Why combination reaction is opposite to displacement reaction?
Verified Answer
Why combination reaction is opposite to displacement reaction?
Combination reactions and displacement reactions are opposite types of chemical reactions because they involve the combination or separation of different substances.
A combination reaction is a chemical reaction in which two or more substances combine to form a new compound. In a combination reaction, atoms from different elements come together to form a single compound. For example, the combination of hydrogen and oxygen to form water is a combination reaction:
2H2 + O2 -> 2H2O
In a displacement reaction, a more reactive element or compound replaces a less reactive element or compound in a compound. This usually involves the transfer of an atom or group of atoms from one compound to another. For example, the reaction of zinc with hydrochloric acid is a displacement reaction:
Zn + 2HCl -> ZnCl2 + H2
In this reaction, the zinc atom in the zinc metal is displaced by the hydrogen ions in the hydrochloric acid, resulting in the formation of zinc chloride and hydrogen gas.
In summary, combination reactions involve the combination of two or more substances to form a new compound, while displacement reactions involve the replacement of one element or compound with another.
