  2. Magnesium oxide - Wikipedia

    en.wikipedia.org/wiki/Magnesium_oxide

    Magnesium oxide (Mg O), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide). It has an empirical formula of MgO and consists of a lattice of Mg 2+ ions and O 2− ions held together by ionic bonding .

  3. Half-reaction - Wikipedia

    en.wikipedia.org/wiki/Half-reaction

    After canceling, the equation is re-written as + + + Two ions, positive (Mg 2+) and negative (O 2−) exist on product side and they combine immediately to form a compound magnesium oxide (MgO) due to their opposite charges (electrostatic attraction). In any given oxidation-reduction reaction, there are two half reactions—oxidation half ...

  4. Magnesium compounds - Wikipedia

    en.wikipedia.org/wiki/Magnesium_compounds

    Magnesium oxide is the end product of the thermal decomposition of some magnesium compounds and is usually prepared by igniting carbonates or hydroxides. Magnesium hydroxide is a strong electrolyte, which can be obtained by the reaction of a soluble magnesium salt and sodium hydroxide.

    Magnesium: Colorless due to Magnesium Oxide layer, but burning Mg metal gives an intense white: Mn(II) Manganese(II) Yellowish green: Mo Molybdenum: Yellowish green: Na Sodium: Bright yellow; invisible through cobalt blue glass. See also Sodium-vapor lamp: Nb Niobium: Green or blue Ni Nickel: Colorless to silver-white P Phosphorus: Pale blue ...

  6. Basic oxide - Wikipedia

    en.wikipedia.org/wiki/Basic_oxide

    An oxide is a chemical compound in which one or more oxygen atoms combined with another element, such as H 2 O or CO 2.Based on their acid-base characteristics, oxides can be classified into four categories: acidic oxides, basic oxides, and amphoteric oxides and neutral oxides.

  7. Magnesium nitride - Wikipedia

    en.wikipedia.org/wiki/Magnesium_nitride

    Magnesium nitride reacts with water to produce magnesium hydroxide and ammonia gas, as do many metal nitrides.. Mg 3 N 2 (s) + 6 H 2 O(l) → 3 Mg(OH) 2 (aq) + 2 NH 3 (g). In fact, when magnesium is burned in air, some magnesium nitride is formed in addition to the principal product, magnesium oxide.

  8. Magnesium acetate - Wikipedia

    en.wikipedia.org/wiki/Magnesium_acetate

    Anhydrous magnesium acetate has the chemical formula Mg(C 2 H 3 O 2) 2 and in its hydrated form, magnesium acetate tetrahydrate, it has the chemical formula Mg(CH 3 COO) 2 • 4H 2 O. In this compound magnesium has an oxidation state of 2 +. Magnesium acetate is the magnesium salt of acetic acid. [1]

  9. Oxide - Wikipedia

    en.wikipedia.org/wiki/Oxide

    An oxide (/ ˈ ɒ k s aɪ d /) is a chemical compound containing at least one oxygen atom and one other element [1] in its chemical formula. "Oxide" itself is the dianion (anion bearing a net charge of –2) of oxygen, an O 2– ion with oxygen in the oxidation state of −2. Most of the Earth's crust consists of oxides. Even materials ...
