minus 4
The iron(II) ion has +2 charge - Fe2+ The carbonate has -2 charge - CO32- the charge must be balanced so for every one iron(II) ion there should be one carbonate ion. Therefore the formula of Iron(II) Carbonate is: FeCO3
silicon carbide
No. Silicon carbide is covalent.
The valency of Carbide is -4. Yet for some unknown/unexplained reasons Calcium Carbide is CaC2 and not Ca2C.

It can be either. In CO2 it is +4, in a carbide it is -4.
The iron(II) ion has +2 charge - Fe2+ The carbonate has -2 charge - CO32- the charge must be balanced so for every one iron(II) ion there should be one carbonate ion. Therefore the formula of Iron(II) Carbonate is: FeCO3
There are mainly 3 types of carbides, and depending on this the charge of carbon varies : "Most common" Methanide (C4-) = -4 charge Acetylide (C2-2) = -2 charge Sesquicarbide (C3-4) = -4 charge
"Carbide" as used in "Carbide Drills" and "Carbide Saws" is the alloy Tungsten Carbide. Chemically the material is either Tungsten Carbide (WC) or Tungsten diCarbide (WC2). Carbide is used because of its hardness.
No. Silicon carbide is covalent.
silicon carbide
Copper carbide is a salt. As the element implies, the ions present are copper ions and carbide ions. Carbide ions are made of carbon atoms.
Either is acceptable. Other names include Silicon carbide, SiC, Silicon(IV) carbide, Silicon carbide (SiC), Silicon carbide, Carbogran, Carbomant, Carborex, Carborundum, Carsilon, Exolon, Lonsicar, Meccarb, Resilon, Silicone carbide, Silundum, Simax
Union Carbide was created in 1917.
This is calcium carbide - CaC2.
The valency of Carbide is -4. Yet for some unknown/unexplained reasons Calcium Carbide is CaC2 and not Ca2C.
