H2, N2, and NH3 : Comparing Boiling Points
Вставка
- Опубліковано 9 чер 2024
- NH₃ has the highest boiling point because it experiences stronger hydrogen bonding compared to the weaker London dispersion forces in H₂ and N₂. Comparing N2 and H2, the greater molar mass of N2 means it will have a higher boiling point than H2.
Here are the boiling points for each substance:
H2 boils at -252.8C
N2 boils at -195.8C
NH3 boils at -33.1C

Sir, we all love you ❤️
Always proud to be a student of you. You never fail to clear the doubts of your students
Thank you for the kind words!
Video. To help the AP chemistry students
Mr B do you have any videos on presssure conversion?
You might look at my website under Gas Laws (breslyn.org/) for some info there. I also have some specific videos for atm and mmHg on my channel. If you search youtube for convert mmHg or convert atm they should come up. Hope that helps!
Question: why during reaction of MnO2 and HCl, MnO2 get converted into MnCl2 and not MnCl4 ?
I'd guess that MnO4 isn't as stable as MnO2. Mn2+ has half filled 3d orbitals which would be more stable than 4+
Teach ap chemistry I like 1 though 9 unit
SIR CAN YOU HELP ME WATS IUPAC Name
Please respond to my prior comments about AP if you could teach AP chemistry just like one unit Review to 9 unit review
Tell your mom thanks! Unfortunately Thermochem is the one area I've not created much content. It's on the list but it'll be a while. Any other topics you need help with?
You can also take a look at my website, www.Breslyn.org for other topics though, lots of free guides that link to my videos there.
Because I might just be taking AP next year and that’s why I’m asking but thanks for responding to it at least picture telling me that there might be stuff on the website so I’ll look at that at my dad’s
No problem and all the best if you decide to take AP chem next year.
OK all I’m just asking is just gonna be like a 15 minute video for each unit and that’s it for a P kids I think you can do like Thermo chemistry I haven’t learned and since our teacher was on leave of absence because he was having a child he teaches AP but yeah just like can you at least Try to start it that would be fun if you could at least try like started it shouldn’t take you that long but at least try to do a video for thermochemistry I like started maybe in July or August for like a 15 minute video if that’s fine if you don’t want to do it I’m just asking for it thank you for the feedback was very nice of you should be my last comment so yeah
This is the one that the person wants you to respond to do a 15 minute video
Please respond to this my mom Recommended me to you
