SAT2化学知识解析：Chemical Yields

今天新航道SAT频道小编为大家整理了SAT化学知识解析：Chemical Yields，供大家参考，以下是详细内容。

There are three types of rate of return, you need to be familiar with the SAT II Chemistry Test: theoretical yield, actual yield, and percent yield. Here's a quick review of all of these mean to you. The theoretical yield of the reaction product formed, once the limiting reactant is completely consumed amount. This assumes perfect condition and gives a maximum amount. The actual production is actually what is actually happening in the process of the formation of reaction products. Finally, the percent yield is the ratio of the actual yield of the theoretical yield, can be obtained, this value is calculated using the following formula:

Let's go back to our last example, 28,116 grams calculate the theoretical yield. But what% rate of return, if you carry out this reaction, you actually collect 26,450 grams of ammonia? You will use the above formula. Here, it is plug in the numbers:
