Chromium(III) sulfide can be prepared through the reaction of a stoichiometric mixture of the elements at 1000 °C [2] + It is a solid that is insoluble in water.
Chromium(II) sulfide may be formed by reaction of chromium metal with sulfur or hydrogen sulfide at high temperature. It may also be formed by reacting chromium(III) chloride with H 2 S, reducing chromium(III) sulfide with hydrogen, or by double replacement reaction of lithium sulfide with chromium(II) chloride.
The Pourbaix diagram for chromium in pure water, perchloric acid, or sodium hydroxide [1] [2]. Chromium compounds are compounds containing the element chromium (Cr). Chromium is a member of group 6 of the transition metals.
Three chromium(III) sulfates are well characterized: Anhydrous chromium(III) sulfate, Cr 2 (SO 4) 3, (CAS #10101-53-8) is a violet solid that dissolves in water upon addition of a reducing agent.
This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately.
Because of its considerable stability, chromia is a commonly used pigment. It was originally called viridian.It is used in paints, inks, and glasses. It is the colorant in "chrome green" and "institutional green."
The table is sortable by each of the following refrigerant properties (scroll right or reduce magnification to view more properties): Type/prefix (see legends); ASHRAE number
Drifting smoke particles indicate the movement of the surrounding gas.. Gas is one of the four fundamental states of matter.The others are solid, liquid, and plasma. [1] A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).
