### Problem 14
# Explanation:
## Step1: Identify reaction pattern
In the reaction $\ce{Na3PO4 + 3KOH -> 3NaOH + K3PO4}$, the cations ($\ce{Na+}$ and $\ce{K+}$) and anions ($\ce{PO4^{3-}}$ and $\ce{OH-}$) switch places between the two compounds.
## Step2: Classify reaction type

# Answer: Synthesis

### Problem 23
# Explanation:
## Step1: Identify reaction pattern
In $\ce{SeCl6 + O2 -> SeO2 + 3Cl2}$, a single element ($\ce{Cl}$ from $\ce{SeCl6}$) is replaced by another element ($\ce{O}$) in the compound, and $\ce{Cl2}$ is a product. Wait, more accurately, $\ce{SeCl6}$ reacts with $\ce{O2}$, and $\ce{Cl}$ is replaced (in a sense) and forms $\ce{Cl2}$, while $\ce{Se}$ combines with $\ce{O}$ to form $\ce{SeO2}$. But the key is that one element (O) replaces another (Cl) in the compound $\ce{SeCl6}$, and Cl is released as $\ce{Cl2}$. However, another way: the reaction is a single replacement? Wait, no, let's re - examine. The reactants are $\ce{SeCl6}$ and $\ce{O2}$, products are $\ce{SeO2}$ and $\ce{Cl2}$. So $\ce{O}$ from $\ce{O2}$ replaces $\ce{Cl}$ in $\ce{SeCl6}$, and $\ce{Cl}$ forms $\ce{Cl2}$. So this is a single replacement reaction? Wait, no, single replacement is usually one element replacing another in a compound. Here, $\ce{SeCl6}$ is a compound, $\ce{O2}$ is an element. $\ce{O}$ replaces $\ce{Cl}$ in $\ce{SeCl6}$, and $\ce{Cl}$ is displaced as $\ce{Cl2}$. So it is a single replacement reaction? Wait, alternatively, decomposition? No, decomposition is one compound breaking down. Here, it's a reaction between a compound and an element. So single replacement: an element ($\ce{O2}$) replaces another element ($\ce{Cl}$) in a compound ($\ce{SeCl6}$), and the displaced element forms a diatomic gas. So yes, single replacement. Wait, but let's check the definition again. Single replacement: $\ce{A + BC -> AC + B}$. Here, $\ce{O2}$ (A) + $\ce{SeCl6}$ (BC) -> $\ce{SeO2}$ (AC) + $\ce{Cl2}$ (B, since Cl is displaced and forms $\ce{Cl2}$). So that fits. So reaction type is single replacement? Wait, no, maybe I made a mistake. Wait, $\ce{SeCl6 + O2 -> SeO2 + 3Cl2}$. Let's see the oxidation states. Se in $\ce{SeCl6}$ is +6, in $\ce{SeO2}$ is +4. O in $\ce{O2}$ is 0, in $\ce{SeO2}$ is - 2. Cl in $\ce{SeCl6}$ is - 1, in $\ce{Cl2}$ is 0. So it's a redox reaction. But the type: single replacement. Because an element (O) replaces another element (Cl) in a compound (SeCl6), and the displaced element (Cl) is released as a free element ($\ce{Cl2}$). So yes, single replacement.
## Step2: Classify reaction type
Based on the pattern of an element replacing another in a compound, this is a single replacement reaction.
