+2, +6, and -2 respectively
The oxidation number of Calcium (Ca) is +2
The formula for calcium sulfate is CaSO4. Oh yah im smart!
+4 oxygen has an oxidation of -2, so do 3 times -2=-6, i believe Ca is a +2 and you must get the numbers to equal 0. so the answer is a +4
Oxidation number is plus two. It is common to every ion of Ca.
-1 for Carbon (in carbide) and +2 for Ca
The only oxidation number is 2+.

-1 for Carbon (in carbide) and +2 for Ca
Ca + H2SO4 = CaSO4 + H2
Ca is 2+ and P is 3-
+2 for Ca in its compounds
+2 for Ca, +6 for Cr, -2 for each O
0 for the elemental form +2 in its compounds
This is a chemical reaction equationH2SO4(aq) + Ca(OH)2(s) --> CaSO4(s) + 2H2O(l)
