Endothermic Decomposition Experiment

Click For Summary

Discussion Overview

The discussion revolves around an experimental scenario involving the reaction of a metal with fluorine gas in a combustion chamber, focusing on whether the reaction can be classified as endothermic decomposition. Participants explore the implications of temperature changes and the nature of the reactants and products.

Discussion Character

  • Exploratory, Homework-related, Conceptual clarification

Main Points Raised

  • One participant suggests that the reaction could be classified as endothermic decomposition based on the experimental observations.
  • Another participant questions whether the increase in temperature during the reaction indicates that it is endothermic, prompting a discussion about the nature of endothermic versus exothermic reactions.
  • A different participant raises the idea that since two reactants entered the chamber and one product was formed, this could indicate a decomposition reaction.
  • One participant expresses uncertainty and requests clarification on what specific substances are decomposing in the reaction.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the classification of the reaction, with multiple competing views regarding whether it is endothermic and whether it qualifies as a decomposition reaction.

Contextual Notes

Participants have not provided specific details about the substances involved, and there are unresolved questions regarding the definitions of endothermic and decomposition reactions in this context.

I am doing an assignment and I'm not sure if the answer is endothermic decomposition someone please help me!
During an experiment, a metal and an excess of fluorine gas were placed into a combustion chamber at a temperature of 1800°C. The temperature in the sealed chamber continued to rise to 2100°C. After the reaction stopped, a brittle white substance, which dissolved in water, was extracted from the chamber. From this evidence one could conclude that this reaction can be classified as

I'm no chem expert (by any means), but if the sealed chamber's temperature rose during the reaction, would the RX be endothermic? What are the other options...?
 
And if two things went in and one thing came out ... would the rxn be a decomposition?

This is not an attempt at a solution. This is just a wild guess.

At the very least you should tell us what you think is decomposing into what.
