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 CH3COOH(aq) → Ca(CH3COO)2(aq) + CO₂(g) + H₂O(l)
What mass in grams of CO₂ could be produced by the complete
reaction of 4.55 grams of calcium carbonate?
