Chemical Equation Calculator: Learning how to balance a chemical equation equation is necessary as it is mandatory while writing the chemical equations with accurate information. You may feel the entire process is a bit confusing and time consuming at times. So, to help you in such situations we have come up with a handy tool that does all your calculations instantaneously. Make your calculations easy, accurate and get the detailed process to balance the chemical equation.

Chemical equation is defined as the symbolic representation of the chemical reaction. Here, we are giving the detailed step by step procedure that to be followed while balancing any chemical equation.

• Let us assume any chemical equation
• At first count the number of each and every atoms on right hand side and left hand side of the equation
• Add numbers to the reactants and products to make the number of items on both sides are equal.
• Cancel the common terms in denominator, numerator

Examples

Question1: Balance the following chemical equation C2H6+O2->CO2+H2O?

Solution:

Given chemical equation is

C2H6+O2->CO2+H2O

In the given equation we have 2 Carbon items, 6 Hydrogen and 2 Oxygen items at one side.

The other side of the equation has one Carbon, 2 Hydrogen and 3 Oxygen

By seeing the equation, we have to balance carbon and oxygen numbers

To balance the Carbon items just add 2 in front of CO2 but oxygen items are not balanced

So add 4 in front of CO2 and 6 in front of Water (H2O)

The equation becomes

2C2H6+7O2->4CO2+6H2O

Question2: Balance the equation H2+O2->H2O?

Solution:

Given Chemical equation is

H2+O2->H2O

Two Hydrogen and 2 Oxygen items on one side and two Hydrogen and one Oxygen on the other side of the equation.

So, we need to balance the Oxygen items only.

2H2+O2->2H2O

Whether it is an mathematical expression or Chemical Equation or Chemical Reaction, you can calculate with the online free tools provided at Chemistrycalc.Com.

1. What are the different types of chemical reaction?

The different primary types of chemical reactions are as listed here

Combination reaction

Displacement reaction

Decomposition reaction

Double displacement reaction

2. What are the steps involved in writing a chemical equation?

The steps involved in representing a chemical equation are mentioned here:

The reactants are written on the left hand side and products are written on the right hand side of the equation

An arrow pointing towards the products is inserted between the reactants and products.

Arithmetical plus sign is inserted between the products, reactants.

3. What are the parts of a chemical equation?

Each and every chemical equation should have these parts. They are Reactants, Products, Coefficients, Subscripts, Arrow, and Law of Conservation of Mass.

4. What are the examples of chemical equation?

In general, chemical changes involve chemical equation and the creation of new products. Chemical changes are irreversible. The common chemical changes observed in human life are Burning Wood, Boiling Egg, Baking a Cake, Rotting Bananas, Using a chemical battery, and others.

5. What are the main differences between chemical change and physical change?

Chemical change is a permanent change where physical is a temporary change. Physical change affects only physical properties i.e shape, size, colour but chemical change affects both physical and chemical properties. The best examples of chemical changes are boiling egg, burning of coal, for physical changes are melting wax, boiling of water and freezing of water.

Here we are giving the 5 simple steps to balance any type of chemical equation. Follow these guidelines and balance your equation easily and quickly.

• Count the number of atoms on each side of the equation
• Check the coefficients of atoms and add any number n as coefficient for the required atoms to balance the equation.
• You are just allowed to place coefficient in front of the reactant or product, but not allowed to change subscripts of the elements.
• After adding the coefficients once check the number of atoms on left side are equal to number of atoms on right side.
• Change the coefficients for the required atoms to get the equation balanced.
• When you are dealing with poly atomic ions, treat every poly atomic ion as one item.
• Add coefficients to those items to get the balanced equation.
• Sometimes, count all the atoms in the chemical equation even if it has poly atomic ions and add coefficients to it to get the balanced equation.

Example

Question: Balance this equation: CaCl2 + AgNO3 → Ca(NO3)2 + AgCl?

Solution:

Given unbalanced equation is

CaCl2 + AgNO3 → Ca(NO3)2 + AgCl

Write down the number of atoms in each element

Left hand side has Ca=1, Cl= 2, Ag= 1, N= 1, O= 3

Right hand side has Ca= 1, Cl= 1, Ag= 1, N= 2, O= 6

Nitrogen, Chlorine and Oxygen atoms are not balanced.

Add 2 infromt of AgNO3 and AgCl.

Left hand side has Ca=1, Cl= 2, Ag= 1*2 = 2, N= 1*2 = 2, O= 3*2 = 6

Right hand side has Ca= 1, Cl= 1*2 = 2, Ag= 1*2 = 2, N= 2, O= 6

Finally, the equation is balanced.

CaCl2 +2 AgNO3 → Ca(NO3)2 + 2AgCl

1. What are the rules for balancing the chemical equation?

• Apply the Law of Conservation of Mass to get the same number of atoms on each side of the chemical equation.
• Start by balancing an element that is available in only one reactant and product.
• Once balancing of the one element is completed, proceed further until all elements are balanced in the equation.
• Balance the chemical equation by putting coefficients in front of them. You are not supposed to add subscripts, because it will change the reaction.

2. Do you add or multiply when balancing equations?

The important point to remember while balancing equation is never change its subscripts, add coefficients to them. Always multiply the coefficients of the atoms by its subscript to identify the number of elements in the reaction.

3. How to balance long chemical equation using algebraic method?

• At first, add variables a,b,c,d, so on as coefficients to all the reactants and products.
• Take a note of number of elements on the right hand side and left hand side.
• Equate any one element number of molecules on both sides.
• Substitute the random values in the equation by using trial and error method, we can find the variable values.
• Replace those variable values in place of coefficients in the actual equation to get it balanced.

4. What does meant by balancing chemical equations?

Chemical Equation is defined as the symbolic representation of chemical reaction. A balanced equation is nothing but the equation where number of atoms in each element in reactants and products are same.

5. Balance SnO2 + H2 → Sn + H2O?

Write number of atoms in each element.

Left Hand Side has Sn = 1, O = 2, H = 2

Right Hand Side has Sn = 1, H = 2, O = 1

So, Oxygen atoms are not balanced at the products side.

Add 2 infornt of H2O and 2 before H2.

SnO2 + 2H2 → Sn + 2H2O

Again, check the number of atoms in each element

Left Hand Side has Sn = 1, O = 2, H = 2x2 = 4

Right Hand Side has Sn = 1, H = 2x2 = 4, O = 1x2 = 2

The equation is balanced.
