2Ca + O2 = 2 CaO
In CaSO4 (calcium sulfate), the oxidation number of calcium (Ca) is +2, as it typically forms ionic compounds with a 2+ charge. Oxygen (O) usually has an oxidation number of -2 in compounds, so in CaSO4, the total oxidation number of the oxygen atoms is -8. To find the oxidation number of sulfur (S), we can set up the equation: 2(+2) + x + 4(-2) = 0, where x represents the oxidation number of sulfur. Solving this equation gives us the oxidation number of sulfur as +6.
Calcium is a element. Nitrate is a ion. Calcium shows +2.
The oxidation state of calcium in calcium hydride is +2, as calcium typically forms ionic compounds with a +2 oxidation state.
The oxidation number of Calcium (Ca) is +2
Scandium has a higher oxidation state than calcium. Scandium typically exhibits a +3 oxidation state, while calcium usually shows a +2 oxidation state.
I'm sure it's an oxidation reaction. calcium + oxygen gas ---> Calcium oxide

Calcium Sulphide is the name(word) of the substance. It chemical formula is 'CaS'. That is one atom of calcium one atom of sulphur. NB Carefukl with the nameing oif sulphur compounds. 'Sulphate' = -SO4' (Four oxygens). CuSO4 ; Copper SULPHATE) 'Sulphite' = -SO3' (Three oxygen). (CuSO3 ; Copper SULPHITE) 'Sulphide' = -S' (No oxygens). (CuS ' Copper SULPHIDE). Note the subtle change of one letter to indicate a different sulphur type compound.
Scandium has a higher oxidation state than calcium. Scandium typically exhibits a +3 oxidation state, while calcium usually shows a +2 oxidation state.
The oxidation number of calcium in the compound CaOCl2 is +2. In compounds, the sum of the oxidation numbers must equal zero, and since oxygen has an oxidation number of -2 and chlorine has an oxidation number of -1, the calcium ion must have an oxidation number of +2 to balance the charges.
The oxidation states of calcium are +2, +1. It is considered to be a strongly basic oxide.
The word equation for calcium reacting with oxygen is: calcium + oxygen → calcium oxide.
The word equation for the reaction between calcium and phosphorus is: calcium + phosphorus → calcium phosphide.
