The chemical formula of magnesium carbonate is Mg(CO3)2; this molecule contain one ion of magnesium and two ions of carbonate.
Here exist: 1 ion Mg+ and ion (CO3)-.
In a formula unit of magnesium chloride (MgCl2), there are 2 chloride ions present. This is because magnesium has a +2 charge and chloride has a -1 charge, so it takes two chloride ions to balance the charge of one magnesium ion.
Chloride ions have a charge of 1-. Since the charge on an Mg ion is 2+, the formula unit of Magnesium Chloride is MgCl2. There are 2 chloride ions for each Mg ion.
There are two chloride ions present in a formula unit of magnesium chloride. This is because the magnesium ion has a 2+ charge, requiring two 1- chloride ions to balance the charge in a 1:2 ratio.
The chemical formula of magnesium sulfate heptahydrate is MgSO4.7H2O.
There are 6 moles of nitrate ions in 2 moles of magnesium nitrate. This is because there are 3 nitrate ions (NO3-) in each formula unit of magnesium nitrate (Mg(NO3)2). So, 2 moles of Mg(NO3)2 would contain 6 moles of nitrate ions.
The formula for plumbic carbonate is PbCO3. So there is one carbonate ion (CO3)-2 in the unit formula for PbCO3. A more modern name for this compound is lead (II) carbonate.
Please clarify the units of concentration of carbonate and bicarbonate. "mgl" is not a unit of concentration (it's not a unit of anything to my knowledge. To answer this question, you need the concentration of both ions. So either provide the amount of both ions AND the amount of water, or just specify the concentration (in unit of molarity, or moles per liter preferably).
Three. Two chlorine atoms and one magnesium atom.
positive ion - magnesium(cation) negative ion-chloride (anion)
Potassium Phosphate K3PO4 3 K ions and 1 PO4 ion
To determine the number of moles of ammonium ions in 8.738 g of ammonium carbonate, first calculate the molar mass of ammonium carbonate (NH4)2CO3. Then, divide the given mass by the molar mass to find the number of moles. Since there are two ammonium ions in one formula unit of ammonium carbonate, multiply the number of moles by 2 to get the moles of ammonium ions.
