What is a Lewis Structure?

A Lewis structure is a structural representation of a molecule where dots are used to show electron positions around atoms. It helps in predicting molecular geometry and bond formation.

How to Calculate Stoichiometry

To calculate stoichiometry, balance the chemical equation first. Then convert the known mass of the reactant to moles, use the molar ratio to find the target moles, and convert back to mass.
