Answer 2

This is too much, what is the question?

Answer 3

Just an over all idea of what to study

Answer 4

Chemical change- any change that results in a new formation of a substance.
For ex. burning paper.

Physical change- rearranging molecules but doesn't affect its internal structure.
For ex. splashing water in your hair. Or, dicing an apple. you're changing it but it's still the same thing.

Answer 5

Thanks you!

Answer 6

Chemical change- breaking down or creating new chemical bonds between atoms like
iron rusting or eggs cooking

Answer 7

Alright, anything for the parts of actual yield and percent yield?

Answer 8

i haven't learned that stuff yet, sorry...

Answer 9

Alright, Thanks anyways
