Question

1. volcanoes on jupiters moons emit hydrogen sulfide gas and sulfur dioxide gas. these gases react to form gaseous products, as represented by the following equation. 16h₂s(g) + 8so₂(g) → 16h₂o(g) + 3s₈(g) which of the following rows identifies the reducing agent and the substance being oxidized when the gases react? select one: reducing agent: h2s(g), substance being oxidized: h2s(g) reducing agent: so2(g), substance being oxidized: h2s(g) reducing agent: h2s(g), substance being oxidized: so2(g) reducing agent: so2(g), substance being oxidized: so2(g)

Explanation:

Step1: Recall definition of reducing agent

A reducing agent is a substance that donates electrons and gets oxidized in a chemical reaction.

Step2: Analyze oxidation - state changes

In the reaction \(16H_2S(g)+8SO_2(g)
ightarrow16H_2O(g) + 3S_8(g)\), in \(H_2S\), the sulfur has an oxidation - state of - 2. In the product \(S_8\), the oxidation - state of sulfur is 0. Sulfur in \(H_2S\) is oxidized. Since \(H_2S\) is oxidized, it is the reducing agent. The substance being oxidized is also \(H_2S\).

Answer:

Reducing Agent: \(H_2S(g)\), Substance Being Oxidized: \(H_2S(g)\)
