Ca(NO2)2
Calcium sulfide has the chemical formula CaS.
The chemical formula for combining Ca2+ and AsO3^4- ions would be Ca3(AsO3)2. This shows that three calcium ions (Ca2+) will combine with two arsenite ions (AsO3^-4).
Calcium chloride (CaCl2) is a compound that forms by combining one calcium ion (Ca2+) with two chloride ions (Cl-).
The chemical formula for calcium phosphide is Ca3P2
Ca2+ is a cation formed by Calcium to become stable and attain the noble gas configuration of Argon. Calcium forms this cation by losing two electrons
In this reaction, Ca2+ reacts with NO2^1- to form Ca(NO2)2. The balanced chemical equation for this reaction is: Ca2+ + 2NO2^- → Ca(NO2)2.
The correct balanced chemical equation for Ca^2+ reacting with NO2^1- is Ca^2+ + 2NO2^- -> Ca(NO2)2. This equation shows that one calcium ion reacts with two nitrite ions to form one molecule of calcium nitrite.
Ca2+(aq)
Formula: Ca2[Fe(CN)6]
Calcium sulfide has the chemical formula CaS.
In calcium titanate, the formula is typically CaTiO3. In one mole of CaTiO3, there is one mole of Ca2+ ions because the subscript in the formula indicates that there is one Ca2+ ion. Therefore, in 0.25 moles of CaTiO3, there are also 0.25 moles of Ca2+ ions.
The correct chemical formula for the reaction between Ca^2+ and NO2^- is Ca(NO2)2. In this reaction, the calcium ion (Ca^2+) combines with two nitrite ions (NO2^-) to form calcium nitrite.
CaCO3 is calcium (Ca2+) carbonate (CO32-)
The chemical formula for combining Ca2+ and AsO3^4- ions would be Ca3(AsO3)2. This shows that three calcium ions (Ca2+) will combine with two arsenite ions (AsO3^-4).
The ionic formula for Ca2+ and S2- is CaS, which is calcium sulfide. In this compound, calcium donates two electrons to sulfur, forming a ionic bond between the two elements.

The correct ionic formula for Ca2+ and P3- is Ca3P2. The charges on each ion must balance to create a neutral compound, so two Ca2+ ions (2x2 charges) are needed to balance out the three P3- ions (3x(-3) charges).
