The ubderstandable notes - Chemical reaction and equations, Class 10, Part 2
BALANCED CHEMICAL EQUATION In order to validate the law of conservation of mass, chemical equations are balanced. Balancing a chemical equation means that the number of atoms of each element should be the same on both sides (reactants as well as products). This can be done by several methods, but the simplest is the hit-and-trial method. (Ab dekho ki balancing krni kyu padti hai to IX class mai humne padha tha agar nahi padha to ab padh lo ek law tha law of conservation of maas, jiske andar ye kehte the ki total maas before the reaction and after the reaction will be same ab dekhte hai ek simple se reaction par Ab agar hum is reaction ko dekhe to reactants side par oxygen aur hydrogen ke 2 atoms hai aur product side par oxygen ka sirf ek atom hai. Matlab ki maas of reactant is 34u aur maas of product is 18u to ab yaha law of conservation of energy kaha gaya, isliye hume balancing krni padti hai ab balancing mai basically ye hoga ki har element ka single atom bhi both ...
