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?

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.

ya i did do the experiment but i think the question is why was there a diference if the products were the same?

You'll want to see what else comes out of the experiment besides the chemical, such as heat or light.

#4

 

Nickel

Became less smooth and less shiny

Copper Nitrate

No noticeable difference.

 

#5

 

Nickel Nitrate

White liquid floats

Copper

Increases shine

Retains other characteristics

 

thoes were the results

So then compare those and try to explain why you got that.
