Explanation:

Step1: Analyze reaction 1

HCl is a strong acid, dissociates completely in water: $\text{HCl} + \text{H}_2\text{O}
ightarrow \text{H}^+ + \text{Cl}^-$. Products: no acid/base/salt (ions only, but reaction type is strong acid dissociation).

Step2: Analyze reaction 2

$\text{CH}_3\text{COOH}$ is a weak acid, dissociates partially (double arrow): $\text{CH}_3\text{COOH} + \text{H}_2\text{O}
ightleftharpoons \text{CH}_3\text{COO}^- + \text{H}^+$. Reaction type: weak acid dissociation.

Step3: Analyze reaction 3

NaOH is a strong base, dissociates completely: $\text{NaOH} + \text{H}_2\text{O}
ightarrow \text{Na}^+ + \text{OH}^-$. Reaction type: strong base dissociation.

Step4: Analyze reaction 4

$\text{NH}_3$ is a weak base, reacts partially with water: $\text{NH}_3 + \text{H}_2\text{O}
ightleftharpoons \text{NH}_4^+ + \text{OH}^-$. Reaction type: weak base dissociation.

Step5: Analyze reaction 5

Acid ($\text{HNO}_3$) + base ($\text{NaOH}$) → water + salt ($\text{NaNO}_3$): $\text{HNO}_3 + \text{NaOH}
ightarrow \text{H}_2\text{O} + \text{NaNO}_3$. Reaction type: neutralization; product $\text{NaNO}_3$ is a salt.

Answer:

1. a. strong acid dissociation; b. (no acid/base/salt, ions only)
2. a. weak acid dissociation; b. (no acid/base/salt, ions only)
3. a. strong base dissociation; b. (no acid/base/salt, ions only)
4. a. weak base dissociation; b. (no acid/base/salt, ions only)
5. a. neutralization; b. $\text{NaNO}_3$ (salt)
