+2, +6, and -2 respectively
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.
Since the SO4-2 ions have two negative charges and oxygen atoms in almost all compounds have two negative charges each, the sulfur atoms have an oxidation number of -2 -4(-2) = +6.
The oxidation number of Calcium (Ca) is +2
The oxidation number of calcium (Ca) is +2 and the oxidation number of phosphorus (P) is -3. Therefore, in Ca₃P₂, the oxidation number of calcium is +2 and the oxidation number of phosphorus is -3.
-1 for Carbon (in carbide) and +2 for Ca

The formula for calcium sulfate is CaSO4. Oh yah im smart!
The molar mass of CaSO4 is 136.14 g/mol. The molar mass of Ca in CaSO4 is 40.08 g/mol. To find the percent composition of Ca by mass, divide the molar mass of Ca by the molar mass of CaSO4 and multiply by 100. This gives a percent composition of approximately 29.4%.
The chemical equation for the reaction between calcium (Ca) and sulfuric acid (H2SO4) is: Ca + H2SO4 -> CaSO4 + H2. This reaction produces calcium sulfate (CaSO4) and hydrogen gas (H2).
Of course not. No change in neutrons. Number of electrons decrease
The balanced equation is Ca(OH)2 + H2SO4 → CaSO4 + 2H2O.
The oxidation number of Ca is 0 in its elemental form and is +2 in its compounds.
