Question

what is reaction of dihydrogen on dioxygen and halogens ​

Answer 1

Answer:

All the halogens react directly with hydrogen, forming covalent bonds and—at sufficient levels of purity—colorless gases at room temperature. Hydrogen reacts with fluorine, chlorine, bromine, and iodine, forming HF, HCl, HBr, and HI, respectively.

Group 16 elements react with oxygen to form various oxides. Some of the oxides are listed below. Group 17 elements (halogens) fluorine, chlorine, bromine, and iodine react with oxygen to form oxides. ... One of the fluorine reactions is shown below.

Answer 2

Hydrogen gas reacts with oxygen gas to form water (H2O) and reacts with halogens (X2) to produce respective hydrogen halides (HX).

• Hydrogen gas forms covalent bonds with both oxygen gas and dihalogen.
• Water produced on reaction of hydrogen gas with oxygen gas is a colourless liquid at room temperature and is a neutral compound.
• Hydrogen halides are produced on the reaction of hydrogen gas with dihalogens are colourless gases at room temperature.
• The aqueous solutions of hydrogen halides are acidic in nature with acidity increasing as one moves from fluorine to iodine.
