C is +4, each oxygen is -2
The oxidation number of carbon (C) in CO3^2- is +4. This is because the sum of the oxidation numbers in the carbonate ion must equal its charge of -2, and oxygen is typically assigned an oxidation number of -2.
The oxidation number of each copper (Cu) atom in CuCO3 is +2. The oxidation number of the oxygen (O) atoms in the carbonate ion (CO3) is -2, and the overall charge of the carbonate ion is -2.
The oxidation number of Fe in FeCO3 is +2. This is because the overall charge of the carbonate ion (CO3^2-) is -2, so the iron (Fe) must have an oxidation state of +2 to balance the charge of the compound.
H is +1, O is -2 overall carbon will have an oxidation # of -3
+1 to each H +4 to each C -2 to each O
+2 for Mg +4 for C -2 for each O

+1 to each H +4 to each C -2 to each O
The oxidation number of Ca is 0 in its elemental form and is +2 in its compounds.
The oxidation number of carbon (C) in CH2O is +2. This is because hydrogen (H) has an oxidation number of +1 and oxygen (O) has an oxidation number of -2, so the sum of the oxidation numbers in CH2O must be zero to balance the charge.
CO is a harmful gas.C shows +2 in CO and it shows +4 in CO2.
The oxidation number is + for C and -2 for O.
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.
The oxidation number of C in FeCO3 is +4. This can be determined by assigning the oxidation number of +2 to Fe and -2 to each O atom, and then solving for C based on the overall charge of the compound.
