The s block elements are those elements in which the last electrond enter into the s- orbital of the outermost shell

Vava Lal 6 years, 4 months ago

S block elements are in group one and two they share a similar property .The electron in their most outward electron shell are in the s-orbital.The elements in group one are called the alkali metals. The elements in group two are called the alkaline earth metals.

Real gases show deviation from ideal gas law bcoz molecules interact with each other. At high preasure molecules of gases are very close to each other. At high pressure molecules do not strike the walls of the container with full impact.

The reaction in which reduction and oxidation occurs simultaneously are called redox reaction

Nidhi Sharma 6 years, 4 months ago

The reaction which consist of both oxidation and reduction is known as redox reaction. Hear red means reduction and ox means oxidation, so combination of reduction and oxidation is called redox reaction.

Vikas Moond 6 years, 4 months ago

It is the chemical reaction in which both increase and decrease in oxidation state or number take place.

Shivam Saraswat 6 years, 4 months ago

It is a combination of reduction and oxidation Redox = reduction and oxidation

Yogita Ingle 6 years, 4 months ago

There are two types of Redox reactions

  • Direct Redox reaction
  • Indirect Redox reaction

Direct Redox reaction: In which oxidation and reduction both occur in same beaker. In this electron so produced does not travel to large distance.

For example: A beaker containing Zinc rod dipped in Copper sulphate solution in this the following reaction occur:

Zn    +    CuSO4 -->       ZnSO4 + Cu

Zinc   CopperSulphate  Zinc Sulphate  Copper

In this zinc being more reactive displaces copper from copper sulphate and forms zinc sulphate and copper.

Indirect Redox reactions: In it oxidation and reduction occur in different beakers. The electron so produced has to travel a certain distance that leads to generation of current.

Example: Daniel cell: A cell containing Zn-Cu couple that we are going to study in detail now as given below but before that let us make you familiar with the general term used in redox reaction that is Redox couple.
