Answer to Question #85249 in General Chemistry for kiah

Question

1. Write the balanced NET ionic equation for the reaction when Li₂SO₄ and Ca(NO₃)₂ are mixed in aqueous solution. If no reaction occurs, write only NR. 2. Write the balanced NET ionic equation for the reaction when aluminum nitrate and potassium iodide are mixed in aqueous solution. If no reaction occurs, write only NR. 3. Write the balanced NET ionic equation for the reaction when Al(NO₃)₃ and Na₃PO₄ are mixed in aqueous solution. If no reaction occurs, write only NR.

Answer 1

Answer:

1) Ca(NO3)2 + Li2SO4 = 2LiNO3 + CaSO4

Ca2+ + 2NO3- + 2Li+ + SO42- = 2Li+ + 2NO3- + CaSO4

Ca2+ + SO42- = CaSO4

2) Al(NO3)3 + 3KI = AlI3 + 3KNO3 - reversible process

3) Al(NO3)3 + Na3PO4 = AlPO4 + 3NaNO3

Al3+ + 3NO3- + 3Na+ + PO43- = AlPO4 + 3Na+ + 3NO3-

Al3+ + PO43- = AlPO4
