Question

There are five types of reactions first combination reaction decomposition reaction displacement reaction double displacement reaction oxidation and reduction reaction
And the question was each reaction and each experiment and describe it.

Answer 1

Combination Reaction : This is a type of Reaction in which two or more substances combine to form a single substance
EX : H2 + O2 -} H2O
Decomposition reaction : This is a type of che.icla reaction in which a single substance decomposes into two or many substances .
EX : CaCO3 -} CaO + CO2
Under displacement reaction , A more reactive metal or non metal displaces less reactive metal or non metal .
EX : CuSO4 + Mg -} MgSO4 + Cu
Under double displacement reaction , Atom or group of atom gets displaces by another atom or group atom .
Redox Involves reduction
and Oxidation

Answer 2

Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.Nov 4, 2020
