Write balanced net ionic equations for the reactions that occurred in the designated numbered boxes 1 through 8 in Table 2 on page 16 (do not include any reactions with HNO_3(aq). Be sure to include phase subscripts on all species in the balanced equations. (Each net ionic equation is worth 2 points, 16 pts total) Ba^+2(aq) + 2Cl^- (aq) rightarrow NR [reaction of Ba(NO_3)_2 (aq) with NaCl(aq)] 3Ba^2+ (aq) + 2 PO_4^3- (aq) rightarrow Ba_55(PO_4)_2(s) [reaction of Ba(NO_3)_2 (aq) with Na_3PO_4(aq)] Write the formula for the precipitate in box 3 of Table 2 and write a balanced net ionic equation for the reaction that occurred between this precipitate and 3 M HNO_3(aq) Make a copy of the table you made for the reactions of your 3 unknowns with the 4 reagents. Show all your observations. Identify the unknowns by unknown #. Write the formula of each anion contained in each of your 3 unknown. Write the molecular formula of the dissolved sodium salt in each of your 3 unknowns.
