Question

Which is combination reaction? Explain it by one chemical equation.​

Answer 1

Answer:

A 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.

Answer 2

Answer:

Combination reaction: The reaction of two or more substances (either elements or compounds) to produce a new substance is called a combination reaction Eg: Magnesium (Mg) on burning in air combines with oxygen to give magnesium oxide. 2Mg(s)+ O2(g) → 2MgO(s)
