Question

d. CH 206 to (complete combustion) e. C6H12O6 to — (incomplete combustion) Net Ionic equations can be written for double displacement and single displacement reactions. All elements, precipitates, liquids, and lons not appearing on both sides of the equation are shown in a net ionic equation. 14. Write net ionic equations for the following unbalanced equations. a. Na3PO4 (aq) + SrCl2 (aq) → Sr3(PO4)2 (s) + NaCl (aq) b. Bi(NO3)2 (aq) + Na, SO4(aq) → Bi2(SO4)3 (s) + NaNO, (aq) c. AgNO, (aq) + Na CO2 (aq) → Ag,CO2 (s) + NaNO3 (aq) d. Pb(NO3). (aq) + K,Co, (aq) → Pb(CO3)2 (aq) + KNO, (aq) e. (NH4)2SO4 (aq) + Ca(OH)2 (aq) → NH3 (9) + H20 (1) + CaSO4(s)

Answer 1

14) Net ionic reaction don't involve any ions which are free on both reactant and product side.

a) 2PO₄^3-(aq) + 3Sr^{​​​​​2+}(aq) -> Sr_{​​​​​3}(PO₄)₂(s)

b) 2Bi ³⁺(aq) + 3SO₄^2-(aq) -> Bi₂(SO ₄)₃(s)

c) 2Ag⁺(aq) + CO ₃^2-(aq) -> Ag ₂CO₃(s)

d) No net reaction because all compound ionized.

e) 2NH₄⁺(aq) + SO₄^2-(aq) + Ca²⁺(aq) + 2OH^-(aq) -> 2NH₃(g) + 2H₂O(l) + CaSO ₄(s)
