The aqueous solution containing 1.56 grams of BaCl2 is reacted by mixing with the aqueous solution containing 3.825 grams of AgNO3. The reaction mixture is allowed to stand for a while and then filtered. The obtained solid (AgCl) is dried and weighed and it is determined that it comes to 1.82 grams. 2 (solution) + 23 (solution) 2() + (3)(solution) a) Specify the limit component and the excess component. Calculate the percentage of excess component. b) Calculate the degree of completion of the reaction. BaCl2: 208 (g/mol), AgNO3: 170 (g/mol), AgCl: 143.5 (g/mol) (celebrate an energy)
