[tex]MgO(s) + H_2O(l)[/tex]→ [tex]Mg(OH)_2[/tex](aq) is a combination reaction because in this reaction combination of [tex]MgO[/tex] and [tex]H_2O[/tex] is taking place.
What is a combination reaction?
A combination reaction is a reaction where two or more elements or compounds combine to form one compound. Such reactions are represented by equations in the following form: X + Y → XY.
The combination of two or more elements to form a single compound is called a combination reaction.
For example, lithium reacts with sulfur to give lithium sulfide. When magnesium burns in the air and the atoms of the metal combine with the gas oxygen to give magnesium oxide.
Hence, [tex]MgO(s) + H_2O(l)[/tex]→ [tex]Mg(OH)_2[/tex](aq) is a combination reaction because in this reaction combination of [tex]MgO[/tex] and [tex]H_2O[/tex] is taking place.
