Final answer:
The equation represents a decomposition reaction where one compound splits apart into two or more substances.
Step-by-step explanation:
Decomposition reactions
The decomposition reactions are the reverse of the combination reaction, i.e., one compound splits apart into two or more substances, usually by heating, e.g.:
H₂CO3 →H,O+CO,
Since the given equation does not fit into the definition of a synthesis, combustion, or substitution reaction, it is classified as a decomposition reaction.
Answer Summary:
The equation represents a decomposition reaction where one compound splits apart into two or more substances.
