what do you mean by combination reation
Answers
A combination reaction (also known as a synthesis reaction[1]) is a reaction where two or more elements or compounds (reactants) combine to form a single compound (product).
There is no specific number of reactants in a combination reaction.
Combination reactions are usually exothermic because when the bond forms between the reactants, heat is released. For example, barium metal and fluorine gas will combine in a highly exothermic reaction to form the salt barium fluoride:
Ba + F2 → BaF2
Another example is magnesium oxide combining with carbon dioxide to produce magnesium carbonate.
MgO + CO2 → MgCO3
Another example is iron combining with sulfur to produce iron(II) sulfide.
Fe + S → FeS
