Resolução Química Santa Marcelina 2026: Questão 06 (Banca Vunesp) #vunesp #quimicavunesp

In this video, I solve Question 6 from the Santa Marcelina 2026 entrance exam (second semester admission), prepared by the Vunesp exam board. This is a classic Chemistry question that involves fundamental topics for your success in entrance exams: Stoichiometry, Balancing Equations, and Redox Reactions. Understand the step-by-step process to calculate the oxidation number (NOX) of chromium, balance the "breathalyzer" equation, and identify the aldehyde produced. A great opportunity to practice for upcoming Vunesp exams! 📌 Timestamps to facilitate your studies: [03:38] Calculation of the oxidation number (NOX) of chromium. [06:16] Balancing the chemical equation. [09:55] Stoichiometry solution (Water vs. dichromate mole ratio). [10:39] Structural formula of the aldehyde produced. [11:56] Explanation of the relationship between color intensity and ethanol concentration. ✅ Subscribe to the channel to follow the complete solution of the Santa Marcelina exam and other Vunesp exams.
