O.S. of Na = +1

O.S. of Cr = +6

O.S. of O = -2

O.N. of cpd = 0

The oxidation number of antimony (Sb) in Sb3O5 is +5. Oxygen typically has an oxidation number of -2, so by setting up an equation where the total oxidation numbers of the atoms equals the charge of the compound (0 in this case), we can determine the oxidation number of antimony in Sb3O5 to be +5.

In AgNO3, silver (Ag) has an oxidation number of +1, nitrogen (N) has an oxidation number of +5, and oxygen (O) has an oxidation number of -2. This is because the overall compound is neutral, so the sum of the oxidation numbers must equal zero.

The supernova SN 1006 is believed to have emitted a blue-white light when it exploded in the year 1006, based on historical records and modern astronomical simulations.

D-Gulonic acid

Zero The oxidation number of an element in any of its elemental forms (allotropes) is always zero

The oxidation number of sulfur (S) in SO2 is +4. Each oxygen atom has an oxidation number of -2, so in order to balance the charges, sulfur must have an oxidation number of +4.

The oxidation number of hydrogen (H) in HBr is +1. In binary ionic compounds, such as HBr, hydrogen typically has an oxidation state of +1.

Compounds formed from X(III) and Z(II) would have the formula X2Z3, while compounds formed from X(V) and Z(III) would have the formula XZ2.

Zero The oxidation number of an element in its elemental form is always zero.

O.S. of Sn = +2

O.S. of O = -2

O.N. of cpd = 0

I believe K2CO3.

The oxidation number of phosphorus in ATP is +5. This is because each of the four oxygen atoms in the phosphate groups of ATP carries a charge of -2, and the overall molecule is neutral.

O.S. of H = +1

O.S. of O = -2

O.N. of cpd = 0

BA is in the group2. It generally shows +2 oxidation state.

O.S. of Flourine = 0

O.N of cpd = 0

In BaF2, Ba has an oxidation number of +2 and F has an oxidation number of -1. This is because Ba typically forms ionic compounds where it loses 2 electrons to achieve a stable electron configuration, while F gains one electron.

The overall charge of H3PO is 0, and since hydrogen typically has an oxidation state of +1 and oxygen -2, the oxidation number of phosphorus in H3PO is +3 to balance the charges.

Answer this question… Fe3+

This is a compound. Compounds don't have oxidation numbers, only their constituent elements do. If you must have an answer, use 0.

The oxidation number of C in oxalic acid (H2C2O4) is +3. This is because the overall charge of the molecule is 0, and each hydrogen atom has an oxidation state of +1, and each oxygen atom has an oxidation state of -2. Using these numbers and the fact that the sum of all oxidation states in a neutral molecule is 0, you can determine that the oxidation state of carbon in oxalic acid is +3.

The oxidation number of carbon in sucrose is +4. In sucrose (C12H22O11), the carbon atoms are bonded to oxygen atoms through double bonds, causing the oxidation state of carbon to be +4.

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.

O.S of K = +1

O.S. of Ta = +5

O.S. of F = -1

The oxidation number for carbon (C) in carbon dioxide (CO2) is +4. Each oxygen atom has an oxidation number of -2, so in the compound CO2, the total oxidation number must equal 0.
