What is the formula for manganese(iv) silicate?
The chemical formula for manganese(IV) silicate is MnSiO3. In this compound, manganese has an oxidation state of +4, indicated by the Roman numeral IV in parentheses. Silicate is a polyatomic ion with a charge of -2, so one manganese ion combines with one silicate ion to form a neutral compound.
In bowens reaction series how do the tetrahedra in feldspar differ from those of silicates?
The simple answer is... Feldspar has a much higher complex and stable tetrahedral orientation in comparison to that of any other Silicate variation higher up on the reation series latter. Feldspar is one of the most stable variations in orientation of, what boils down to, silicate tetrahedra. Because Feldspar is technically a form of silicate tetrahedra orientation, I am assuming you are asking how the silicate tetrahedra orientations vary from its most simple (i.e. Olivine) to its mosts complex (i.e. quartz/FELDSPAR) forms. Esentially a Silicate Ion SiO4^-4 is the most basic building block of FELDSPAR. Knowing this, as you move from the top of Bowen's reaction series, we see a gradual stabilization of the various Silicate tetrahedral orientations. These orientations include (in order of stability/complexity): [TOP OF REACTION SERIES] Individual (Singular form) Silicate Tetrahedra (i.e. Olivine) Chain (Linear form) Silicate Tetrahedra (i.e. Pyroxine) Double Chain (Bilinear form) Silicate Tetrahedra (i.e. amphibole) Sheet Silicate Tetrahedra ('2-D' form) (i.e. Mica: Biotite or Muscovite) Framework Silicate Tetrahedra ('3-D' form) (i.e. FELDSPAR) [BOTTOM OF REACTION SERIES]

Is a stalagmight up?
A stalagmite is a build up of silicate on the base of a cave, many times in the shape of a cone with the base on the floor of the cave, as it extends to the ceiling.
Is limonite in paint?
no
What is LIMONITE used for?
limonite is used for changing the color of paint from red to yellow. and made in white paint
What is the hardness of Limonite on the mohs hardness scale?
The hardness of Limonite is 4 t0 5.5 on the mohs hardness scale.
What are uses of limonite?
limonite is a minor ore of iron, it is used in Chinese in medicine and it is used in white paint.
What is the chemical make-up of limonite?
Limonite is an iron ore; the approximative composition is FeO(OH).nH2O.
What mineral group does limonite belong to?
Limonite belongs to the mineral group known as oxides and hydroxides.
Does limonite have fracture?
yes it does
What color is limonite?
Limonite is a natural iron ore. Limonite can be found in various shades of brown, yellow, orange and combinations of the three.
What is produced when iron-bearing silicate minerals in the desert landscape oxidize?
Iron-bearing silicate minerals in the desert landscape oxidize when exposed to air and moisture, producing iron oxide minerals such as hematite and limonite. These minerals give the soil a red or orange color commonly seen in desert regions.
What is the mineral group of limonite?
Limonite is only a synonym for goethite. Goethite Chemical formula: Fe3+O(OH) Crystal system: orthorombic bipyramidal Dana class: Hydroxides and oxides containing hydroxyl Synonym: limonite
Does limonite have cleavage or fracture?
Limonite typically displays a fracture rather than cleavage. Its structure lacks distinct planes of weakness that would allow it to exhibit cleavage. Instead, limonite breaks irregularly along its surfaces due to its uneven internal structure.
How can the streak test be used to identify the two iron minerals limonite and hematite?
Hematite has a red streak. It can vary in depth of color, depending on the variety of hematite. Limonite has a yellow-brown (More brown than yellow) streak. But you have to make sure you are streaking the limonite and not an underlying mineral, if the limonite is located on another mineral.
