Question

according to the description below: \calcium carbonate is heated to breakdown.\ identify the type of the reaction. a single displacement b synthesis c combustion reaction d double displacement e decomposition

Explanation:

A decomposition reaction is when a single compound breaks down into two or more simpler substances. Here, calcium carbonate (\(CaCO_3\)) is heated and breaks down (e.g., \(CaCO_3
ightarrow CaO + CO_2\)).

• A single - displacement reaction is \(A + BC

ightarrow AC + B\).

• A synthesis reaction is \(A + B

ightarrow AB\).

• A combustion reaction typically involves a substance reacting with oxygen to produce heat and light (e.g., \(C_xH_y+O_2

ightarrow CO_2 + H_2O\)).

• A double - displacement reaction is \(AB+CD

ightarrow AD + CB\).

Answer:

E. Decomposition
