Explanation:

Step1: Analyze Acid Ionization Steps

Ionization starts first (step 68: 1). Then, the acid donates a H⁺, forming a hydrogen ion (step 66: 2). Next, the H⁺ bonds with H₂O (step 69: 3). Finally, H₃O⁺ (hydronium) is formed (step 67: 4). So order: 2, 4, 1, 3.

Step2: Match Scientists with Contributions

• (70) Faraday (b) - electrode particle conversion.
• (71) Arrhenius (g) - traditional acid def (ionizes to H⁺).
• (72) Ira Remsen (a) - Johns Hopkins chem dept.
• (73) Gilbert Lewis (h) - electron - pair acid def.
• (74) Lavoisier (e) - acid has oxygen.
• (75) Brønsted - Lowry (f) - proton - donor acid.
• (76) Justus von Liebig (d) - acid has H, reacts with metals.
• (77) Sir Humphry Davy (c) - H is essential in acid.

Step3: Match Reactions with Acid Types

• (78) HA → H⁺: Brønsted - Lowry (b) (proton donor).
• (79) A ← electron pair: Lewis acid (c) (accepts electron pair).
• (80) HA(aq) → H⁺: Traditional acid (a) (ionizes to H⁺).
• (81) Zn + H₂SO₄ → H₂: Traditional acid (a) (metal - acid reaction for H₂).
• (82) HCl + NH₃ → NH₄⁺ + Cl⁻: Brønsted - Lowry (b) (HCl donates H⁺ to NH₃).
