AI Thread Summary
The discussion centers on whether the reaction between CuCl2 and aluminum is a chemical or physical change. Participants express confusion about the nature of the change, with some suggesting it leans towards a physical change due to CuCl2 being a solid. The importance of demonstrating one's approach to the problem before seeking help is emphasized. Ultimately, the distinction between chemical and physical changes hinges on the nature of the reactions involved. Understanding these concepts is crucial for accurately answering the teacher's question.

I just started grade 9 and one of the questions that my teacher gave us was to define whether CuCl2 and Al is a chemical or physical change.

Since we haven't done any labs with that chemcal...
I found it a bit confusing.



1. CuCl2 + Aluminum = Chemical / Physical change

2. Cucl2 + Water = Chemical / Physical change

Thanks:smile:


-------------

Found the solution
Thanks anyways ^^

You have to show you approach with each of these questions first before any of us can assist you, it's just the policy here at physicsforums.

Probably because CuCl2 is a solid?
What is the "change" that is taking place?
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
