Answer 1

$\huge \mathfrak{Answer }$

Chemical reactions:-

1. Combination reaction

A reaction in which two or more substances combine to form a single compound.

For example,

2H2 + O2 => 2H20

2. Decomposition reaction

A reaction in which a compound splits into two or more substances in the presence of light, heat and electricity.

For example,

2H20 => 2H2 + O2 (electricity )

3. Displacement reaction

A reaction in which less reactive substance is removed by highly reactive substance.

For example,

Fe + CuSo4 => FeSo4 + Cu

4. Double Displacement reaction

A reaction in which substances are formed by mutual exchange of ions.

For example,

Na2So4 + BaCl2 => 2NaCl + Baso4

6. Redox reaction

A reaction which is either followed by oxidation or reduction of substances.
