Asked by Callie

Johhny left a glass of milk on his bedside table for a week, and it spoiled. At the end of the week, the glass contained a yellow liquid with white chunks, and there was a terrible odor. What can be concluded?
A. The milk has undergone a physical change.
B. The mass of the milk before the change is less than the mass of the milk after the change.
C. Milk only forms ionic bonds
D. The milk has undergone a chemical change.
Is the answer A?
Answered by Brady
I agree with A.

B doesn't seem like the answer.

Both C and D also don't seem like the answer either.

So yes, I believe that A is correct for the problem.

I hope this helps! :)

P.S. I will try to keep on helping you(When I can). That, I believe may be the only way to talk on here. Same with other posts related to school it seems.

Answered by Brady
Yeah, same with me. School is "always" tough.

Answered by Brady
Yeah, it's almost the same for me. I am in 9th grade, learning like a 12th grader.
Answered by DrBob222
A is not the right answer. Look up the difference between a physical change and a chemical change.
Answered by Callie
Ok is the answer D?
Answered by Brady
DrBob222 is right, spoiling milk is a chemical reaction, not a physical reaction. Sorry! I did try though.
Answered by Brady
Yeah, I would think D.
Answered by DrBob222
D is correct.

Brady and Callie, there are other websites if you want to communicate with each other so other people don't see your conversations. One I use is Peeranswer. com It's a learning website as well, so you can help eachother out with questions and you can talk privatly. And yes D is correct.
Answered by alyssa
yes the answer is D thanks for all the help.
