**课程名称：** 化学：揭秘化学计量 **课程概述：** 您是否觉得化学计量令人望而却步？您是否不确定何时需要使用化学计量，更不用说如何解决化学计量问题了？本课程正是为您量身打造！我们将从识别化学计量问题入手。当您拿到一个待解决的问题时，第一步是知道使用哪种工具。然后，我们将学习如何为各种问题寻找合适的摩尔比。接下来，我们将只使用摩尔来处理简单的化学计量问题。一旦我们熟练掌握了摩尔的使用，我们将进阶到以克为单位的起始和结束计算。我们将预测会生成多少产物，以及需要多少反应物。在掌握了简单的化学计量之后，我们将学习限制性反应物。与之前一样，我们首先学习区分简单的化学计量问题和限制性反应物问题。然后，我们将学习如何识别限制性反应物。一旦掌握了这些技能，我们将利用这些信息来预测产物的生成量以及反应完成后剩余的过量反应物的量。最后，我们将学习计算反应的百分收率。每个部分都配有示例和供您独立练习的题目。每个部分之后都会有简短的测验，以帮助最大限度地提高学习效果和信息记忆。您也可以掌握化学计量！
Does stoichiometry feel like an insurmountable obstacle? Are you unsure when you need to use stoichiometry, much less how to do stoichiometry problems? This course is for you! We start with learning to recognize a stoichiometry question. When you have a problem to solve, the first step is to know which tool to use. Then, we work on finding appropriate mole ratios for various questions. Next, we tackle simple stoichiometry using moles only. Once we are comfortable using moles, we move on to starting and finishing problems in grams. We will predict how much product is formed as well as how much reactant is needed. After mastering simple stoichiometry, we will move onto limiting reactants. Just like before we start with learning to recognize the difference between a simple stoichiometry question and a limiting reactant questions. Then, we will learn how to identify the limiting reactant. Once those skills are mastered, we will use that information to predict products and how much excess reactant remains when a reaction is complete. Finally, we will learn to calculate the percent yield of the reaction. Each section is accompanied by examples and problems for you to work on your own. A short quiz follows each section to help maximize learning and retention. You can do stoichiometry!
