How They Are Represented

Chemical reactions are shows with the help of symbols, an arrow and additional information about the reaction written in short in the form of a chemical equation

We should keep in mind that all chemical equations must subside with the Law of Conservation of Mass i.e., the numbers of atoms of each element seperately should be equal on the LHS and RHS of the equation.

For example– Fe2O3 + 2Al —> Al2O3+ 2Fe ab h
