Introduction to Chemical Equations In a word equation, write the names of the reactants to the left of the arrow, separated by plus signs. Write the names of the products to the right of the arrow, also separated by plus signs. –Notice that no plus sign is needed on the product side...
Chemical Equations If you were to describe a chemical reaction in a sentence, it would be quite long. To express it in a shorter form, we can write it as a word-equation. For example, the reaction between magnesium and oxygen to give magnesium oxide can be represented as follows – Magne...
Before we define chemical equilibrium, let's first review the basics of chemical reactions and equations. A chemical reaction is a process in which one or more substances are changed into one or more new substances. It may not be obvious, but chemical reactions occur in many places. For exam...

2O +2H = H2O2 ReactantsProducts O22✔️ H22✔️ Since there is an equal number of each element in the reactants and products of 2O + 2H = H2O2, the equation is balanced. Balance O + H = H2O2 Using Inspection Balance O + H = H2O2 by inspection or trial and error with ...
For the example, note that there is an extra O2 going in, so there is an extra coming out. Just be sure that the Law of Conservation is observed at all times. Anything that goes in has to come out. TL;DR (Too Long; Didn't Read) Generally, chemicals in these types of equations ...
Key Takeaways: Examples of Balanced Equations In chemistry, it's important to be able to recognize when equations are balanced, when they are not balanced, and how to balance them. A balanced equation contains the same number of each type of atoms on both the left and right sides of the...
