    Neon Point
AI Thread Summary
Neon-22 has a higher density than neon-20 due to its greater mass, as it contains more neutrons. The discussion suggests that neon-22 may also have a higher boiling point because its increased mass could lead to greater resistance to changes in state, requiring more heat to overcome this resistance. The participants express uncertainty but lean towards neon-22 being the correct answer for both density and boiling point. Overall, the relationship between mass and physical properties like density and boiling point is emphasized. Understanding these concepts is crucial for accurately comparing isotopes.

Homework Statement



Pure samples of neon have different densitys and boiling points

b)which has highest density: neon 20 or 22



attempt at answer

I believe that the highest density would be neon 22, infact I am almost sure (lmao if i am wrong :P) I am not so sure about highest boiling point however neon 22 also seems like the logical answer to this as there is more neutrons however i am confused because i am sure i should use both of them :O

please can someone give an answer and explain it :D. This would be greatly appreciated
 
Physics news on Phys.org
Density is simply mass per unit volume, e.g. kg/m3 or gm/cm3. The nucleus of Ne-22 is approximately 2 amu heavier than the nucleus of Ne-20.

A more massive object offers more resistance to forces/acceleration. What implication might that have for a boiling point?
 
So if that's the case then if more resistance is put up by the neon 22 then it would have the highest boiling point also as it would take more heat for the resistance to be overcome :D. Please feel free to correct if I'm wrong :P

Thankyou very much mate :D

apreciate it, Tonto :D

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
