios (though technically, oxidation reactions like this can be considered a type of combustion in a very broad sense, but in the context of basic reaction type classification in chemistry courses, it is primarily a synthesis reaction).

Answer:

Synthesis
