Balancing Chemical Equations for beginners
Description
You will learn about "Balancing Chemical Equations" in this video. The law of conservation of mass states that mass can neither be created nor destroyed in a chemical reaction. This means that the number of atoms in each element should remain the same before and after a reaction.
Let us understand this with the help of an example. Hydrogen combines with nitrogen to give ammonia. Here, 2 is the subscript, which tells us the number of hydrogen and nitrogen atoms. Now, we need to balance the number of atoms on both the sides. There are 2 hydrogen atoms in the reactant and 3 in the product. Also, there are 2 nitrogen atoms in the reactant and only 1 in the product. We need to multiply hydrogen atoms by 3 and ammonia by 2. Now, there are 3 * 2, i.e. 6 hydrogen atoms in the reactant and 2 * 3, i.e. 6 hydrogen atoms in the product. Similarly, there are 2 nitrogen atoms in the reactant and 2 * 1, i.e. 2 nitrogen atoms in the product. Hence, this chemical equation is now perfectly balanced.
