2. What net ionic equation describes the reaction that occurs when Al2(SO4)3(aq) and Na3PO4(aq) are mixed together? 3Na+(aq) + PO43-(aq) - 3Naso (s) + A13+ (aq)
A13+(aq) + PO43-(aq) - AlPO4(s)
35042-(aq) + 3Na+(aq) - Naso,(s)
Al3+ (aq) + PO43-(aq) + 350,2-(aq) - 3 AlPO4(s) + 3Na+(aq)

Asample of ammonia reacts with oxygen as shown. 4nh3(g) + 5o2(g) 4no(g) + 6h2o(g) what is the limiting reactant if 4.0 g of nh3 react with 8.0 g of oxygen? o2 because it produces only 0.20 mol of no. nh3 because it produces only 0.20 mol of no. o2 because it produces two times less no than nh3. nh3 because it produces three times more no than o2.
