  • The Ottoman empire disintegrated and European subject nationalities split up demanding their independence.
  • Rivalry was at the peak during this period and the nation states formed various groups and colonies. The best examples of this were during both the World Wars that took place in this century.
  • The concept of nation state was accepted readily in colonies and paved way for them to lead movements asking for independent nation states.

Displacement reaction  Double displacement reaction
In a displacement reaction, a more reactive element replaces a less reactive element from a compound. In a double displacement reaction, two atoms or a group of atoms switch places form new compounds.
In a displacement reaction, one displacement takes place.

 

A + BX → AX + B

In a double displacement reaction, two displacements take place to complete the reaction.

 

AB + CD → AC + BD

Change in colour takes place with no precipitate forms. Precipitate is formed.
Metals react with the salt solution of another metal. Salt solutions of two different metals react with each other.
Examples:

 

2KI + Cl2 → 2KCl + I2 is a displacement reaction.

CuSO4 + Zn → ZnSO4 + Cu is also a displacement reaction.

Examples: 

 

Na2SO4 + BaCl2 → BaSO4 + 2NaCl is a double displacement reaction.

2KBr + BaCl2 → 2KCl + BaBr2 is also a double displacement reaction.

A weak force of attraction between electrically neutral molecules that collide with or pass very close to each other. The van der Waals force is caused by the attraction between electron-rich regions of one molecule and electron-poor regions of another (the attraction between the molecules seen as electric dipoles). The attraction is much weaker than a chemical bond. Van der Waals forces are the intermolecular forces that cause molecules to cohere in liquid and solid states of matter, and are responsible for surface tension and capillary action.

It is a very weak force.....
