NO LINK 100 pts. In science, we have been studying the physical and chemical changes, along with the evidence of chemical reactions. Based on your understanding, write 12 - 15 sentences about the following scenario.
Oh no! Someone/something has gotten into your science kit… the box is open with the cardboard ripped up and science equipment is smashed all over the floor. The microscope is broken into 7 pieces, shattered glass is everywhere from the broken test tubes, the direction page is all crumpled up, and there is a weird greenish looking mixture that is bubbling, smoking, and burning a hole through the floor. What happened??
Consider what we have been learning in class about chemical and physical changes. Explain whether what happened to your science kit was a physical change, chemical change, or both. Use evidence from the description to defend your answer and clarify the difference between physical and chemical changes. What evidence can you look for to determine if a chemical reaction has taken place?
