Question

how to remember chemical equation in chemistry easily

Answer 1

by adding the chemical euation to our some generel information

Answer 2

Before you remember the chemical equation as whole, better remember the chemical formula itself with the name of chemical eg. Sugar is C6H22O11 or like just saying  common salt  rather remember it as NaCl. This will need some efforts nd patience at first, but as you practice it daily say while just waiting for bus or just sitting in bus or travelling you can  try to remember it. This will make you familiarize the chemical composition of each of crucial and regularly used chemicals. Then while remembering chemical equation just say what are the chemical that are participating in the chemical reaction.
