When you are stuck in balancing chemical equations, you may often wonder why you are doing so. Some students do not bother and just balance it because they are told to do so, but some of them try being logical and want to know the actual reason behind balancing it.

It is necessary to balance it because there must be equal number of atoms on both the sides of the equation. Also, it needs to be balanced from both sides, due to the Law of the Conservation of Mass. The law states that there should be an equal quantity of both before and after the experiment, ensuring the quantity and quality remains the same. This law was established by Antoine Laurent in He explored that the matter either cannot be destroyed or created. Moreover, equations need to be balanced properly because unequal equations are not correct equations.

No matter if they have correct elements and quantities, they will not be considered accurate. Also, these unbalanced equations cannot be used in calculating the chemical reactions. In addition to this, chemical equations need to be balanced even because chemicals will not react until you have added the correct mole rations.

Additionally, balanced equation is necessary in determining how much reactant you would need to have, for making the specific product. This simply means that the correct products will not be formed unless you add the right amount of reactants. Some students really find the balancing equations difficult in balancing equations worksheet.

It is hard and may require struggle but all you need to do is practice, have patience and need to have good memory. At first, you may face difficulties but you need to keep on working hard and surely you will succeed. We will be explaining the tips below in our further section, but here are brief ones.

You need to learn reactions and write formulae of reactants. Understand the concept and balance the equation. Once you understand the concept, you will be surprised at how easy balancing will become for you. It may seem hard to believe right now, but keep working on these equation, and they will suddenly just click. Before we help you in understanding the tips and tricks of balancing equations, you first need to know the types of chemical equations.

Basically, there are five types of chemical equations and their reactions. Check them out below. This is the most common type of chemical equation. In this chemical equation, a new product is formed by combining two to three combinations of reactants. This is a chemical equation where two atoms of hydrogen are combined to form a product, water.

This is why this reaction is called as synthesis reaction. Additionally, this is also an unequal equation because there are two atoms present for the oxygen on the reactant side while there are is only one atom on the oxygen side for product.

But the equation is only valid when the number of atoms and moles are equal on both sides. You can balance the equation using the combustion method which will be explained later. Decomposition chemical reaction is the reaction where only one compound decomposes and results in two or more than two products. In this equation, lead nitrate is being decomposed, which breaks down to form nitrogen dioxide, oxygen, and lead oxide.

This is an example of a decomposition reaction. Another very common chemical reaction is of two types, i. In single displacement reaction, any one chemical partner exchanges from reactants to products while two sets of chemical partners exchanges from reactants to products. In this example, zinc will replace hydrogen from sulfuric acid to form zinc sulfate. As you see, only one cation is being swapped here, that means that it is a single displacement reaction.

In this equation, chloride ion leaves Barium and attaches to sodium. This is the chemical reaction where an oxygen compound and carbon compound combine together to become H 2 O and CO 2. It is the reaction where mostly an organic compound like oxygen burns yielding to water, carbon dioxide, or some other product. The combination of any substance with oxygen results in combustion.

This is the simple chemical reaction where acid and base are combined together to provide water and salt. This reaction is also called as neutralization reaction and most commonly called as acid-base reaction. These are really important type of reactions that occur in biological systems.

When students often get frustrated, they opt for balancing chemical equations worksheet answers to resolve the problem. If you also find difficulty in balancing the chemical equations, follow the steps below. The first step to balance the equation is to write down the chemical formula of reactants that are listed on the left side of the chemical equation. After this, you can list down the products on the right hand side of the chemical equation.

Equations you write a chemical equation, a necessary step is to balance the number of atoms on both sides of the equation. For example, chemistry the homework reaction one molecule of hydrogen H 2 and an atomic form of oxygen O are sufficient to produce a molecule of help H balancing O. The mass of substances produced in a chemical reaction is equal to the mass of reacting substances. An equation has the same number of elements on both sides.
