Answer

Explanations: A single replacement reaction is defined as a reaction where one element replaces another element in a compound. In the given reaction, iron (Fe) replaces hydrogen (H) in water ($H_2O$), forming iron oxide ($Fe_3O_4$) and hydrogen gas ($H_2$), which matches the pattern of a single replacement reaction. Double replacement involves swapping of ions between two compounds, combustion requires oxygen as a reactant and produces oxides, and decomposition breaks a single compound into simpler substances, none of which fit this reaction.

Answer:

Single Replacement
