Important Topics for NCERT Exemplar Class 10 Science Solutions Chapter 1: Chemical Reactions and Equations

 

  • Chemical change 

 

When one or more new substances are formed, the change which takes place is known as the chemical change. When a chemical change takes place, the formation of new substances takes place, changes in energy take place, also the change which takes place is permanent. An example of chemical change is when iron rusts, food is cooking, etc. Chemical changes can also be known as chemical reactions.

 

  • Types of reactions

 

  • Exothermic Reactions
  • Endothermic Reactions
  • Synthesis Reactions
  • Decomposition Reactions
  • Double Displacement Reactions 

 

  • Chemical equations 

 

When a chemical change is represented in the form of terms and symbols of the product formed and reactant used in the reaction, it is known as the chemical equation of the reaction.

 

  • Steps for Writing Chemical Equation

 

  • Firstly write the Raw form of Equation
  • Balance the chemical equation

 

  • Chemical Formulae

 

The symbolic representation of the actual number of atoms present in a molecule of the substance is known as the chemical formulae of the substance.

 

  • Double displacement reaction

 

When 2 compounds react together to form 2 different compounds by their mutual exchange of the ions, it is known as a double displacement reaction.            

 

  • Oxidation and reduction

 

  • The process in which electrons are lost is known as oxidation. The substances which bring out the process of oxidation are known as Oxidizing Agents.
  • The process in which electrons are gained is known as reduction. The substances which bring out the process of reduction are known as Reducing Agents.
