+3
-1 for Carbon (in carbide) and +2 for Ca
The oxidation number of Ca is 0 in its elemental form and is +2 in its compounds.
The oxidation number of carbon (C) in Al4C3 is -4. This is because aluminum (Al) has an oxidation number of +3 and there are 4 aluminum atoms for a total oxidation number of +12. This must be balanced by the oxidation numbers of the carbon atoms, which must be -4 in order for the compound to be neutral.
The oxidation number of C in C₂O₄ is +3. Each oxygen atom carries a charge of -2, and since there are 4 oxygen atoms in total with a total charge of -8, the carbon atom's oxidation number must be +3 to balance the charges in the compound.
The central carbon atom has an oxidation number of -2 (O is -2, H is +1)
-1 for Carbon (in carbide) and +2 for Ca
The oxidation number of Ca is 0 in its elemental form and is +2 in its compounds.
CaC2 It is also called Calcium Acetylide which describes the structure better. It forms a chain with a triple bond between the Carbon atoms -Ca-C---C-Ca-C---C-Ca- etc.
The oxidation number of carbon (C) in Al4C3 is -4. This is because aluminum (Al) has an oxidation number of +3 and there are 4 aluminum atoms for a total oxidation number of +12. This must be balanced by the oxidation numbers of the carbon atoms, which must be -4 in order for the compound to be neutral.
The oxidation number of C in C₂O₄ is +3. Each oxygen atom carries a charge of -2, and since there are 4 oxygen atoms in total with a total charge of -8, the carbon atom's oxidation number must be +3 to balance the charges in the compound.
The central carbon atom has an oxidation number of -2 (O is -2, H is +1)
The oxidation number of C in C2O4^2- is +3. This is because each O atom is assigned an oxidation number of -2, and the overall charge of the ion is -2, so the two C atoms must have a total oxidation number of +6 in order to balance the charge.
In calcium carbide (CaC2) are 1 atom of Calcium and two of Carbon, so totally three atoms of two elements
The oxidation value (number) of C atom in carbide (not corbide) is -1, and of Ca always +2. This makes one Ca reacting with two C atoms in forming CaC2.Calcium Carbide is a common but improper name for CaC2.It's proper name is Calcium Acetylide.In Calcium Acetylide there are three covalent bonds joining the Carbon atoms, andthe forth bond of each Carbon go to Calcium forming an ionic bond.Crystal structure :The common crystalline form at room temperature is tetragonal, a distorted rock salt structure with the C22− units lying parallel.(Cf. 'Related links' for ionic picture)
Assuming you mean what is the oxidation number of each atom in the compound C3H8O? Oxidation rules state the the sum of all oxidation numbers in a neutral molecule equals 0. 1. O = -2 2. H = +1 3. C = -2 These numbers are derived from... (-2) + (+1 x 8) + (-2 x 3) = 0
The oxidation number of Ca in CaC2O4 is +2 because Ca, a group 2 element, typically has a +2 oxidation state in compounds. The oxidation number of C in C2O4 is +3 because the overall charge of the oxalate ion is -2, and there are two C atoms, each with an oxidation state of +3 to balance the charge.
The oxidation number for C in NH2CONH2 is +2. This is because each hydrogen has an oxidation number of +1, and oxygen has an oxidation number of -2. By assigning hydrogen and oxygen their usual oxidation numbers, we can determine that the nitrogen atoms in NH2CONH2 have an oxidation state of -3, and since each nitrogen atom contributes three electrons to the carbon atom, the overall oxidation state of carbon is +2.
