IV = 4,000; XXV = 25,000; The vinculum came into use in the late Republic, [50] ... Movements are often numbered using Roman numerals. In Roman numeral analysis, ...
An upper case numeral that is not followed by a symbol is understood as a major chord. The use of Roman numerals enables the rhythm section performers to play the song in any key requested by the bandleader or lead singer. The accompaniment performers translate the Roman numerals to the specific chords that would be used in a given key.
It may refer more specifically to the following manganese minerals: Birnessite, (Na,Ca) 0.5 (Mn IV,Mn III) 2 O 4 · 1.5 H 2 O; Buserite, MnO 2 ·nH 2 O; Hausmannite, Mn II Mn III 2 O 4; Manganite, Mn III O(OH) Manganosite, Mn II O; Psilomelane, Ba(Mn II)(Mn IV) 8 O 16 (OH) 4, or (Ba,H 2 O) 2 Mn 5 O 10; Pyrolusite, Mn IV O 2; Manganese may also ...
Manganese dioxide is the inorganic compound with the formula MnO 2. ... The carbonate is calcined in air to give a mixture of manganese(II) and manganese(IV) oxides.
The Roman numeral designates the formal oxidation state of an element, whereas the superscripted Indo-Arabic numerals denote the net charge. The two notations are, therefore, exchangeable for monatomic ions, but the Roman numerals cannot be applied to polyatomic ions. However, it is possible to mix the notations for the individual metal centre ...
The Roman numerals in fact show the oxidation number, but in simple ionic compounds (i.e., not metal complexes) this will always equal the ionic charge on the metal.

Manganese dioxide, which is abundant in nature, has long been used as a pigment. The cave paintings in Gargas that are 30,000 to 24,000 years old are made from the mineral form of MnO 2 pigments. [43] Manganese compounds were used by Egyptian and Roman glassmakers, either to add to, or remove, color from glass. [44]
