Oxidation numbers of nitrogen

Show that the oxidation number of nitrogen is + 5 in each of the two species N03 and N2Ot. [Pg.219]

The blue gas dinitrogen trioxide, N203 (Fig. 15.6, 1), in which the oxidation number of nitrogen is +3, is the anhydride of nitrous acid, HN02, and forms that acid when it dissolves in water ... [Pg.749]

Nitrogen forms oxides in each of its integer oxidation states front +1 to +5 the properties of the oxides and oxoacids are related to the oxidation number of nitrogen in the compound. [Pg.750]

The oxidation number of nitrogen increases, so nitrogen dioxide is oxidized to nitrate ions. [Pg.490]

The oxidation number of nitrogen increases from -3 to +4, an increase of 7. The oxidation number of oxygen decreases from 0 to -2, a decrease of 2. The least common multiple of 7 and 2 is 14. In this case, two nitrogen atoms must react for every seven oxygen atoms so that the total increase and decrease in oxidation numbers both equal 14. [Pg.495]

Problem 34 What is the oxidation number of nitrogen in magnesium nitride (Mg3N2) and in nitric acid (HNO3) ... [Pg.113]

The tetrafluoroammonium cation (NF/) has high electronegativity (the oxidation number of nitrogen is + 5) and high kinetic stability (NF4+ is isoelectronic with CF4).15 -17 It has been shown that in anhydrous hydrogen fluoride, benzene and its derivatives are fluorinated by tetrafluoroammonium tetrafluoroborate with substitution of hydrogen by fluorine.15-17...

Example 7.4 Determine the oxidation number of nitrogen in each species of the sequence 7.7. [Pg.155]

Calculate the oxidation number of nitrogen in (a) hydrazoic acid, HN3, (b) ammonia, NH3, and (c) hydrazine, N2H4. [Pg.448]

The oxidation number of copper increases from 0 to +2 as it is oxidized in the reaction. The oxidation number of nitrogen decreases from +5 to +4 as it is reduced in the formation of NO2. The oxidation numbers of hydrogen and oxygen do not change. Note that the nitrogen atoms remain unchanged in the nitrate ion (N03 ), which appears on both sides of the equation. It is neither oxidized nor reduced. [Pg.645]

Nitrogen dioxide is a choking, poisonous, brown gas that contributes to the color and odor of smog. The oxidation number of nitrogen in NO2 is-1-4. NO2, like NO, is paramagnetic. It disproportionates in water to form nitric acid and nitrogen oxide ... [Pg.191]

Nitrous acid can be produced in aqueous solution by mixing its anhydride, dinitrogen trioxide, with water. The oxidation number of nitrogen in HNO2 is -i-3. N20s(g) -1- H20(l) 2HN02(aq)... [Pg.191]

Nitric acid, a widely used industrial and laboratory acid, is produced by the three-step Ostwald process. The oxidation number of nitrogen in HNO3 is +5. [Pg.192]

The N2 molecule contains a triple bond and is very stable with respect to dissociation into atomic species. However, nitrogen forms a large number of compounds with hydrogen and oxygen in which the oxidation number of nitrogen varies from -3 to +5 (Table 21.2). Most nitrogen compounds are covalent however, when heated with cer-... [Pg.842]

This is a disproportionation reaction (see p. 130) in which the oxidation number of nitrogen changes from -1-4 (in NO2) to -1-3 (in HNO2) and -1-5 (in HNO3). Note that this reaction is quite different from that between CO2 and H2O, in which only one acid (carbonic acid) is formed. [Pg.845]

Determine the oxidation numbers of nitrogen in the following species (a) N2O4, (b) NH3,... [Pg.139]

The oxidation number of copper increases from 0 to +2. The oxidation number of nitrogen decreases from +5 to +4. [Pg.690]

The oxidation number of nitrogen in nitrous acid is +3. Since this value is between the extremes of a +5 and -3 for nitrogen, nitrous acid can be either oxidized or reduced. Nitrous acid can oxidize HI to I2 (in other words HI acts as a reducing agent). [Pg.611]

A strong oxidizing agent can oxidize nitrous acid to nitric acid (oxidation number of nitrogen +5). [Pg.611]

The oxidation number of an atom of a free element is zero. For example the oxidation number of nitrogen in N2 or calcium in Ca is 0. [Pg.103]
