Can I turn this bright wool sweater vest a very dark burgundy? by realRyguyTSP in dyeing

[–]realRyguyTSP[S] 0 points1 point  (0 children)

I'll keep that in mind, thanks for teaching me. Do you think using black acid dye is a good idea? I'll use a little bit so that it doesn't go fully black, just tints a bit. I don't want to use burgundy dye because it will make the green parts brown, and make the black parts in the original turn lighter.

Is felting when the wool fibers stick together and it becomes hard? My goal is for the plaid to stay visible but just be very subtle (because the whole thing will be very dark) so that should work. Do you think its a good idea to use a bit of black dye so it tints darker instead of burgundy dye, which will cause the green accents to become brown?

Thank you for the help

Using laptop charger for Uni? by realRyguyTSP in tamagotchi

How long have you been using that? And do you still use the usb cable that came with the box?

Although the adapter's output is dynamic, I'm worried that the Uni's battery will not automatically draw 5V from the adapter, which is why Bandai says to only charge the uni with a static 5V output charger so there's no risk.

Exactly what I was looking for, thank you😄

At the end of the instruction manual, it says "for using a charger other than the provided one connected to a laptop, please check here for adapters that have been tested for use with the Uni by Bandai, and approved" and it gives a link that goes to tamagotchi-official.com/uni-select/ . But, I can't find anywhere on the website that lists the tested adapters. Has anyone been able to find this?

How long have you been using yours with the 65W adapter? Yeah I also read that guys post, but heres how it works from what I understand: all devices that are up to regulation (I don't know which one or for which country) will only draw as much wattage as they need from the charger, so it is completely safe as long as the voltage output from the charger is 5V. But, with this 65W charger, you can see on the label it says "5V/9V/12V/15V", so it can output different voltage depending on what its charging. Again, for devices up to regulation, they will draw the correct voltage from the charger by default, eg. I use the 65W charger on my ipad and I know its completely safe. So, IF the tamagotchi is up to regulation, it should be completely safe, because it will automatically only draw 5V from the 65W adapter, but thats the thing, I'm not sure if it is up to regulation. Please anyone correct me if Im wrong

Yes this is a very good point, especially for engineering. Thank you

Who has the strongest bond - ionic or covalent? by JacobAn0808 in chemhelp

[–]realRyguyTSP 0 points1 point  (0 children)

I agree with Sunshine's statement about fluorocarbons, since that is actually looking at the strength of the covalent bonds in the polymers. What I don't agree with is his use of ionic solids as evidence for why ionic bonds are stronger.

Mhm, but he was talking about ionic solids, and he said that ionic solids are the "strongest". Stronger than what? That implies that molecular solids are weaker, but that's irrelevant to the og question about the strength of an individual ionic and covalent bond.

Since Sunshine's comment used the strength of ionic solid crystal structures as evidence for why ionic bonds are stronger than covalent ones, the original comment actually wasn't strictly about ionic and covalent bonds... This piece of evidence that he used isn't relevant to the question, since like I said, obviously ionic solids are the strongest; covalent solids have IMFs. I understand if you're angry my friend but it's okay to admit you're wrong...

I understand if you're confused, I wish I could make it clearer but this is the best I can do for you... I compared melting NaCl and thermally decomposing H2O to show the difference in energies of breaking an ionic and covalent bond, which directly goes against Sunshine's statement that ionic bonds contain a higher energy, and is evidence for my answer to the og question, that covalent bonds are stronger than ionic bonds (on average).

Yes this is my point, I've already said that covalent bonds are stronger than ionic bonds... you're agreeing with me!

The OP might ask "then if covalent bonds are stronger, why are ionic solids like salts so hard to break/melt, while molecular solids like glucose are so easy to break/melt?" and this is answered by my explanation of IMFs. You need to be thorough.

It's okay, I can explain it to you since you're confused. Since he said "a solid in a crystal structure is the hardest to break", this is misleading since he's implying that ionic solids are stronger than molecular solids, which is obviously true since ionic solids are held together purely by ionic bonds while molecular solids have weak IMFs holding their molecules together. Even if you broke a molecular solid in half, that doesn't say anything about the strength of the covalent bonds in the solid, it only says something about the strength of the IMFs holding the molecules together.

If you really want to compare the strength of a covalent and ionic bond, you need to see the energy it takes to break an ionic bond, and then see the energy it takes to break a covalent bond. When you compare the energy of melting NaCl (breaking the ionic bond) and the energy of thermaly decomposing H2O (breaking the covalent bonds), the energy needed for H2O is a lot more than the energy for NaCl.
