The oxidation number of Cr in K 2 Cr 2 O 7 is. Corn, sugar cane, and sorghum are C4 plants. These plants are economically important in part because of their relatively high photosynthetic efficiencies compared to many other crops. To make steel, iron ore is first mined from the ground. It is then smelted in blast furnaces where the impurities are removed and carbon is added. It is a white poisonous clear compound with sweet smell. It is used in making plastics, detergents and drugs.

Chromium Cr , chemical element of Group 6 VIb of the periodic table , a hard, steel-gray metal that takes a high polish and is used in alloys to increase strength and corrosion resistance. Chromium was discovered by the French chemist Nicolas-Louis Vauquelin and isolated as the metal a year later; it was named for its multicoloured compounds. The green colour of emerald , serpentine, and chrome mica and the red colour of ruby are due to small amounts of chromium. Most ores consist of the mineral chromite , the ideal formula of which is FeCr 2 O 4. It is widely dispersed in natural deposits, which are usually contaminated with oxygen, magnesium , aluminum , and silica; their chromium content varies from 42 to 56 percent. One of the chief uses of chromium is in ferrous alloys, for which the pure metal is not required.

What is the oxidation number of chromium in K2Cr2O7? Thank you for your help! Thank you!! Can somebody please explain to me please??????? Hello there!
Oxidation numbers are an arbitrary way of assigning ownership of electrons in a compound. Ionic compounds have a transfer of ownership of the electrons in a very real physical way. A naming system for compounds has been devised to name ionic compounds. Oxidation numbers allow the arbitrary assignment of electron ownership for compounds that are bonded covalently, thus the same naming system can be used for them as well. Using oxidation numbers simplifies nomenclature for many compounds.
