We can find this in bleaching powder. Chlorine shows +1 oxidation number.
The oxidation number of carbon in carbonate (CO3^2-) is +4. Oxygen has an oxidation number of -2, so the three oxygen atoms contribute a total of -6. To balance the charge of -2 for the entire carbonate ion, the carbon atom must have an oxidation number of +4.
+2 for Mg, +4 for C, -2 for each O in MgCO3
Thallium has an oxidation number of +1. Therefore, the formula for thallium carbonate would be Tl2CO3.
The oxidation number of sulfur in sodium bisulfate is +5. In bisulfate ion (HSO4-), the overall charge is -1, so the oxidation number of sulfur can be calculated as -1, taking into account the oxidation number of sodium as +1.
To find the number of moles of sodium carbonate in 57.3g, divide the given mass by the molar mass of sodium carbonate. The molar mass of sodium carbonate (Na2CO3) is 105.99 g/mol. Therefore, 57.3g / 105.99 g/mol = 0.54 mol of sodium carbonate.
Na2C03 Oxidation number of Na = + 1 Oxidation number of O=-2, Oxidation number of C=2x1+x+3(-2)=0 so x=4

Magnesium and carbonate are divalent.
The oxidation number of sulfur in sodium bisulfate is +5. In bisulfate ion (HSO4-), the overall charge is -1, so the oxidation number of sulfur can be calculated as -1, taking into account the oxidation number of sodium as +1.

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.
+3 for each Al; +4 for each C; -2 for each O
The number of water molecules in sodium carbonate decahydrate (washing soda) is 10, which means there are 10 water molecules per unit of sodium carbonate.
a
Yes, sodium carbonate can form hydrates, such as sodium carbonate decahydrate (washing soda). This means that the compound contains a specific number of water molecules within its crystal structure.
