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) 3 H+(aq) + NSO3-(aq) + CaCO3(s) Ca2+(aq) + HSO3-(aq) + NO2(g) + CO2(g) + H2O(
)
C) 2 H+(aq) + 2 H2NSO3-(aq) + CaCO3(s) CO2(g) + 2 H2NSO3-(aq) + Ca2+(aq) + H2O(
)
D) 3 H+(aq) + NSO33-(aq) + CaCO3(s) Ca2+(aq) + NSO33-(aq) + CO2(g) + 3 HNO2(aq)
E) 3 H+(aq) + NSO3- (aq) + CaCO3(s) CaS(s) + HCN(g) + 3 H2O(
)
