Chemical Reaction And Equations

On completion of this lesson, students should be able to:

  • Explain the different types of chemical reaction.
  • Write chemical equations and balance them.
  • Explain the advantages and limitations of balanced chemical equation.
  • Explain the conditions required for chemical reactions.
  • Explain about mole concept.


Chemical Reaction

The process of breaking old binding force and the formation of new binding force in product is called chemical reaction. This note is about an introduction on chemical reaction.

Molecular Weight and Concept of Mole

The sum total of the number of protons and neutrons present in the nucleus of an atom is called atomic weight. This note is a brief introduction on Mole Concept and its calculations.

Types of Chemical Reaction

Chemical reaction is a process of converting one or more substances into other new substances. The main four types of reactions are combination reaction, decomposition reaction, displacement reaction and acid- base reaction. This note provides information about the types of chemical reaction and catalyst.

Conditions Required in Chemical Reaction

The chemical equation which is written in terms of symbols by writing their molecular formula is called formula equation. This note has different types of equations.
