It is a positively charged molecular ion with the chemical formula NH + 4 or [NH 4] +. It is formed by the addition of a proton (a hydrogen nucleus) to ammonia ( NH 3 ). Ammonium is also a general name for positively charged (protonated) substituted amines and quaternary ammonium cations ( [NR 4 ] + ), where one or more hydrogen atoms are ...

When heated in a sealed tube at 500 °C, It decomposes to rhenium dioxide: [1] 2NH 4 ReO 4 → 2ReO 2 + N 2 + 4 H 2 O. The ammonium ion can be displaced with some concentrated nitrates e.g. potassium nitrate,, silver nitrate, etc.: [2] NH 4 ReO 4 + KNO 3 → KReO 4 ↓ + NH 4 NO 3. It can be reduced to nonahydridorhenate with sodium in ethanol: [2]
Ammonium iodide is the inorganic compound with the formula NH 4 I. A white solid. It is an ionic compound, although impure samples appear yellow. This salt consists of ammonium cation and an iodide anion. [1] It can be prepared by the action of hydroiodic acid on ammonia. It is easily soluble in water, from which it crystallizes in cubes.
Formula One, abbreviated to F1, is the highest class of open-wheeled auto racing defined by the Fédération Internationale de l'Automobile (FIA), motorsport's world governing body. [1] The "formula" in the name refers to a set of rules to which all participants and cars must conform. [2]
Juan Manuel Fangio (Spanish: [ˈxwam maˈnwel ˈfaŋxjo], Italian:; 24 June 1911 – 17 July 1995) was an Argentine racing driver, who competed in Formula One from 1950 to 1958.
The correct formula notation for ammonium paratungstate is therefore (NH 4) 10 [H 2 W 12 O 42]·4H 2 O. The [H 2 W 12 O 42 ] 10− ion is known as the paratungstate B ion, as opposed to the paratungstate A ion, that has the formula [W 7 O 24 ] 6− , similar to the paramolybdate ion.
Because ammonium iodate consists of the reducing ammonium ion and the oxidizing iodate ion, it already starts to decompose at 150 °C into nitrogen, oxygen, iodine and water. NH 4 IO 3 → 1 / 2 N 2 + 1 / 2 O 2 + 1 / 2 I 2 + 2H 2 O
