Fundamental Law of the Conservation of Mass
The law of the conservation of mass states that the total weight of a reaction cannot change because matter cannot be destroyed or created. During a chemical reaction, the mass of the reactants and products must be the same. The total number of atoms stays equal. Elements cannot magically appear or disappear in a reaction, so you have to account for all of them.
Steps involved in balancing a Chemical Equation:
Step 1: Write the correct skeleton equation.
Step 2: Start with the compound that has the maximum atoms or maximum kinds of atoms and the atoms present in it are balanced first.
Step 3: Balance elements that appear only once on each side of the arrow first. Then balance elements that appear more than once on a side.
Step 4: Elementary substances are balanced last of all.
Step 5: If required the whole equation is multiplied by some suitable number in order to make all the coefficients whole numbers.
