Ok, so I did a lab today that involves me and a partner determining whether certain elements and compounds are soluble, conductive, conductive in water, or if they react with certain chemicals. I got all that done, now I'm on the analysis, which is due tomorrow morning. Problem is, the teacher didn't tell us the names of any of the materials we worked with in an effort to make us think, but I have no idea how to distinguish an element from a compound. Smart people, help?
I'm pretty sure you were smart enough to look up the difference but that probaly didn't help so can you show a pic of your work.
Compound is a mixture of elements combined such as h20 is compound while h(hydrogen) is just an element
The thing is, I can't find the difference. I can't really show my work, though, since there is no work. Basically, there's this. "Elements are composed of one substance that cannot be subdivided." Simple enough. "Compounds are composed of more than one elements." Fine. The tests made were... appearance, conductivity, water solubility (if it's a powder or crystal), whether or not it's conductive where dissolved in water, and it's reaction with HCe or CuCl2. Established.
I'm in Bio AP and I know this... an element is the smallest form of matter that can not be broken ito smaller materials, it's the purest form.
Why do people keep telling me the same thing, this is Chem 2, not 6th grade science. We have to take this class to get into AP Bio (which I don't plan on taking) You should know this!!!
I took AP bio and chem 2 years ago...after the AP test I forgot everything EVERYTHING. should've asked then now I'm stuck with physics and multivariate calc
Ok, asked a friend in my class (should've done this in the first place ) Anything that reacts is a compound (cause they can be broken down, and if they react, than what else can they be doing?) Anything that's soluble and conductive when dissolved is a compound (ionic compound). Anything that dissolved but isn't conductive when in water is a compound (polar covalent compound). Anything that doesn't dissolve and isn't conductive when dissolved is a compound (non-polar covalent compound). Should've been able to figure this out on my own. Ah, well. Thx, smart people!
I bet if you stayed off this website for just one day...just one, you would learn so much more & you wouldn't be here trying to find out the difference between the two. I challange you to not post for 24hrs (that's hours) & learn something. Dont you have a book? Or google....you know how to search your bum off in this site but you can't do a google search for homework due in the morning & you come here to post spam threads....weak move Kam.
oh I didn't quite understand what you were asking, they are also refered to as bonds and polar covalent bonds are the strongest bonds(fact you need to know).
"Don't even be tryin tah go there with me girlfriend, I'm a crazy mofo, I once had to pop a cap in a cops ass for not givin me my props in oaktown" ....."no? I heard that somewhere"
