Hydrogen and fluorine combine to yield hydrogen fluoride, in which discrete molecules form clusters by hydrogen bonding, resembling water more than hydrogen chloride. [ 126 ] [ 127 ] [ 128 ] It boils at a much higher temperature than heavier hydrogen halides and unlike them is miscible with water. [ 129 ]

The bond energy is significantly weaker than those of Cl 2 or Br 2 molecules and similar to the easily cleaved oxygen–oxygen bonds of peroxides or nitrogen–nitrogen bonds of hydrazines. [8] The covalent radius of fluorine of about 71 picometers found in F 2 molecules is significantly larger than that in other compounds because of this weak ...
It is used as a food coloring, [11] printing ink, [12] biological stain, [13] dental plaque disclosing agent, [14] radiopaque medium, [13] sensitizer for orthochromatic photographic films, and visible light photoredox catalyst. [15] Erythrosine is commonly used in sweets, such as some candies, ice pops and cherries, and in cake-decorating gels ...
The bonding within dioxygen difluoride has been the subject of considerable speculation, particularly because of the very short O−O distance and the long O−F distances. The O−O bond length is within 2 pm of the 120.7 pm distance for the O=O double bond in the dioxygen molecule, O 2.
Brilliant blue FCF (Blue 1) is a synthetic organic compound used primarily as a blue colorant for processed foods, medications, dietary supplements, and cosmetics. [1] It is classified as a triarylmethane dye and is known under various names, such as FD&C Blue No. 1 or acid blue 9.
The color of the water balloons doesn’t matter, but the color of the food dye that you drip inside does. Grab whatever color dye you want your marbles to be, and add a few drops to the inside of ...
Amaranth, FD&C Red No. 2, E123, C.I. Food Red 9, Acid Red 27, Azorubin S, or C.I. 16185 is a modified red azo dye used as a food dye and to color cosmetics. The name was taken from amaranth grain , a plant distinguished by its red color and edible protein-rich seeds.
