A brief overview of the chemical equation balancer

Symbolic representation of chemical equations is to balance the equation in the form of symbols and chemical reactions.

In the left-hand column, reactants are written, and in the right-hand column, products are written. Equation balancer involves the stoichiometry coefficient. It can allow us to use it without any payment method. The equation balancer online tool helps to make our equation simple and easy to convert. It also provides several useful options that will help you in many fields. It is specially designed to fulfill your requirements in chemistry subjects.

For example

Na (plus)+ Cl (equal)= NaCl

What is the Stoichiometry Coefficient?

The numbers that are written at the front of molecular mass, ions, and chemical equation to balance the equation of elements on both the reactants and products are called stoichiometry coefficients.

Define Reactants.

In the chemical equations, when we balance the equation. The chemical components that are written on the left side of the equation, are known/called reactants.

Reactants are formed products. Reactants play an important role in chemistry. With the help of reactants, the equation is placed in the periodic table.

For example

Na (plus)+ Cl (equal)= NaCl

In this example, there are Na and Cl, they are reactants. With the help of the given example, you can easily understand the concept of reactants.

What are products?

In chemical equations, when we balance the equation. The chemical components that are written on the right side of the equation, are known/called products.

Products are formed with the help of reactants. Products plays an important role in chemistry.  With the help of reactants, the equation is placed in the periodic table.

For example:

Na (plus)+ Cl (equal)= NaCl

In this example, there is a NaCl. This is a product.  This example helps you to understand the concept of products.

Methods of balancing the equation:

In order to balance chemical equations, the first step is to obtain the complete unbalanced equation. An example of this method is the combustion reaction between propane and oxygen.

Step 1

  • If not provided already, the chemical formulae of the reactants and products must be used to obtain the unbalanced equation.
  • Propane has the chemical formula C3H8. Water (H2O) and carbon dioxide (CO2) are produced when it burns with oxygen (O2).
  • An unbalanced chemical equation can be written as CH8 (plus)+ O2 → CO2 (plus)+ H2O.

Step 2

The total number of atoms on the reactant side and the product side must be compared. For example, the number of atoms on each side can be tabulated as follows.

Chemical Equation:

                                 C3H8 + O2 CO2 + H2O

Reactant SideProduct Side
3 Carbon atoms comes from C3H81 Carbon atom comes from CO2
8 Hydrogen atoms comes from C3H82 Hydrogen atoms comes from H2O
2 Oxygen atoms comes from O22 comes from CO2, 3 Oxygen atoms and 1 from H2O

Step 3

  • Stoichiometric coefficients are now added to molecules containing an element that has a different number of atoms on the reactant and product sides.
  • There must be a balance between the number of atoms on each side of the coefficient.
  • In general, hydrogen and oxygen atoms receive the last stoichiometric coefficients.
  • In order to update the atom counts of the reactants and products, we must update the atom counts of the reactants and products.
  • To calculate the number of atoms of an element present in one molecule of a species, multiply the stoichiometric coefficient with the number of atoms of that element present in one molecule.
  • When the CO2 molecule has the coefficient 3, the total number of oxygen atoms in CO2 becomes 6. As shown in the following table, carbon is the first element to be assigned a coefficient.

Chemical Equation: C3H8 (plus)+ O2 3CO2 (plus)+ H2O

Reactant SideProduct Side
3 Carbon atoms comes from C3H83 Carbon atoms comes from CO2
8 Hydrogen atoms comes from C3H82 Hydrogen atoms  comes from H2O
2 Oxygen atoms comes from O26 comes from CO2, 7 Oxygen atoms and 1 from H2O

Step 4

Repeat step 3 until all atoms of the reacting elements are equal on the reactant and product sides. The next step in this example is to balance hydrogen. In order to transform the chemical equation, follow these steps.

Chemical equation: C3H8 (plus)+ O2 3CO2 (plus)+ 4H2

Reactant SideProduct Side
3 Carbon atoms comes from C3H83 Carbon atoms comes from CO2
8 Hydrogen atoms comes from C3H88 Hydrogen atoms comes  from H2O
2 Oxygen atoms comes from O26 Oxygen atoms come from CO2 and 4 from H2O

Following the balance of hydrogen atoms, oxygen is the next element to be balanced. On the product side, there are 10 oxygen atoms, so the reactant side must also contain 10 oxygen atoms.

Each O2 molecule contains two oxygen atoms. Thus, the O2 molecule must have a stoichiometric coefficient of 5. As shown in the table below, the chemical equation has been updated.

Chemical Equation: C3H8 (plus)+ 5O2 3CO2 (plus)+ 4H2O

Reactant SideProduct Side
3 Carbon atoms comes from C3H83 Carbon atoms comes from CO2
8 Hydrogen atoms comes from C3H88 Hydrogen atoms comes from H2O
10 Oxygen atoms comes from O26 comes from CO2, 10 Oxygen atomsand 4 from H2O

Step 5

  • In order to compare the total number of atoms of each element on the reactant and product sides once again, all the individual elements must be balanced.
  • Chemical equations are said to be balanced if there are no inequalities.
  • Every element in this example now has an equal number of atoms in the reactant and the product.
  • Thus, C3H8 (plus)+ 5O2 (multiply)x 3CO2 (multiply)x 4H2O is the chemical equation that balances.
