A student performed the five step reaction to produce copper (I) chloride as outlined in the CHM 125 lab manual. The ollowing reactions 1. Cu(s) + 2. 2 HNO3 (aq) + NaɔCO3 (s) 3. Cu(NO3)2 (aq) + NaCO3 (s) → CUCO; (s) + 2NaNO3 (aq) 4. CuCO3 (s) + 2 HCl (aq) 5. CuCl2 (aq) + Cu (s) The student weighed out 1.245 g of Cu (s) and added 5.3 mL of 15.8 M nitric acid. The student then added 3.911 g of 22CO3 (s) to the -5 answer the following questions: were performed: 4 HNO3 (aq) – + 2NO2 (g) Cu(NO3)2 (aq) +2 НаО (1) H2O (1) + CO, (g) +2 NaNO3 (aq) CuClh (aq) + H2O(l) + CO2 (g) 2 CuCl (s) mixture to carry out reactions 2 and 3 at the same time. Based on this information and the reactions a.Using equation 1 calculate the total number of moles of HNO; added. Next calculate how many moles of HNO; were ided in excess b. Based on the moles of HNO3 calculated in the previous step and also the number of moles of Cu(NO3)2 produced in the total mass of Na2CO3 needed for steps 2 and 3. Was the amount of Na,CO3 added in excess or action 1 calculate as it inadequate? By how much was it in excess or limited?
