PHYSICAL AND CHEMICAL CHANGES :)!
So, todays class we had a lab! I found it very helpful for getting my eyes used to too seeing chemical and physical changes. With the different solutions being combined, we saw various results. From, bubbles being formed, to color change and to no changes at all.
Key Words:
Difference between physcial and chemical change.
Physical Change: Reversible; no new substance is formed.
Chemical Change: Irreversible; new substance is formed.
Chemistry Experiments: Watch the video for some interesting changes.
