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

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.
In the given redox reaction, calcium (Ca) is oxidized to calcium ions (Ca²⁺). The oxidation half-reaction can be represented as: [ \text{Ca} \rightarrow \text{Ca}^{2+} + 2e^- ] This shows that solid calcium loses two electrons as it is converted into calcium ions.
The oxidation states of calcium are +2, +1. It is considered to be a strongly basic oxide.
The word equation for the reaction between calcium and phosphorus is: calcium + phosphorus → calcium phosphide.
The word equation for calcium reacting with oxygen is: calcium + oxygen → calcium oxide.
