Teaching Significant Figures: Simplified Approaches for Chemistry Educators
为什么教授有效数字至关重要 教还是不教有效数字? 在学年开始时,许多教师都面临一个熟悉的问题:我们应该教授有效数字吗?学生会根据过去的经验掌握这个通常很棘手的概念吗?这是许多教育工作者要么害怕要么很快忽略的话题。然而,当 […]The post Teaching Significance Figures: Simplified Approach for Chemistry Educators appeared first on High School/Honors/AP® Chemistry Resources | Viziscience.
在高中化学课上,我们了解到共价键涉及两个原子之间共享一对或多对电子。我们可以用图表表示这些成键电子对。电子位于两个原子的中间。对于同核键(两个原子是相同的元素),这大约是 […]The post Bonding Spectrum appeared first on High School/Honors/AP® Chemistry Resources | Viziscience.
What is mol rxn? Units in thermochemistry calculations.
什么是热化学单位“mol-rxn”? “mol-rxn”单位特别令人困惑,因为在大多数反应中,每种反应物和产物的化学计量不同。除非我们指的是一摩尔反应,即 6.022E23 个反应同时发生,否则根本不存在反应摩尔,而我们肯定不是。The post What is mol rxn? Units in hotchemistry computings. appeared first on High School/Honors/AP® Chemistry Resources | Viziscience.
