Answer:
Decomposition reaction
Explanation:
A chemical reaction that has the general formula of AB → A+B is best classified as a Decomposition reaction.
General equation;
AB → A + B
It is the reaction in which one reactant is break down into two or more product.
For example:
2NaCl → 2Na + Cl₂
Sodium chloride is ionic compound. It is made of two constituents sodium and chloride. When it decompose it gives its constituents element sodium and and chlorine.
Another example:
2Al₂O₃ → 4Al + 3O₂
Aluminium oxide decompose and gives its constituent elements aluminium and oxygen.
