When a solute is dissolved in a solvent volume of solution, which statement is true? Natural rubber consists of a monomer called what? Which can act as a propellant for rockets? Identify the unknown substances based on given chemical reactions. In the US, a bilateral meeting with China in 2024 led to discussions on drug trafficking involving which substance?
Understand the Problem
The question presents a series of chemistry-related inquiries, including the behavior of solutes in solutions, the identification of polymers, the selection of rocket propellants, and the analysis of unknown substances based on given reactions. Each question tests knowledge of chemistry concepts and compounds.
Answer
76: (B), 77: (A), 78: (C), 79: (C), 80: (D)
The correct answers are: 76: (B) may vary depending on conditions 77: (A) isoprene 78: (C) Liquid hydrogen + liquid oxygen 79: (C) Aluminium nitrate, Ammonia 80: (D) Fentanyl
Answer for screen readers
The correct answers are: 76: (B) may vary depending on conditions 77: (A) isoprene 78: (C) Liquid hydrogen + liquid oxygen 79: (C) Aluminium nitrate, Ammonia 80: (D) Fentanyl
More Information
The volume of a solution can change with conditions. Isoprene is the monomer for natural rubber. Liquid hydrogen and oxygen are common rocket propellants. Aluminium nitrate reacts with ammonia to produce a white precipitate and releases ammonia gas. Fentanyl is a concern in US-China drug trafficking discussions.
Tips
For question 76, remember the principle that volume changes based on conditions like temperature and pressure. For identifying chemical reactions, consider the potential products based on known chemical behaviors.
