Complex compounds[edit]
Hi everyone, today, I will ask question about color of two complexes:
- CoBr2(urea)10 (1), and
- FeCl3(thiourea)6 (2).
I don't think that (2) will have light pink color, compound (1) is ... (I don't know), :(. If you can, please tell me what is exactly color of these compounds. Thanks for very much (Sorry if you don't understand, because my English is not good). --Ccv2020 (talk) 10:36, 28 May 2020 (UTC)

- As when you asked about these many times before, is there some specific reason, purpose, or goal to your questions on the colors of these many transition metal complexes (many of which have not even existed)? It would very much help us answer and support you if we had an idea what you were trying to do. You may have a great goal in mind, we just need a little more from you in orrder to help. --OuroborosCobra (talk)
@OuroborosCobra: Now I have color of complex (1): [2]
- That's not an answer to anything I asked. --OuroborosCobra (talk) 17:19, 31 May 2020 (UTC)
Mechanics[edit]
Why is the information surrounding automobiles and automobile repairs so poor everything is theory nothing is real life the information on automobiles in Wikipedia is very much on the weak side or anything mechanical for that matter you need to step it up — Preceding unsigned comment added by 24.192.193.98 (talk) 13:18, 28 May 2020 (UTC)
- Everything here was contributed by volunteers. If it doesn’t meet your lofty standards, perhaps you could volunteer too. Brianjd (talk) 13:27, 28 May 2020 (UTC)
- Can you give us a specific example? ←Baseball Bugs What's up, Doc? carrots→ 15:25, 28 May 2020 (UTC)
- Note that Wikipedia is an encyclopedia, and doesn't offer "how-to" instructions (see:WP:NOTHOWTO). Wikihow (unaffiliated) does. 107.15.157.44 (talk) 21:40, 28 May 2020 (UTC)
- This is something I've been thinking about myself for about four to five years now, that Wikipedia is often weak on some "practical" technology of massive economic importance, such as techniques in the construction, logistics, manufacturing and food industries, whereas our coverage of more academic disciplines taught in traditional universities, such as biomedical science, is much better. We didn't have an English-language article on the N95 mask, currently the world's hottest commodity, until three months ago (there was one in Japanese). I think there's a very clear divide, that people with a "traditional university" education are more likely to end up editing Wikipedia than people with a more "community college" education-which is a real problem when topics of vast practical and business importance get undercovered. (And it's something far less discussed than our well-known problem with encouraging female contributors.) Off and on I've particularly tried to add pictures on industrial techniques from Flickr whenever I can find them, even of really mundane things. I'm not an automobile person, but if you want help with something please ask and I'll try my best to help you. Blythwood (talk) 23:12, 30 May 2020 (UTC)
- Slightly off-topic: So where were all the Wikipedia editors during that other respiratory pandemic that occurred during the Wikipedia era? Turns out the article says a lot about masks but nothing about what type of masks anyone is talking about. Even Influenza prevention has nothing to say on this subject. Coronavirus disease 2019 has plenty to say though. Brianjd (talk) 10:00, 31 May 2020 (UTC)
