Limescale that builds up in showers, kettles, and pipes is often primarily composed of calcium carbonate.One limescale remover contains sulfamic acid (H3NSO3) , which can be considered to be a strong monoprotic acid.Which reaction summarizes the action of sulfamic acid on limescale?
A) H + (aq) + H2NSO3 - (aq) + CaCO3 (s) HCO3 - (aq) + HNSO32 - (aq) + Ca + (aq)
B) 3H + (aq) + NSO3 - (aq) + CaCO3 (s) Ca 2 + (aq) + HSO3 - (aq) + NO2 (g) + CO2 (g) +H2O (l)
C) 2H + aq) +2 H2NSO3 - (aq) + CaCO3 (s) CO2 (g) +2 H2NSO3 - (aq) + Ca 2 + (aq) +H2O (l)
D) 3H + (aq) + NSO33 - (aq) + CaCO3 (s) Ca 2 + (aq) + NSO33 - (aq) + CO2 (g) + 3 HNO2 (aq)
E) 3H+(aq) + NSO3 - (aq) + CaCO3 (s) CaS(s) + HCN(g) +3H2O(l)
