The net ionic equation for the reaction between aqueous (NH₄)₃PO₄ and aqueous Zn(NO₃)₂ to form solid Zn₃(PO₄)₂ and aqueous NH₄NO₃ is:
- PO₄³⁻ (aq) + Zn²⁺ (aq) ----> Zn₃(PO₄)₂ (s)
<h3>What are net ionic equations?</h3>
Net ionic equations are equations that show only the reactant ions that are involved in the formation of a non-ionic product.
In a net ionic equation, the spectator ions or the ions which appear on both sides of the reaction are eliminated.
Considering the given reaction between aqueous (NH₄)₃PO₄ and aqueous Zn(NO₃)₂ to form solid Zn₃(PO₄)₂ and aqueous NH₄NO₃:
The molecular equation is given below:
(NH₄)₃PO₄ (aq) + Zn(NO₃)₂ (aq) ----> Zn₃(PO₄)₂ (s) + NH₄NO₃ (aq)
The net ionic equation is:
PO₄³⁻ (aq) + Zn²⁺ (aq) ----> Zn₃(PO₄)₂ (s)
The product Zn₃(PO₄)₂ is insoluble and is obtained as a precipitate.

Answer:
Optical Atomic Spectroscopy
Explanation:
...
<span>C6H12 = 6x12 + 6x1 = 78.
The equation indicates that 2x78 = 156g benzene will produce 6542kJ.
Using proportions you can then calculate that
x/6542kJ = 7.9g / 156g
x = 331.3kJ = 331300J.
heat = mass x ΔT x 4.18J/g°
ΔT = 331300J / (5691g x 4.18J/g°) = 13.9°
final temp = 21 + 14° = 35°C</span>
