$\texttt{WRITING A CHEMICAL EQUATION}$

$<u>Is there any other shorter way for representing chemical equations?</u>$

Chemical equations can be made more concise and useful if we use chemical formulae instead of words. A chemical equatiom represents a chemical reaction. For example:

Oxygen and magnesium oxide

The above word-equation can be written as-

$\textbf{\red{Mg + O2 ----> MgO}}$

Count and compare the number of atoms of each element on the LHS and RHS of the arrow.

$<u>Is the number of atoms of each element same on both of the sides?</u>$

If not then the equation is unbalanced because the mass is not the same on both sides of the equation. Such a chemical equation is skeletal chemical equation for a reaction.
