This ratio in CaO is 1.
It is CaO, not Ca2. And there is no such thing as calcium II, because the Ca2+ cation that calcium forms is the ONLY cation that it forms. This is true for almost all of the all of the alkali and alkaline earth metals. So it would just be Calcium Oxide, even though it has a plus 2 charge. The (II) is only necessary if the element forms more than one type of ion.
Ratio by Mass: 3 : 10 : 7
formula unit
The ratio aluminium/oxigen is 0,66 in Al2O3..
The ions are: Ca2+ and Cl-; the ratio chloride ions/calcium ions is 2.
Calcium carbonate would be an ionic compound composed of the cation Ca2+ and the polyatomic anion CO32-. Combining these ions in a 1:1 ratio causes the charges to balance, so the formula would be CaCO3.
Calcium oxide, CaO: the ratio is 1.
The ratio of Ca2+ ions to stearate anions depends on the specific compound or salt being referred to. For example, in calcium stearate (Ca(C17H35COO)2), the ratio is 1:2, with one Ca2+ ion for every two stearate anions. However, in other compounds, such as calcium di(stearate) (Ca(C17H35COO)2), the ratio may vary.
As Calcium Has been used for Building Purpose And For the Similar purpose it is Using IN Cement Which Depend upon its Bonding Property.It Actually react with Water in the Presence of Sesqui oxide(oxygen with Cation in (3:2) ratio) and form a Complex Compound With water of Crystalline Which have A power to hold the Material and So called cement.

The Chemical Formula for Calcium Oxide is CaO.
No. Sodium chloride has a crystal lattice structure in which each sodium cation is surrounded by six chloride anions, and each chloride anion is surrounded by six sodium cations. The ratio of sodium cations to chloride ions is 1:1, which is reflected in its chemical formula NaCl, which is called a formula unit.
That's silver(I) perbromate. Silver's most common valence state is +1. The perbromate anion has one more oxygen than the "parent" bromate polyatomic, hence the "per-" prefix. The charge of perbromate is -1. Therefore, the silver cation and the perbromate anion bond in a 1:1 ratio with the formula AgBrO4.
2:1
MgCl2 is an ionic compound with the Mg2+ cation and the Cl- anion in a 1:2 ratio. In each formula unit of MgCl2 there are two Mg2+ and one Cl- ion. So in 4 moles of MgCl2 there will be 12 moles of ions.
Calcium to Phosphorus : 2 : 1
No. The formula unit for an ionic compound denotes the ratio of ions in the compound. For example, the formula unit NaCl indicates a ratio of 1 sodium ion to 1 chloride ion, CaCl2 indicates a ratio of 1 calcium ion to 2 chloride ions, and Fe2O3 indicates a ratio of 2 iron ions to 3 oxide ions.
