Write balanced molecular and net ionic equations for the reactions of (c) hydrobromic acid with magnesium (d) acetic acid, CH3COOH, with zinc.

검증된 단계별 안내
1
Identify the reactants: Acetic acid (CH3COOH) and zinc (Zn).
Write the unbalanced molecular equation: CH3COOH + Zn → Zn(CH3COO)2 + H2.
Balance the molecular equation: 2 CH3COOH + Zn → Zn(CH3COO)2 + H2.
Write the total ionic equation by breaking all soluble compounds into their ions: 2 CH3COOH (aq) + Zn (s) → Zn^2+ (aq) + 2 CH3COO^- (aq) + H2 (g).
Identify and remove the spectator ions (if any) to write the net ionic equation: Zn (s) + 2 CH3COOH (aq) → Zn^2+ (aq) + 2 CH3COO^- (aq) + H2 (g).

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Acid-Base Reactions

Acid-base reactions involve the transfer of protons (H+) between reactants. In this case, acetic acid (CH3COOH) acts as a weak acid, donating a proton to a base. Understanding the nature of acids and bases is crucial for predicting the products of the reaction and writing balanced equations.

Oxidation-Reduction Reactions

Oxidation-reduction (redox) reactions involve the transfer of electrons between substances. In the reaction between acetic acid and zinc, zinc is oxidized as it loses electrons, while acetic acid is reduced. Recognizing the oxidation states of the elements involved helps in balancing the overall reaction.

Ionic Equations

Ionic equations represent the species that are actually involved in a chemical reaction, excluding spectator ions. For the reaction of acetic acid with zinc, writing the net ionic equation requires identifying the ions that participate in the reaction and omitting those that do not change during the process. This simplifies the representation of the chemical change.
