During my school days I didn't like chemistry that much. But nowadays I am enjoying it. Actually if the basic concept is clear, we don't need to learn by heart the whole equation.

Can you explain it with the help of a few examples. Many students may be benefited by this

Let me give a simple example.
HCl + NaOH =NaCl + H2O
When I was a school student I use to even memorize even simple equation like that. Now with the knowledge that when an acid reacts with base it forms salt and water, we can proceed to write the equation without memorizing. First we write down the reactants involved
HCl + NaOH=
Since HCl is an acid and NaOH is a base, we know that H2O will be one of the products so we can write it down as
HCl + NaOH = H2O
Now what I do is check the atoms of different elemnts in the reactants and take out 2 H and O. that leaves us Cl and Na. Now since, Na is a cation and Cl is an anion, the salt will be NaCl. so now we can write the whole equation as
HCl + NaOH =NaCl + H2O
I don't know if others will find it confusing but I prefer to do it this way instead of memorizing each and every equation.
