Question

Quizplus · Accepted Answer

The first blank is asking for a comparative term, meaning we need to compare pulling electrons from water to pulling electrons from hydrogen sulfide. The second blank is asking for a term that describes the strength of affinity for electrons of the sulfur and oxygen atoms. The sentence states that the sulfur atom in hydrogen sulfide has a much higher affinity for its electrons than the oxygen atom in water, meaning it is harder to pull electrons from hydrogen sulfide than water. Therefore, the best answer is A) harder, lower.
