Calcium iodide has the chemical formula CaI2. To find the percent composition, calculate the molar mass of CaI2, then find the molar mass contributed by each element (calcium and iodine). Finally, divide the molar mass contributed by each element by the total molar mass of CaI2 and multiply by 100 to get the percent composition.
The percent composition of calcium fluoride is approximately 51.1% calcium and 48.9% fluorine.
The percent composition of calcium oxide (CaO) is 71.5% calcium (Ca) and 28.5% oxygen (O).
Calcium iodide.
The percent composition of potassium in potassium iodide (KI) is 58.5%. This is calculated by dividing the atomic mass of potassium by the molar mass of KI and multiplying by 100.
CaC2 is Calcium Carbide. Ca2C does not exist.

The formula of the compound between calcium and sulfur with the given percent composition would be CaS. This is because the ratio of calcium to sulfur atoms in calcium sulfide matches the given percentage composition.
CaC2 is Calcium Carbide. Ca2C does not exist.
Calcium Iodide
If you mean the compound formed from calcium and iodine, it is CaI2. It is named calcium iodide.
Calcium iodide is an ionic compound composed of one calcium ion (Ca2+) and two iodide ions (I-). Therefore, there are a total of 3 ions present in calcium iodide.
Calcium iodide (CaI2) has two iodine atoms and one calcium atom.
Two valence electrons are transferred from the calcium atom to the iodine atom in the formation of calcium iodide. This transfer results in the formation of calcium ions (Ca2+) and iodide ions (I-), which then form an ionic bond to create the compound calcium iodide (CaI2).
The percent composition by element of Ca(C2H3O2)2 is calcium 25.339%, hydrogen 3.824%, carbon 30.375%, and oxygen 40.462%.
