Before starting the experiment they perform the following calculations to predict the maximum (theoretical) yield of zinc sulfide that could be produced. They obtain an actual yield of 8.25 grams of zinc sulfide. Calculate their percent yield to one decimal place.arrow_forward

Relatives of the patient tell you that he may have ingested rat poison. Therefore, you have his stomach pumped to verify this and to determine the cause of death. One of the more logical things to do would be to attempt to isolate the agent that caused death and perform chemical analyses on it. Assume that this was done, and the analyses showed that the isolated chemical compound contained, by weight, 60.0% potassium, 18.5% carbon, and 21.5% nitrogen.
