I'm pretty sure it's -2 because everywhere i look i find the chemical formula as being NaHCO3 and if you add up those oxidation numbers then you get -2.
NaHCO3 is the chemical formula f sodium bicarbonate.Carbon is here tetravalent.
Sodium plumbate has the formula Na2PbO3, while sodium plumbite has the formula Na2PbO2. The main difference between them is in the oxidation state of lead; in sodium plumbate, lead is in the +4 oxidation state, while in sodium plumbite, lead is in the +2 oxidation state.
Sodium oxide (Na2O) is primarily considered an oxidizing agent. In its formation, sodium (Na) is oxidized from its elemental state (0 oxidation state) to +1, while oxygen (O2) is reduced from 0 to -2 oxidation state. Thus, in reactions where sodium oxide participates, it can facilitate the oxidation of other substances.
Cryolite, with the chemical formula Na3AlF6, contains sodium (Na), aluminum (Al), and fluorine (F). In this compound, sodium has an oxidation state of +1, aluminum has an oxidation state of +3, and fluorine has an oxidation state of -1. Therefore, the overall oxidation states are: Na (+1), Al (+3), and F (-1).
Sodium Bicarbonate.
The answer is NaHCO3
NaHCO3 is the chemical formula f sodium bicarbonate.Carbon is here tetravalent.
Sodium Oxide, or NaOH, has no oxidation state. It has a charge, which is zero. The elements that make up NaOH, however, do have oxidation states. The oxidation state of sodium (Na) is +1, and it will forever be +1 because it is impossible for it to be anything else, no matter what situation. The same applies for Hydrogen. Oxygen has an oxidation state of -2, and almost always will have an oxidation state of -2. There is one notable exception: H2O2. In this case, since the total charge of the compound is neutral and the oxidation state of Hydrogen must be +1 and, seeing as there are two hydrogens, bringing the overall charge up to 2, the oxidation state of oxygen must be -1. If it was -2, then the molecule would have an overall charge of -2.
The chemical formula for sodium bicarbonate is NaHCO3.
NaHCO3 is sodium bicarbonate. NaC2H3O2 is sodium acetate.
2Na + Cl2 -> 2NaCl. The oxidation state of the sodium ion in NaCl is +1 and the oxidation state of Chloride ion is -1. Oxidation states of the elemental reactants is zero (as for all elements)
The chemical formula for sodium bicarbonate is NaHCO3.
The scientific abbreviation for sodium bicarbonate is NaHCO3.
Sodium bicarbonate (NaHCO3) is considered basic.
The Chemical Formula for Sodium Bicarbonate is NaHCO3.
Sodium plumbate has the formula Na2PbO3, while sodium plumbite has the formula Na2PbO2. The main difference between them is in the oxidation state of lead; in sodium plumbate, lead is in the +4 oxidation state, while in sodium plumbite, lead is in the +2 oxidation state.
Its oxidation number is -1, which is uncommon for hydrogen.
