Aka Posted April 4, 2006 Share Posted April 4, 2006 Compare the results in lads 4 and 5 then provide an explanation for any differences in your observations lab 4-Cu(NO3)2+Ni= Ni(NO3)2+Cu lab 5-Ni(NO3)2+Cu = Ni(NO3)2+Cu why would there be differences?

Cap'n Refsmmat Posted April 4, 2006 Share Posted April 4, 2006 Did you actually perform these experiments or did you just get the equations? If you did the experiments yourself, then the differences would be in what happened as it reacted (I have no idea what would happen, sorry) and not the physical result.

Aka Posted April 4, 2006 Author Share Posted April 4, 2006 ya i did do the experiment but i think the question is why was there a diference if the products were the same? Link to comment Share on other sites More sharing options...
Cap'n Refsmmat Posted April 4, 2006 Share Posted April 4, 2006 You'll want to see what else comes out of the experiment besides the chemical, such as heat or light. Link to comment Share on other sites More sharing options...

Cap'n Refsmmat Posted April 4, 2006 Share Posted April 4, 2006 So then compare those and try to explain why you got that. Link to comment Share on other sites More sharing options...
