What is the oxidation number of Ca?
The oxidation number of Calcium (Ca) is +2
What is the oxidation number of O in SO4?
Oxygen atoms are generally considered to have an oxidation number of -2 in all oxyanions such as sulfate.
What is the oxidation number for Al2O3?
+3 for Al and -2 for O is the oxidation number for Al2O3.
What is the oxidation number of SO4?
+6: Oxygen in oxyanions is assumed to have an oxidation state of -2; there are four such oxygen atoms, for a total of -8, and the SO4 anion has a charge of -2. This means that the sulfur atom must have an oxidation state of +6, because +6 added to - 8 = -2.
What is the oxidation number of Cr in Cr2(SO4)3?
Chromium is a useful element. It shows +2 in this compound.

What is the oxidation state of an individual carbon atom in CaCO3?
+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
What is the oxidation numbers for SO4?
This should be SO4-2 ion. sulfur shows +6 in this ion.
What is Oxidation numbers for SO4?
This should be SO4-2 ion. sulfur shows +6 in this ion.
WHAT IS THE OXIDATION NUMBER OF AL2(SO4)3?
Aluminium is a light metal. Al shows +3 in aluminium sulfate.
Oxidation number of calcium in bleaching powder?
Oxidation number is plus two. It is common to every ion of Ca.
What is the common oxidation numbers for calcium?
The only oxidation number is 2+.
What is the new oxidation number for cr2o7-2 plus 8h plus 3so3-2 2cr3 plus 3sov-2 plus 4h20?
oxidation number of S is +6.It oxidize into SO4 ^-2
