Chemical Reaction

<aside> 💡 One or more substances react to form new substances with new chemical identities and properties.

How to determine it??!!

• Change in STATE
• Change in COLOR
• Change in TEMPERATURE
• Evolution of GAS

Chemical Equation

<aside> 💡 A chemical equation is a symbolic representation of a chemical reaction.

Skeletal Chemical Equation

<aside> 💡 A chemical equation in which the no. of atoms of each element on the reactants side is not equal to that of the products side.

</aside>

Balanced Chemical Equation

<aside> 💡 Chemical equation in which the no. of atoms of each element on the reactants side is equal to that of the products side.

• It is done to follow the law of conservation of mass.
• The method used for balancing is called the Hit and Trial Method.

<aside> ‼️ SUMMARY: A chemical reaction is a process where substances react to form new substances with different properties. It can be determined by changes in state, colour, temperature, or the evolution of gas. A chemical equation is a symbolic representation of a chemical reaction. A skeletal chemical equation is one where the number of atoms of each element on the reactants side is not equal to that of the products side. A balanced chemical equation is one where the number of atoms of each element on the reactant side is equal to that of the product side, following the law of conservation of mass. The Hit and Trial Method is used for balancing.
