Question

can someone double checks these for me please

Answer 1

For the states of matter question, I do not think "solids" is the answer you want. While it's technically true that all particles are constantly vibrating or moving in some way, I think the question is hinting at another state of mater, where the particles are in contact with each other but still able to move around past each other. In a solid, the position of the particles are more-or-less fixed relative to one another.

Organic chemistry would study organic compounds. I think this means compounds containing Carbon, so that could be a hint towards the answer you want for that question.

Those are the only issues I could find with your answers. You may want to get a second opinion, considering that I am not a real scientist :)

Answer 2

thank you

Answer 3

No problem!

For what it's worth, I'm pretty sure you got the other ones that I didn't mention correct. Except for the question about "physical chemistry", I'm not really sure what the answer for that one would be, so I can't really say.

Glad I could help :)
