课程名称：化学 概述：本课程旨在涵盖高级高中化学课程中的主题，与美国化学学会规定的标准主题相关联。该课程是未来高级化学Coursera课程的基础。课程内容包括原子结构、周期性趋势、化合物、反应和化学计量学、键合以及热化学等领域。 课程大纲：
第一部分
标题：第1周
描述：我们将学习原子内部的组成部分，特别关注电子。电子结构决定了元素的性质。因此，在这一系列课程结束时，您将了解每个元素中电子的位置。
第一部分
标题：第2周
描述：理解电子结构后，我们将能够利用周期表比较元素的原子大小和各种能量。最后，我们将探讨如何利用这些趋势预测元素的化学性质。
第一部分
标题：第3周
描述：了解原子结构后，我们将探讨原子如何结合形成分子或离子化合物。然后，我们将学习命名规则，确保化合物根据IUPAC规则命名。我们还将研究化合物的定量关系，包括化合物的摩尔质量和元素的质量百分比。
第一部分
标题：第4周
描述：我们将探讨化合物如何相互反应形成新物质，并书写平衡化学方程式以表示反应过程。我们将研究几种不同类型的反应，包括沉淀、酸碱、氧化还原和燃烧反应。
第一部分
标题：第5周
描述：本单元将深入探讨通过平衡化学方程式可确定的定量关系，以确定反应所需的相对物质量或生成的产品量。我们还将研究限制试剂和百分比产率，以解决化学反应的实际问题，因为可能会有剩余反应物和/或未完全生成的产品。
第一部分
标题：第6周
描述：本单元将深入研究分子化合物，分析其通过路易斯结构相互连接的方式。这些结构提供了关于键类型（单键、双键或三键）以及原子连接的信息。通过了解路易斯结构，我们还可以预测个体分子的三维几何形状。
第一部分
标题：第7周
描述：在本单元中，我们将学习热化学，即化学反应中热能转移（热量）的研究。我们将学习如何通过热量计来进行热测量，并使用各种方法计算热量转移。
Part: 1
Title:Week 1
Description:We will learn about the components inside the atom and look especially at the electrons. The electron structure determines the properties of the elements. So, by the end of this series of lessons, you will know for each elements where the electrons are located in the atom.
Part: 2
Title:Week 2
Description:Once we understand the electronic structure, we will be able determine how the periodic table can be used to compare the elements according to atomic size and various energies. We will conclude by seeing how these trends can be used to predict chemical properties of the elements.
Part: 3
Title:Week 3
Description:Now that we know the structure of an atom, we can explore how atoms combine to form either molecular or ionic compounds. Then we will learn the rules of nomenclature that ensure that a compound is named according to IUPAC rules. We will end this unit by looking at quantitative relationships for compounds including the molar mass of and mass percent of an element in a compound.
Part: 4
Title:Week 4
Description:We will explore how compounds react with one another to form new substances and then write balanced chemical equations to represent what is happening in a reaction. We will explore several different types of reactions including precipitation, acid-base, oxidation-reduction, and combustion reaction.
Part: 5
Title:Week 5
Description:This unit will delve into the quantitative relationships we can determine from a balanced chemical equation to determine the relative amounts of substances needed to react or the amount of products formed. We will also explore limiting reagents and percent yield to address practical aspects of chemical reactions because there may be leftover reactants and/or incomplete formation of products.
Part: 6
Title:Week 6
Description:This unit looks more in depth at molecular compounds to see how they are bonded together by looking at Lewis structures. These structures provide information about the types of bonds (single, double, or triple) as well as the connectivity of atoms. By knowing the Lewis structure, we can also predict the three-dimensional geometry of an individual molecule.
Part: 7
Title:Week 7
Description:In this unit, we will learn about thermochemistry, which is the study of the thermal energy transfer (heat) in chemical reactions. We will learn how these measurements of heat are made via calorimetry. Then, learn to calculate heat transfer using various methods.
This course is designed to cover subjects in advanced high school chemistry courses, correlating to the standard topics as established by the American Chemical Society. This course is a precursor to the Advanced Chemistry Coursera course. Areas that are covered include atomic structure, periodic trends, compounds, reactions and stoichiometry, bonding, and thermochemistry.
