Calcium trioxocarbonate (IV) reacts with trioxonitrate (V) acid according to the equation below; CaCO3 + 2HNO3 → Ca(NO3)2 + H2O + CO2 If 20g of the trioxocarbonate (V) reacted completely with the acid, calculate the number of moles of the moles of the trioxonitrate (V) acid that reacted [ C =12 , O = 16, Ca =40] (b) Consider the volume of HCl gas that can be obtained at stp from 5.85g of sodium chloride[ H =1 , Na = 23, Cl =35.5]
