![**Equilibrium Reactions Involving Ammonia and Water**
Complete the equations for the following equilibria, calculate \( K_c \) for each reaction and express its value in proper scientific notation.
**(a) Ammonia (acting as a base) reacts with water (acting as an acid):**
- **Equilibrium Reaction:**
\(\text{NH}_3 + \text{H}_2\text{O} \rightleftharpoons\)
- **Equilibrium Constant (\( K_c \)):**
\[ \boxed{} \]
**(b) Ammonia (acting as an acid) reacts with water (acting as a base):**
- **Equilibrium Reaction:**
\(\text{NH}_3 + \text{H}_2\text{O} \rightleftharpoons\)
- **Equilibrium Constant (\( K_c \)):**
\[ \boxed{} \]
**Species and \( pK_a \) values:**
\[
\begin{array}{|c|c|}
\hline
\text{Species} & pK_a \\
\hline
\text{NH}_3 & 35 \\
\text{NH}_4^+ & 9.25 \\
\hline
\end{array}
\]
This exercise involves completing and analyzing the given equilibrium reactions where ammonia acts in different roles, either as a base or an acid. The \( pK_a \) values of the involved species are provided to assist in these calculations.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7a6c3af6-91f1-478b-99db-a0b0fd9518f2%2Fee4e6fe1-d3e6-4566-b05d-0d6fcfc4c672%2F63mhvh_processed.png&w=3840&q=75)
