摘要

摘要限制反应物是任何反应中的一个关键因素。学生们发现这是一个棘手的话题。目前的研究旨在进行一项小厨房实验,在该实验中,学生将遵循教学程序,在自学过程中确定限制反应物。这项研究采用了实验方法。在C++中开发了一个程序,作为确定极限反应物的有效工具。该研究得出的主要结果揭示了平衡方程在获得正确摩尔比方面的重要性。还注意到,在一个特定的平衡方程中,摩尔比的相似性可能会错误地导致错误的假设。

A simple pedagogical limiting reactant kitchenette experiment including a simple algorithm
Abstract Limiting reactants is a crucial factor in any reaction. Students found it a tricky topic. The current study has intended to conduct a kitchenette experiment, in which a student will follow the instructional procedure to determine a limiting reactant in a self-learning process. The study has adopted an experimental approach. A program was developed in C++ as an efficient tool to determine the limiting reactant. The major outcomes drawn from the study have enlightened the significance of a balanced equation in obtaining the correct molar ratio. It has also been noted that molar ratio similarity in a particular balanced equation can wrongly lead to an erroneous assumption.
