CaF2
CaSO4 is Calcium Sulphate. Do not confuse with :- CaSO3 which is Calcium Sulphite CaS which is Calcium sulphide. Note the ONE letter difference in the sulphur anion spelling.
The correct formula for the ionic compound composed of calcium and chlorate is Ca(ClO3)2. Calcium has a 2+ charge and chlorate (ClO3) has a 1- charge, so you need two chlorate ions to balance the charge of one calcium ion.
The correct formula for the molecular compound heptaphosphorus octafluoride is P₇F₈. It consists of 7 phosphorus atoms bonded to 8 fluorine atoms.
The names "Calcium and sulfur" and "Sulfur calcium" are incorrect because they do not follow the standard naming conventions for chemical compounds. In this case, the correct name for the compound formed by calcium and sulfur would be calcium sulfide.
The question must be CoI3 Cobalt (III) iodide.
The correct name of the compound CaCl2*6H2O is calcium chloride hexahydrate.
Aluminum fluoride is AlF3. It has 3 fluorine atoms for each aluminum atom.
CaO is the chemical formula of calcium oxide.
CaSO4 is Calcium Sulphate. Do not confuse with :- CaSO3 which is Calcium Sulphite CaS which is Calcium sulphide. Note the ONE letter difference in the sulphur anion spelling.
The calcium salt should be Ca(ClO2)2, Calcium chlorite.
calcium oxide (A+)
CuCI is made out of calcium and chlorine . The compound is called calcium chlorine.
Pure fluorine usually exists as a diatomic compound, formula F2.
The correct molecular formula for iodine pentafluoride is IF5. It consists of one iodine atom and five fluorine atoms in the compound.
The formula CaCl2 represents the compound calcium chloride. It consists of calcium ions (Ca2+) and chloride ions (Cl-). The subscript "2" indicates that there are two chloride ions for every one calcium ion in the compound.
It is calcium chloride .But it exists as CaCl2.2H2O in its hydrated state.
