On faucets and plumbing fixtures in areas with hard water, limescale accumulates over time. Limescale is primarily calcium carbonate (CACO3), and can be removed by reaction with vinegar (acetic acid): CaCO3(s) + 2 CH;COOH(aq) → Ca(CH;COO)2(aq) + CO2(g) + H2O(I) What mass in grams of CO2 could be produced by the complete reaction of 7.55 grams of calcium carbonate? g 1 4 C 7 9 +/- х 100 2.

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".
