- Chemical Reaction is the processes in which new substances formed with new properties.
- A Chemical Reaction is a process that occurs when two or more molecules interact to form a new product(s).
- Compounds that interact to produce new compounds are called reactants whereas the newly formed compounds are called products.
- In chemical reaction chemical changes are occur .
- In chemical reaction atom of one element do not change into other element.
- Rearrangement of atom take place in a chemical reaction.
- A reaction can take place between two atoms or ions or molecules, and they form a new bond and no atom is destroyed or created but a new product is formed from reactants.
- The rate of reaction is affected by factors like pressure, temperature, the concentration of reactants.
Components of Chemical Reactions
- Reactants
- Product
(Reactant ) A + B => C + D ( Product)
Reactants
- The substance which take a part in chemical reaction is called Reactants.
- It is placed LHS with a positive sign between them.
- Arrow placed after reactants.
Product
- The substance which find after reactions is called product .
- It is placed RHS with plus sign between them.
- The arrowhead pointed towards the product.
