What kind of reaction is 2H2O2 2H2O + O2?A.SynthesisB.Single-replacementC.DecompositionD.Double-replacementSUBMITarrow_backPREVIOUS

Breakdown the Problem

1. Identify the reactants and products in the given chemical equation:
   $2H_2O_2 \rightarrow 2H_2O + O_2$
2. Determine the characteristics of the reaction.

Relevant Concepts

1. Types of Reactions:
   • Synthesis: Two or more substances combine to form a new compound.
   • Single-replacement: One element replaces another in a compound.
   • Decomposition: A single compound breaks down into two or more elements or new compounds.
   • Double-replacement: The ions of two compounds exchange places in an aqueous solution to form two new compounds.

Analysis and Detail

1. In the reaction, we begin with hydrogen peroxide ($H_2O_2$), which decomposes into water ($H_2O$) and oxygen gas ($O_2$).
2. This indicates that one compound is breaking down into simpler substances (water and oxygen), which fits the definition of a decomposition reaction.

Verify and Summarize

1. Since the reaction involves one substance (hydrogen peroxide) breaking down into multiple products (water and oxygen), it confirms that the type of reaction is indeed a decomposition.

Final Answer

C. Decomposition
