Wikipedia
Combination reaction
A direct combination reaction (also known as a synthesis reaction) is a reaction where two or more elements or compounds (reactants) combine to form a single compound (product). Such reactions are represented by equations of the following form: X + Y → XY (A+B → AB). The combination of two or more elements to form one compound is called a combination reaction. In other words, when two or more elements or compounds react so as to form one single compound, then the chemical reaction that takes place is called a combination reaction. | a)- Between elements | C + O2 → CO2 | Carbon completely burnt in oxygen yields carbon dioxide |- | b) Between compounds | CaO + H2O → Ca(OH)2 | Calcium oxide (lime) combined with water gives calcium hydroxide (slaked lime) |- | c) Between elements and compounds | 2CO + O2 → 2CO2 | Oxygen combines with carbon monoxide,And carbon dioxide is formed. |} There is no specific number of reactants in a combination reaction.

Combination reaction
A combination reaction is a reaction where two reactants are combined into one product.Those reaction in which two or more elements or compounds combine together to form a single compound are called combination reaction. They may be represented by X + Y → XY Combination reactions are usually exothermic. For example barium metal and fluorine gas will combine in a highly exothermic reaction to form the salt barium fluoride: Another example is magnesium oxide combining with carbon dioxide to produce magnesium carbonate. Another example is Iron combining with Sulphur to produce Iron Sulfide. Often, reactions can fall into more than one category. For example the combustion of magnesium metal is also a combination reaction as it releases magnesium oxide and energy. This reaction is usually exothermic because when the bond forms between the reactants, heat is released. A combination reaction can be of three types: When a combination reaction occurs between a metal and a nonmetal the product is an ionic solid. An example could be lithium reacting with sulfur to give lithium sulfide. When magnesium burns in air, the atoms of the metal combine with the gas oxygen to produce magnesium oxide. This specific combination reaction produces the bright flame generated by flares. There is no specific number of products that can be formed in combination reaction.
