Use the following information to answer the next the questions prot the Double Replacement Reaction In a chemical analysis, 5.00 g of silver nitrate in solution reacted with 20 got sodium chloride in solution Alter the reaction was como the mature was thered and the mass of dried precipitate was measured to be 3.0 div drox 47. The excess roagentis sliver nitrate ventu magn sodium chloride sodium nitrate silver chondo aion soluti 48. The mass of excess reagent that is left over etter the reaction is complete is 1729 4229 V. the 0.80 9 SATP 2489 tro Dec Numeric Response 10. The theoretical yeld of precipitate expected in the above reaction Your answer operty

Answer 1

NO 3 + NaCl The reaction is as as follows in AgNO3 → NaNO3 lag) + Agulle's 5.00g 3.69 g Moles of Ag No 3 reacting = given weight Molecular weight 4.20g 5.00 169.87 = 0.02943 Moles of Nach reating given weight Molecuber weight 4.20 58.44 0.07186 Sinces 1 meb of Ag Noz duets with 1 mele of

0.02943 mol of Ag No3 reacts with 0.07186 of Ag Nall. mol of Therefore, Ag Noz_is_limi imiting reagent and reagent. Nach is excess 0.02 943 mol o.o2g4 3 molof Nach Since, 1 mole of AgNO3 reacts with I mole of Ag A • NO₃ should react with reagent left Mans of BLUES reagent left = mele. X Molemler ut Mole of excess 0.07186 -0.02.943 = 0.0424.3 = 0.14243 x 58,44 2.4796 = 2.48 g .. 1 mol of AgNO3 reacts with Imol of Nall to give 1 mol of Ag Cl. ;. 0.08948 med of fqnoz marts with 0: 02943 wall to gece 0.62943_mel of of Ag Cl.
