🚨 CONTENT COVERED IN CLASS 🚨 ✓ Chemistry review for the first qualifying exam of the UERJ 2027 state entrance exam UERJ 2026 - Observe the structural formula of fentanyl, a synthetic opioid used as an anesthetic, whose indiscriminate consumption generates serious consequences: UERJ 2026 - The process of artificial photosynthesis, among other objectives, aims at the production of clean energy. This process begins with the decomposition reaction of water, forming hydrogen, which will react with CO2 from the atmosphere, as represented in the following equation: UERJ 2026 - Arsenic(III) oxide has the following molecular formula: UERJ 2025 - To attract individuals of the opposite sex, female houseflies exhale a pheromone, whose molecule is represented by the following spatial structural formula. UERJ 2024 - Observe the chemical equation that represents the hydrolysis of calcium carbide. UERJ 2024 - At nightfall, the retinal cells involved in the perception of light trigger signals that stimulate the pineal gland to produce and secrete melatonin, a hormone responsible for preparing the body for rest. Because it is composed of a hydrophilic and a hydrophobic portion, melatonin easily penetrates the plasma membrane of different types of cells. This ease of penetration of melatonin is due to the composition of the plasma membrane, which contains molecules of the following types: UERJ 2023 - The chemical reaction between methane and molecular chlorine produces hydrochloric acid and dichloromethane, the latter compound being used as a solvent in industrial processes. The bond energy values ​​involved in the reaction are presented in the following table. ✏️ Spreadsheet with ALL the channel's lessons - https://bit.ly/4cQRqwP 🔔 SUBSCRIBE TO THE CHANNEL - https://bit.ly/3zY1x21 👍 Did you like the video?
