Chemistry - How to Write Chemical Equations
In chemistry it is imperative that you understand how chemical reactions occur and the right way to describe them. So, take the time to discover ways to create and write a chemical equation.
A reaction is the rearrangement of atoms or ions to form new substances (products). In other words, a reaction always includes the altering of one or more substances (reactants) into one or more newsubstances.
Chemists quantitatively describe reactions with equations based on the empirical evidences recorded within the laboratory. These equations allow chemists to make a number of quantitative predictions about chemical reactions, so you'll want to master this skill.
What is a Chemical Equation?
It's a symbolic representation of a response and divulges three things.
the reactants
the products and
the quantities of each substance concerned
Getting ready for Chemical Equations
The writing of a equation is pretty simple; but you should be familiar with a few things earlier than writing one. You will need to know the next:
tips on how to use the periodic table
methods to write chemical formulas
how to name compounds and
a number of simple symbols
Once you have mastered these elements you're ready to write some equations.
The Symbols
gas (g)
solid (s)
liquid (l)
aqueous (aq)
===> (yields)
7 Steps to Writing Chemical equations
Identify the reactants
Identify the products
Write formulas for the reactants
Write formulas for the products
Write the reactants on the left
Write the products on the right
Place an arrow between them
Example: Write the equation for the response of sodium hydroxide and hydrochloric acid to produce sodium chloride and water.
The reactants could be NaOH and HCl. The products can be NaCl and HOH. Now write the equation with reactants on the left and the products on the right.
NaOH + HCl ===> NaCl + HOH
