Glass is a mixture of several compounds, but a major constituent of most glass is calcium silicate, CaSiO3. Glass can be edged by treatment with hydrogen fluoride: HF Attacks the calcium silicate of the glass, producing gaseous and water soluble products (which can be removed by washing the glass). for example, the volumetric glassware and chemistry laboratories is often graduated by using this process. Balance the following equation for the reaction of hydrogen fluoride with calcium silicate. (Use the lowest possible coefficients.)

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
