Ca(NO2)2
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 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).
calcium cation = Ca2+ carbonate ion = CO32- the charges should cancel and you have the correct formula
CaI2, this is the correct formula for calcium iodide
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.
Ca(NO2)2
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.
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).
calcium cation = Ca2+ carbonate ion = CO32- the charges should cancel and you have the correct formula
The charge of Ca2+ is correct. Calcium typically oxidizes to form a 2+ cation by losing two electrons.
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.
CaI2, this is the correct formula for calcium iodide
CaCO3 is calcium (Ca2+) carbonate (CO32-)
