Suppose A is more reactive than B, as in, A reacts with a bunch of other substances faster than B does. Then can there be cases where B reacts with something better than A does? Note that, I imagine to make this question useful, we must make A and B in the same category of something. Like, A and B should both be metals. So if A reacts with 10 different acids better than B does, can B react with an acid that A doesn't? Or B reacts with a base that A doesn't? Can it be such that B reacts with gases better than A does?
Since this is such a specific question, I'll throw in another 1. Our article on chemiluminescence says the 1st accidental discovery was in 1877. But the source is in German. Just wondering if anyone compiles a list of discoveries of chemiluminescence in order, I'm curious to know what the 1st discovery is by theory and not by accident. I'm also wondering if anyone discoveries chemiluminescence in say, the past 20 years, by accident, or and by theory still. 67.165.185.178 ( talk) 14:51, 6 November 2021 (UTC).
See the recent edit to crop (anatomy) here. The anon rightly points out in his/her edit summary that the article states that ducks and geese don't have crops, but the article is illustrated with an image and a video showing a duck and a goose, apparently with a bulging crop. I have found some websites (e.g. this) that say that ducks and geese don't have crops too. So I have no idea. Anyone able to help? I only really know about parrots to any great extent. -- Iloveparrots ( talk) 20:26, 6 November 2021 (UTC)
I found lots of links saying they do, including dissected ducks. Greglocock ( talk) 22:49, 6 November 2021 (UTC)
