Discussion Overview

The discussion revolves around identifying whether specific reactions involving Drano and ammonium chloride with water represent physical or chemical changes. Participants explore the nature of exothermic reactions and their classification.

Discussion Character

  • Homework-related, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant asks whether mixing Drano with water and ammonium chloride with water results in chemical or physical changes, seeking clarification on the reasoning behind these classifications.
  • Another participant emphasizes the need for the original poster to demonstrate their understanding or reasoning before receiving assistance.
  • The original poster later indicates they have made observations that led them to a conclusion about the changes.
  • A further question is raised about whether all exothermic reactions are classified as chemical changes or if they can also be physical changes, highlighting uncertainty regarding the definitions and classifications.

Areas of Agreement / Disagreement

The discussion includes multiple viewpoints, particularly regarding the classification of exothermic reactions, and remains unresolved on whether all exothermic reactions are chemical changes.

Contextual Notes

Participants have not fully defined the criteria for distinguishing between physical and chemical changes, nor have they resolved the implications of exothermic reactions in this context.

can n e one help me with my lab? :confused: we had to mix
a)drano (a substance used to unclog drains) with water
b) ammonium chloride with water

can you tell me if these are chemical or physical changes and whyyy?? THANKZZ A BUNCH!
 
Physics news on Phys.org
Since this is homework, you need to show us some work before we can help you. What do you think?
 
ohh alriight... I actually figured it out after based on my observations
 
BUT umm..are all exothermic reactions chemical changes? or can they be physical changes aswell...since they relase heat?
