下面澳际小编下面为大家搜集整理了SAT2化学知识解析:Chemical Yields的相关介绍,供大家参考和借鉴。
There are three types of yields you’ll need to bamiliar with for the SAT II Chemistry test: theoreticalyields, actual yields, and percent yields. Here’s a quickreview of what all of these mean to you. Thetheoretical yield of a reaction is the amount ofproduct formed once the limiting reactant has beencompletely consumed. This assumes perfectconditions and gives a maximum amount. The actualyield is what actually occurs in the course of thereaction—how much product is actually formed. Finally, the percent yield is the ratio of theactual yield to the theoretical yield, and you can get this value using the following formula:
Going back to our last example, the 28,116 grams you calculated would be the theoreticalyield. But what would the percent yield be if you performed this reaction and you actuallycollected 26,450 grams of ammonia? You would calculate it using the above formula. Here it iswith the numbers plugged in:
以上就是SAT2化学知识解析:Chemical Yields的详细内容,大家在备考SAT2化学考试时候,可以进行更加细致的复习。澳际小编祝大家都能取得理想的SAT考试成绩!
