Data of the Report for EESC USP – General and Experimental Chemistry 7500017

The Department of Chemistry at the School of Engineering, University of São Carlos (EESC USP), offers a comprehensive curriculum in chemistry, combining theoretical knowledge with hands-on laboratory practice. The course code 7500017, titled General and Experimental Chemistry, focuses on providing students with a deep understanding of essential chemistry principles and experimental techniques. This report covers the practical aspects and key data observed throughout the course, aiding in the development of students’ problem-solving and analytical skills.

Course Overview

The course General and Experimental Chemistry is designed to help students understand fundamental concepts of chemistry through lectures and practical laboratory experiments. Students are introduced to topics such as:

• Atomic structure and periodicity
• Chemical bonding and molecular structure
• Thermodynamics and kinetics
• Organic chemistry basics
• Laboratory safety protocols
• Experimental techniques in chemistry

The practical sessions offer students the chance to apply theoretical knowledge in real-world scenarios, allowing them to better understand chemical processes and reactions.

Experimentation and Data Collection

Throughout the semester, students engage in various experiments that involve chemical reactions, measurements, and observations. Some common types of experiments include:

• Titration: Determining the concentration of an unknown acid or base.
• Calorimetry: Measuring the heat released or absorbed during chemical reactions.
• Synthesis of compounds: Reactions to form specific chemical compounds and their analysis.
• Stoichiometric calculations: Using data from experiments to calculate quantities of reactants and products.

Data collected during these experiments is crucial for the interpretation of results. Typical data might include:

1. Quantitative measurements: Masses of reactants and products, volumes of liquids used, and concentration values.
2. Temperature measurements: Changes in temperature during reactions, especially in exothermic or endothermic processes.
3. Reaction times: Observations of how long certain reactions take to reach completion.
4. Observations: Visual changes, such as color changes, precipitate formation, or gas evolution.

Data Analysis

Data analysis involves using mathematical and chemical principles to interpret experimental results. For example, in a titration experiment, students use the data of the volume of titrant used and its concentration to calculate the unknown concentration of the analyte.

The following steps are usually involved in the data analysis:

1. Calculation of moles: Using molar ratios from balanced chemical equations.
2. Graphing and plotting data: For example, creating graphs to represent reaction rates or temperature changes.
3. Error analysis: Identifying sources of error in experiments and determining their impact on results.

Conclusion

The General and Experimental Chemistry course at EESC USP (7500017) provides students with an essential understanding of both theoretical chemistry and practical laboratory work. Through the experiments and the data collection process, students gain valuable experience that enhances their analytical and problem-solving skills. This combination of learning prepares them for advanced chemistry topics and provides a solid foundation for future studies in various fields of science and engineering.

By focusing on accurate data collection and analysis, students not only deepen their knowledge of chemistry but also learn to apply this knowledge in real-world contexts, preparing them for professional careers in the scientific community.
