The compound can also be created in the gas phase by reacting nitrogen dioxide NO 2 or N 2 O 4 with ozone: [13] 2 NO 2 + O 3 → N 2 O 5 + O 2. However, the product catalyzes the rapid decomposition of ozone: [13] 2 O 3 + N 2 O 5 → 3 O 2 + N 2 O 5. Dinitrogen pentoxide is also formed when a mixture of oxygen and nitrogen is passed through an ...
Pyrrhotite, an example of a non-stoichiometric inorganic compound, with formula Fe 1−x S (x = 0 to 0.2). The monosulfides of the transition metals are often nonstoichiometric. Best known perhaps is nominally iron(II) sulfide (the mineral pyrrhotite) with a composition Fe 1−x S (x = 0 to 0.2).
Liquid phase of MON contains no nitric oxide. [2] N 2 O 4 ⇌ 2NO 2. NO 2 + NO ⇌ N 2 O 3. A broad range of compositions is available, and can be denoted as MONi, where i represents the percentage of nitric oxide in the mixture (e.g. MON3 contains 3% nitric oxide, MON25 25% nitric oxide). An upper limit is MON40 (40% by weight).
The following equation is an example, where M represents the given metal: MCO 3 → MO + CO 2. A specific example is that involving calcium carbonate: CaCO 3 → CaO + CO 2. Metal chlorates also decompose when heated. In this type of decomposition reaction, a metal chloride and oxygen gas are the products. Here, again, M represents the metal:
Gas blending is the process of mixing gases for a specific purpose where the composition of the resulting mixture is defined, and therefore, controlled. A wide range of applications include scientific and industrial processes, food production and storage and breathing gases.
Metals react with acids to form salts and hydrogen gas. Liberation of hydrogen gas when zinc reacts with hydrochloric acid. + () + [2] [3] However, less reactive metals cannot displace the hydrogen from acids. [3] (They may react with oxidizing acids though.)
Dinitrogen tetroxide can also be produced by heating metal nitrates. [11] The oxidation of copper by nitric acid is a complex reaction forming various nitrogen oxides of varying stability which depends on the concentration of the nitric acid, presence of oxygen, and other factors.
Examples are gases carbon monoxide (CO), nitric oxide (NO), and hydrogen chloride (HCl). Many 1:1 binary compounds are not normally considered diatomic because they are polymeric at room temperature, but they form diatomic molecules when evaporated, for example gaseous MgO, SiO, and many others.
