What should I do if the reactants have the same number of moles? 2, were available, only 1 mol of CaCO. yield = "60 g CaCO"_3 ("1 mol CaCO"_3)/("100.0 g CaCO"_3) "1 mol CaO"/("1 When aqueous hydrochloric acid is added, calcium chloride, carbon dioxide and water are formed. The theoretical yield of the precipitate is mass of Mol ratio : 1:1 ratio of CaCO 3 CaCO3 to CaCl 2 CaCl2 * CaCl 2 CaCl2 = 0.01125851 mol Step 6 : Calculate the molar mass of Calcium Chloride M= Ca + ( 2 ) Cl = 40.08 + 2 (35.453 ) = 110.986 Na2CO3(aq) + CaCl22H2O CaCO3(s) + 2NaCl(aq) + 2H2O(aq) It has been previously determined that : there are 1.50 grams of CaCl22H2O there are .0102 moles of pure CaCl2 and Question 3 7.7 points Save Answer The reaction between Na2CO3 and CaCl2 actually produced 25.6 g of CaCo3. Answer: Calcium Carbonate + Hydrogen Chloride Calcium Chloride + Water + Carbon Dioxide. wikiHow is where trusted research and expert knowledge come together. 5 23. Na2CO3 + CaCl2 ---> CaCo3 + 2NaCl O 100.96 58.0 96 84.996 73.1 96 37.9 96 < You S ort sheet . Moles =1/147.01 which equals 6.8*10-3 mol. Rinse the beaker containing Na2CO3 with 2-3 mL of distilled water and transfer the rinse to the beaker containing the CaCl22H2O. Substitute Coefficients and Verify Result. changed during the reaction.
