How do we balance an equation ?? Give any 2 examples
Answers
In general, to balance an equation, here are the things we need to do:
- Count the atoms of each element in the reactants and the products.
- Use coefficients; place them in front of the compounds as needed.
Balanced chemical equation :
A balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side.
How to balance a chemical equation :
To balance a chemical equation, start by writing down the number of atoms in each element, which is listed in the subscript next to each atom. Then, add coefficients to the atoms on each side of the equation to balance them with the same atoms on the other side.
Example 1. => C5H12 + O2 ---> CO2 + H2O
Example 2. => Zn + HCl ---> ZnCl2 + H2

Some examples of balanced chemical equation :
For example, hydrogen gas (H2) can react (burn) with oxygen gas (O2) to form water (H20).
Example 6. C2H6 + O2 ---> CO2 + H2O.
