The oxidation number of sodium (Na) in sodium carbonate (Na2CO3) is +1. The oxidation number of oxygen (O) is -2, and the oxidation number of carbon (C) is +4. Therefore, the overall compound has a charge of 0.
In sodium oxide (Na2O), sodium typically has an oxidation number of +1 and oxygen has an oxidation number of -2. Sodium readily gives up its outer electron to achieve a full valence shell, while oxygen typically gains two electrons to achieve a full valence shell.
To determine the number of sodium ions in 85g of sodium oxide (Na2O), first calculate the molar mass of Na2O. This can be done by adding the atomic masses of sodium (Na) and oxygen (O) in the compound. Then, find the number of moles of Na2O in 85g using the molar mass. Since Na2O contains 2 sodium ions per formula unit, multiply the number of moles by 2 to find the number of sodium ions.
The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
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.

No, Na2O does not have a Roman numeral. When we talk about sodium oxide (Na2O), we are dealing with sodium and oxygen. We know that sodium has a +1 oxidation state in nearly everything it reacts with. You can pretty much bet on it. As it is essentially always going to combine in this +1 oxidation state, there is no need to differentiate that oxidation state from another one, which is what Roman numerals do.Oxygen has (almost always) a -2 oxidation state, and that means it takes two +1's to balance with a -2. Sodium, with its +1 oxidation state, will combine in a two-to-one ratio with oxygen, with its -2 oxidation state, to make the oxide.

Na2O or sodium oxide is an ionic compound.The formula mass of Na2O is 2(23.0) + 16 = 62.0 Amount of Na2O = 6.2/62.0 = 0.1mol In each formula unit of Na2O there are two singly positively charged Na+ ions. So, amount of sodium ions = 0.2 moles.
