The student does not provide a focused and detailed description of the main topic, as the title statement is missing. Additionally, the research question lacks specificity regarding the concentrations used in the investigation. The background information is not adequately relevant, as the notation of the gasohol mixtures is not explained. Furthermore, the chemistry involved is not sufficiently discussed, particularly the method for calculating the enthalpy change. While the methodology is appropriate and includes steps to ensure the validity of results, it fails to clearly identify the range of independent variables. The student does not demonstrate full awareness of safety hazards or ethical concerns related to the experiment, although they do show awareness of environmental issues.
