Expert School Science Tutor with a Passion for Health and Earth Sciences Mastery

Aashima and a student from Rochester Institute of Technology reviewed biodiesel production, covering the chemical reaction, manufacturing steps, advantages, disadvantages, and green chemistry principles related to catalyst choice. They then discussed addition polymers, including reasons for their widespread use, the addition polymerization process, and methods for identifying monomers and substituents in polymers like PVC, polystyrene, and Teflon. The next lesson will cover petroleum-based feedstocks, condensation polymers, polyamides (nylon and Kevlar), and amino acids/proteins.

The tutor and a student from Dallas College - Grand Prairie Campus covered the basics of polymers, including their definition, types (addition, condensation, natural, synthetic), properties, structural dependence, and applications. They also discussed specific examples like polyethylene, PVC, polystyrene, Teflon, nylon, polyester, proteins, starch, cellulose, and natural rubber. The learner will send the tutor the learning goals for the next PowerPoint on polyamides for the next lesson.

Aashima and Iliana delved into the chemistry of cleaning agents, discussing the cleaning action of soap, the effects of hard water on its effectiveness, and the advantages of detergents. Their organic chemistry discussion also covered anionic, cationic, and nonionic detergents, including their structures and properties. Iliana will send Aashima the polymer details for their next lesson, which is scheduled for next week.

Aashima and Iliana engaged in a comprehensive organic chemistry lesson, delving into saponification and ester hydrolysis. Their discussion covered real-life applications, the underlying reaction mechanisms, and the intricate structure of soaps. They also reviewed triglycerides and their essential role in the soap formation process. Given Iliana's upcoming practical assessment, they scheduled their next lesson to focus on alcohol differentiation and polymers.

In their recent organic chemistry lesson, Aashima and Iliana thoroughly reviewed reactions involving carboxylic acids and alcohols, covering processes such as halogenation, anhydride formation, and oxidation. Their discussion then shifted to the crucial concepts of esterification and saponification. They explored the intricate chemistry behind soap formation from triglycerides and strong bases, detailing the unique structure of soap molecules with their hydrophobic tails and hydrophilic heads. The lesson also elucidated how soap effectively cleans by forming micelles that encapsulate grease, allowing it to be washed away. Finally, they touched upon the challenges posed by hard water for soap and the benefits of detergents. As a follow-up, Aashima asked for a picture of the PowerPoint slide that summarized the key learning goals: soap structure, its formation, and its cleaning action.

Aashima and Iliana reviewed organic chemistry, focusing on the properties and reactions of esters, amines, haloalkanes, alkenes, alkynes, amides, and carboxylic acids. Aashima explained concepts like polarity, hydrogen bonding, boiling points, solubility, and reactivity, including specific reactions like hydrolysis, esterification, elimination, and electrophilic addition. They plan to cover alcohols, carboxylic acids, esterification, saponification, soaps, and polymers in their next session.
