I believe K2CO3.
The oxidation number of carbon in HNC is -4. This is derived by assigning hydrogen a +1 oxidation number and nitrogen a -3 oxidation number, then solving for carbon's oxidation number based on the overall charge of the compound.
The oxidation number for carbon in CHI3 compound is -2. In CHI3, iodine has an oxidation number of -1 and hydrogen has an oxidation number of +1, which allows carbon to have an oxidation number of -2 to balance the overall charge of the compound.
The oxidation number for carbon in C2H6O is -3. This is calculated by assigning hydrogen an oxidation number of +1 and oxygen an oxidation number of -2, then applying algebra to determine the oxidation number of carbon.
The oxidation number of carbon in formaldehyde (HCHO) is +2. In this molecule, oxygen has an oxidation number of -2, and hydrogen has an oxidation number of +1. By applying the rules for assigning oxidation numbers in a compound, we can determine that carbon has an oxidation number of +2.
I believe K2CO3.
In the reaction between potassium oxide (K2O) and carbon dioxide (CO2), potassium is in the +1 oxidation state in K2O and carbon is in the +4 oxidation state in CO2. When they combine, potassium oxide reacts with carbon dioxide to form potassium carbonate (K2CO3). In potassium carbonate, potassium is in the +1 oxidation state and carbon is in the +4 oxidation state.

The oxidation number of carbon in CH3OH is -2. This is because hydrogen has an oxidation number of +1 and oxygen has an oxidation number of -2. By assigning these values to the other atoms in the molecule, we can determine that carbon must have an oxidation number of -2 to balance the overall charge of the molecule.
In CH3OH, the oxidation number of carbon (C) is -2. In HCOOH, the oxidation number of carbon (C) is +2.
In KO2, O has an oxidation number of -1, K has an oxidation number of +1. In CO2, O has an oxidation number of -2, C has an oxidation number of +4. In K2CO3, O has an oxidation number of -2, C has an oxidation number of +4, and K has an oxidation number of +1. In the given reaction, the oxidation numbers for each atom remain the same as in their individual compounds.
Potassium carbonate has 8,69 % carbon and 8,6 g K2CO3 have 0,75 g carbon.
The oxidation number of carbon in CO is +2. This is because the oxidation number of oxygen is typically -2, and there is only one oxygen atom in CO, so the oxidation number of carbon must be +2 to balance the charge.
The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
