  2. Manganese(II) carbonate - Wikipedia

    en.wikipedia.org/wiki/Manganese(II)_carbonate

    Manganese carbonate is a compound with the chemical formula Mn CO 3. Manganese carbonate occurs naturally as the mineral rhodochrosite but it is typically produced industrially. It is a pale pink, water-insoluble solid. Approximately 20,000 metric tonnes were produced in 2005. [3]

  3. Symbolab - Wikipedia

    en.wikipedia.org/wiki/Symbolab

    Symbolab is an answer engine [1] that provides step-by-step solutions to mathematical problems in a range of subjects. [2] It was originally developed by Israeli start-up company EqsQuest Ltd., under whom it was released for public use in 2011.

  4. List of equations in classical mechanics - Wikipedia

    en.wikipedia.org/wiki/List_of_equations_in...

    Classical mechanics utilises many equations—as well as other mathematical concepts—which relate various physical quantities to one another. These include differential equations, manifolds, Lie groups, and ergodic theory. [4] This article gives a summary of the most important of these.

  5. Ankerite - Wikipedia

    en.wikipedia.org/wiki/Ankerite

    Ankerite is a calcium, iron, magnesium, manganese carbonate mineral of the group of rhombohedral carbonates with the chemical formula Ca(Fe,Mg,Mn)(CO 3) 2.In composition it is closely related to dolomite, but differs from this in having magnesium replaced by varying amounts of iron(II) and manganese.

  6. Rhodochrosite - Wikipedia

    en.wikipedia.org/wiki/Rhodochrosite

    Rhodochrosite is a manganese carbonate mineral with chemical composition MnCO 3. In its pure form (rare), it is typically a rose-red colour, [ 5 ] but it can also be shades of pink to pale brown. It streaks white, [ 6 ] and its Mohs hardness varies between 3.5 and 4.5.

  7. Lists of physics equations - Wikipedia

    en.wikipedia.org/wiki/Lists_of_physics_equations

    In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field. Physics is derived of formulae only.

  8. Kutnohorite - Wikipedia

    en.wikipedia.org/wiki/Kutnohorite

    Kutnohorite is a rare calcium manganese carbonate mineral with magnesium and iron that is a member of the dolomite group. It forms a series with dolomite, and with ankerite.The end member formula is CaMn 2+ (CO 3) 2, [6] but Mg 2+ and Fe 2+ commonly substitute for Mn 2+, with the manganese content varying from 38% to 84%, [2] so the formula Ca(Mn 2+,Mg,Fe 2+)(CO 3) 2 better represents the species.

  9. Manganoan calcite - Wikipedia

    en.wikipedia.org/wiki/Manganoan_Calcite

    Manganocalcite. Manganoan calcite or manganocalcite is a variety of calcite rich in manganese, which gives the mineral a pink color. [1] Its chemical formula is (Ca,Mn)CO 3.It was first reported from the Banská Štiavnica Mining District, Slovak Republic, [1] but is widely distributed around the world, notably in the Cave of Swords at Naica, Chihuahua, Mexico as well as in Bulgaria.
