Chemical Reactions and Equations (ৰাসায়নিক বিক্ৰিয়া আৰু সমীকৰণ)

Solved
Q1. What is a balanced chemical equation? Why should chemical equations be balanced?

Answer: A reaction in which the number of atoms of each element is equal on both the reactant and product sides is called a balanced chemical equation. According to the Law of Conservation of Mass, mass can neither be created nor destroyed in a chemical reaction. Therefore, the total mass of elements in products must equal reactants.

অসমীয়া প্ৰশ্নোত্তৰ (Assamese Medium Note):

ৰাসায়নিক সমীকৰণ সমতুল কৰা প্ৰয়োজন কিয়নো ভৰৰ সংৰক্ষণ সূত্ৰ অনুসৰি কোনো ৰাসায়নিক বিক্ৰিয়াত ভৰৰ সৃষ্টি বা বিনাশ হ'ব নোৱাৰে।
