The chemical formula for Barium Carbonate is BaCO3
NiCO3 is the chemical formula for nitrogen carbonate.
The formula and charge for the carbonate ion is CO32- and the formula and charge of the magnesium ion is Mg2+. Together they make magnesium carbonate, MgCO3.
Cesium Carbonate = Cs2CO3
The chemical formula of sodium carbonate is Na2C03. The chemical formula of calcium chloride is CaCl2.
The Chemical Formula for Aluminum carbonate is Al2(CO3)3
The name of the compound with chemical formula Al2(CO3)3 is aluminum carbonate. This compound if composed of 2 aluminum atoms and 3 carbonate groups.
Al2(CO3)3
Aluminium Hydroxide - Al(OH)3Magnesium Carbonate - MgCO3
I greatly doubt that aluminium bicarbonate exists. The bicarbonate ion requires a large, non-polarising cation for stability, and aluminium ions are small and highly polarising. There is even dispute whether aluminium carbonate exists.
It's aluminum carbonate.
Al2(CO3)3
Silver carbonite is not a chemical compound, it is the color scheme for a number of computer peripherals. If this was meant to be silver carbonate the chemical formula for this chemical compound is Ag2CO3.
The formula for silver carbonate is Ag2CO3
The chemical formula for Barium Carbonate is BaCO3
Aluminum carbonate is Al2(CO3)3. If you have 7.0x1022 particles of it, then that's 7.0x1022/6.02x1023 = 0.116 moles. The compound has a molar mass of 234g/mol, so 234x0.116=27.144 grams.
The formulae are respectively Al2(CO3)3, CCl4 and NaCN.
