Iron(II) chloride, also known as ferrous chloride, is the chemical compound of formula FeCl 2. It is a paramagnetic solid with a high melting point. The compound is ...
Iron(III) chloride describes the inorganic compounds with the formula Fe Cl 3 (H 2 O) x. Also called ferric chloride , these compounds are some of the most important and commonplace compounds of iron.
Potassium ferrioxalate, also called potassium trisoxalatoferrate or potassium tris (oxalato)ferrate (III)[ 3 ] is a chemical compound with the formula K 3[ Fe (C 2 O 4)3]. It often occurs as the trihydrate K3[Fe (C2O4)3]·3H2O. Both are crystalline compounds, lime green in colour. [ 4 ]
Atomic radii of the elements (data page) The atomic radius of a chemical element is the distance from the center of the nucleus to the outermost shell of an electron. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. Depending on the definition, the term may apply only to ...
Glucose (C 6 H 12 O 6), ribose (C 5 H 10 O 5), Acetic acid (C 2 H 4 O 2), and formaldehyde (CH 2 O) all have different molecular formulas but the same empirical formula: CH 2 O.This is the actual molecular formula for formaldehyde, but acetic acid has double the number of atoms, ribose has five times the number of atoms, and glucose has six times the number of atoms.
Ferric. Potassium ferrioxalate contains the iron (III) complex [Fe (C2O4)3]3−. In chemistry, iron (III) or ferric refers to the element iron in its +3 oxidation state. Ferric chloride is an alternative name for iron (III) chloride (FeCl3). The adjective ferrous is used instead for iron (II) salts, containing the cation Fe 2+.
An example of the difference is the empirical formula for glucose, which is CH 2 O (ratio 1:2:1), while its molecular formula is C 6 H 12 O 6 (number of atoms 6:12:6). For water, both formulae are H 2 O. A molecular formula provides more information about a molecule than its empirical formula, but is more difficult to establish.
Iron(II,III) oxide, or black iron oxide, is the chemical compound with formula Fe3O4. It occurs in nature as the mineral magnetite. It is one of a number of iron oxides, the others being iron(II) oxide(FeO), which is rare, and iron(III) oxide(Fe2O3) which also occurs naturally as the mineral hematite. It contains both Fe2+and Fe3+ions and is ...
