SLIDE-2

Single product is formed from the combination of two or

more reactants.

For Example-

SLIDE-3

Combination of elements.

Combination of an element and a compound

2SO2 + O2--------→ 2 SO3

Combination of compounds

Note: Calcium hydroxide is used for white washing walls.

Double Displacement Reaction

SLIDE-11

Double displacement reactions in which formation of

precipitate takes place are called Precipitation reactions.

Note: All double displacement reactions are not precipitation reactions. For eg; Neutralization reactions.

Redox Reaction

SLIDE-12

Also known as Oxidation-reduction Reaction.

Redox Reaction (Electron)

SLIDE-13

NOTE: Fluorine is theReaction transfer of electrons occurs between the two species. strongest oxidizing agent.

.
