An easy way to understand this is to picture a house made of blocks. This means that chemical reactions do not change the actual building blocks of matter rather, they just change the arrangement of the blocks. So, if we start with ten atoms of oxygen before a reaction, we need to end up with ten atoms of oxygen after a reaction. This stems from the universal law of the conservation of mass, which states that matter can neither be created nor destroyed. So, Oxygen atoms are not balanced at the products side.The ultimate goal for balancing chemical equations is to make both sides of the reaction, the reactants and the products, equal in the number of atoms per element. A balanced equation is nothing but the equation where number of atoms in each element in reactants and products are same. What does meant by balancing chemical equations?Ĭhemical Equation is defined as the symbolic representation of chemical reaction.
