1,2-Dibromoethylene can be synthesized by halogenation of acetylene (C 2 H 2) with bromine (Br 2). [1] In order to prevent the formation of tetrahalogenated compounds, acetylene is used in excess, with Br 2 as the limiting reagent.
Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
The following table gives the crystalline structure of the most thermodynamically stable form(s) for elements that are solid at standard temperature and pressure.Each element is shaded by a color representing its respective Bravais lattice, except that all orthorhombic lattices are grouped together.
Forsterite. In chemistry, isomorphism has meanings both at the level of crystallography and at a molecular level. In crystallography, crystals are isomorphous if they have identical symmetry and if the atomic positions can be described with a set of parameters (unit cell dimensions and fractional coordinates) whose numerical values differ only slightly.

A lot to unpack here. Damar Hamlin called for a hold on Kelce. Then Bishop and Worthy both go up for a 50/50 ball and the refs give the catch to Worthy.
