The student provides a focused and detailed description of the main topic, clearly outlining the aim of the IA in the topic statement. Additionally, they present a well-structured introduction with relevant and focused background information. The chemistry is explained in a way that allows the reader to fully and easily understand it without the need for rereading, including the explanation of the enthalpy of combustion and important thermochemical terms. The methodology of the investigation is highly appropriate to the topic, focused on answering the research question, and includes appropriate steps to assure the relevancy and validity of the obtained results. However, the student should have further addressed ethical and environmental concerns, as these aspects are somewhat overlooked in the work.
