A10.0.3455 g of A CO, (A is an alkaline metal) was reacted with 50.0 mL 0.200 M hydrochloric acid (HCI) to form ACl(aq), H2O(l) and CO2(9): A2CO3(aq)+2HCl(aq) → 2Cl(aq)+CO2(9)+H306) The excess of HCI (remained after all A2CO, is reacted) requires 50.0 ml of 0.100 M NaOH aqueous solution to be neutralized. After determining the molar mass of A,COs, identify A A. Li B. Cs C. K D. Na E. Rb
