### What does EQN mean or stand for ?

An EQN is either a mathematical sentence or a chemical one.Yes even Chemistry has equations.To explain what an equation is,simply derive it form the word itself – to equate,or to make equal.All equations have an equal to sign in them (=).There is a left and right side of the equation and both sides are equal.In mathematics,algebra is the sub study that deals with equations and may consist of number and alphabet variables.For example: ax+by=cy.

In chemistry equations are read as HCl+Na2O3=NaCl+H2O3.In chemistry we also have to balance the equations,else they are faulty.
