It reacts with almost all substances (even water burns in fluorine, products not a bright flame). It reacts with hydrogen to form hydrogen fluoride. When hydrogen fluoride is dissolved in water, it forms hydrofluoric acid. Fluorine is very poisonous.]]> 2018-09-23 13:17:07 UTC https://padlet.com/contrjer000/l2g6eja9l2r8/wish/284739431 Compound with fluorine contrjer000 https://padlet.com/contrjer000/l2g6eja9l2r8/wish/284742981 Tin(IV) fluoride is a chemical compound of tin and fluorine with the chemical formula SnF and it is a colorless solid used as an ingredient in toothpastes as an alternative to sodium fluoride.]]> 2018-09-23 13:46:13 UTC https://padlet.com/contrjer000/l2g6eja9l2r8/wish/284742981 contrjer000 https://padlet.com/contrjer000/l2g6eja9l2r8/wish/284743517 Most crests toothpastes have Tin(IV) fluorine in them]]> 2018-09-23 13:49:50 UTC https://padlet.com/contrjer000/l2g6eja9l2r8/wish/284743517 Mixtures with fluorine contrjer000 https://padlet.com/contrjer000/l2g6eja9l2r8/wish/284745420 Hydrofluoric acid can dissolve glass and is used to etch the glass in light bulbs ]]> 2018-09-23 14:00:43 UTC https://padlet.com/contrjer000/l2g6eja9l2r8/wish/284745420 contrjer000 https://padlet.com/contrjer000/l2g6eja9l2r8/wish/284746328 Lightbulb in hydrofluoric acid]]> 2018-09-23 14:08:05 UTC https://padlet.com/contrjer000/l2g6eja9l2r8/wish/284746328
