There is only one structure feasible for a tetrahedral molecule with such a formula, under the supposition that A is in the center of the tetrahedredon. In this case X and Y are in the vertices of the tetrahedron.
If you draw several figures changing the position of the X's and the Y around the center (A), you will see that all are equivalent.
This is the case of the product CH3Cl, named chloromethane, which, for the same reason given above, does not have isomers.
It is proven to help build healthy muscles, joints, bones etc. It also has a good effect on your academic performance, as it increases the oxygen flow to the brain.
I’m pretty sure that’s a codon
<span>Explanation: Phosphorous cycles through several components of the biosphere, hydrosphere, and geosphere. However, it generally does not circulate through the atmosphere, unlike other biogeochemical cycles, like for example carbon or nitrogen.</span>
Sometimes, I think it's just how it reacts to the air but if it was crazy bubbles I'd be skeptical I'm a pretty paranoid person though...
