Question
**Topic: Writing Net Ionic Equations**

In this exercise, you will write net ionic equations for the following molecular equations. When completing these equations, use the lowest possible coefficients and be sure to specify states such as (aq) for aqueous or (s) for solid. If you do not need a box, leave it blank. Use \( \text{H}^+ \) to represent the hydronium ion.

**a.** \( \text{HBr(aq)} + \text{NH}_3\text{(aq)} \rightarrow \text{NH}_4\text{Br(aq)} \)

- **Net Ionic Equation:**

(Reactant ions and products are left blank here for educational purposes.)

**b.** \( 2\text{HI(aq)} + \text{Ba(OH)}_2\text{(aq)} \rightarrow 2\text{H}_2\text{O(l)} + \text{BaI}_2\text{(aq)} \)

- **Net Ionic Equation:**

(Reactant ions and products are left blank here for educational purposes.)

**c.** \( \text{Pb(NO}_3\text{)}_2\text{(aq)} + 2\text{NaBr(aq)} \rightarrow \text{PbBr}_2\text{(s)} + 2\text{NaNO}_3\text{(aq)} \)

- **Net Ionic Equation:**

(Reactant ions and products are left blank here for educational purposes.)

**d.** \( \text{MgCO}_3\text{(s)} + \text{H}_2\text{SO}_4\text{(aq)} \rightarrow \text{MgSO}_4\text{(aq)} + \text{H}_2\text{O(l)} + \text{CO}_2\text{(g)} \)

- **Net Ionic Equation:**

(Reactant ions and products are left blank here for educational purposes.)

**Note**: The boxes in the problems above are meant for you to fill in the separated ions and any spectators that cancel out. The final goal is to represent the actual chemical change taking place. Use your knowledge of solubility rules and ion charges to determine which elements or compounds remain in the solution and which form precipitates.
