Answer
Combination reaction
Reason — A combination reaction occurs when two or more substances combine to form a single product. When a metal burns in air , it reacts with oxygen to form a metal oxide.
A displacement reaction occurs when one element replaces another in a compound. A decomposition reaction occurs when a compound breaks down into simpler substances. A double displacement reaction occurs when there is an exchange of ions between two compounds.
