How to do balancing chemical equations homework

Balancing chemical equations:

"The symbolic representation of the chemical reaction" using the symbols for denoting the reactants and the product is called as A chemical equation. The reactant involved in the reaction are placed on the left side and the product are present on the right-side.  

Method 1: Doing a Traditional Balance

Step 1: First write the chemical equation representing the reaction.

Step 2: Next find or identify the  number of atoms present in each of the element

Step 3: Start balancing with the single elements  

Step 4: Use a coefficient to balance the element such that the amount of substance present on both the sides are equal.  

Method 2: Completing an Algebraic Balance

Step 1:Write down the given equation.

Step 2:Assign a letter to each substance.

Step 3:Check the number of each element found on both sides, and set those equal to each other.

Step 4:Solve this system of equations to get the numeric value for all the coefficients.
