Answer:
Double replacement reaction
Step-by-step explanation:
A decomposition reaction occurs when a specific chemical is "decomposed" or broken down into simpler elements or compounds. Seeing the chemical equation, this particular reaction clearly does not demonstrate that. A double replacement reaction, on the other hand, occurs when two chemicals switch locations in the chemical reaction. In this particular reaction, hydrogen (H), and bromine (Br) swap locations. Seeing so, this chemical equation is a double replacement reaction.
