Oxidation Numbers

The phosphate anion is PO4^(3-)

Using oxygen as the standard at '-2' .

The nthe oxygen moiety is 4 X -2 = -8

Since the overall charge on the anion is '-3'

Then we can make a sum

P + - 8 = -3

Add '8' to bothe sides

P = +5 The oxidation state of phosphorus.

Alkali metals have a single electron in their outermost shell that is easily lost, resulting in a positive oxidation number. When they lose this electron to form ions, they attain a stable electron configuration, which typically involves having a full valence shell with a noble gas electron configuration.

The oxidation number for carbonate is -2, as it is composed of one carbon atom with a formal charge of +4 and three oxygen atoms each with a formal charge of -2. The oxidation number for barium is +2, as it is a group 2 element in the periodic table, meaning it typically forms 2+ cations.

MnO2: oxidation number +4
KMnO4: oxidation number +7

The oxidation number of Br in BrO3- is +5. This is because oxygen typically has an oxidation number of -2, and since there are three oxygen atoms in the BrO3- ion, the total negative charge is -6. Since the overall charge of the ion is -1, the oxidation number of Br must be +5 to balance the charges.

In CaN2, nitrogen (N) has an oxidation number of -3. To find this, we know that the overall charge of CaN2 is zero (Ca is +2), so the two nitrogens must have a total charge of -6, making the oxidation number of each nitrogen -3.

The oxidation number of silicon (Si) in SiO2 is +4. Oxygen (O) typically has an oxidation number of -2, so in this compound, the total oxidation number must equal zero. Since there are two oxygen atoms in SiO2, the oxidation number of silicon must be +4 to balance out the -4 from the oxygens.

The oxidation number of Li in LiNO2 is +1, as it typically has an oxidation number of +1 in its compounds.

The oxidation number of Mg in MgCO3 is +2, the oxidation number of C in CO3 is +4, and the oxidation numbers of O in CO3 are -2.

The oxidation number of Cl in HClO4 is +7 because oxygen has an oxidation number of -2 and hydrogen has an oxidation number of +1. By using the sum of the oxidation numbers in a compound, we can calculate the oxidation number for Cl as +7.

No, an oxyacid is a compound that contains hydrogen, oxygen, and a nonmetal. It does not need to have exactly 2 atoms, as the number of atoms can vary depending on the specific chemical formula of the oxyacid.

The answer to this question is that the oxidation number for the 2nd energy level is +2. This is because the 2nd energy level is the second highest energy level in an atom, and thus has a higher oxidation number than the 1st energy level. The oxidation number for the 2nd energy level is determined by the number of electrons in the 2nd energy level.

+1

With the molecular formula Au2Cl6, the name gold trichloride is a simplification, referring to the empirical formula, AuCl3. The Roman numerals in the name indicate that the gold has an oxidation state of +3, which is common for gold compounds

Turn to non-corrosive metals such as aluminum and stainless steel. Keep the area around the metal surface dry. Use drying agents and moisture barrier products. Make sure underground piping is laid in a layer of backfill, such as limestone. Make sure any electrical components are cleaned regularly.

The sum of the oxidation numbers is zero for the compound.

Negative oxidation typically refers to reduction, which is the gain of electrons or a decrease in oxidation state of a molecule. In this process, a molecule or atom undergoes a reduction reaction by accepting electrons.

P3+

The oxidation state for manganese in Mn is 0, since it is in its elemental form.

The oxidation state for manganese in MnO2 is +4. Oxygen typically has an oxidation state of -2, so the sum of the oxidation states in MnO2 would be 0. Since there are two oxygen atoms with an oxidation state of -2 each, the manganese atom must have an oxidation state of +4 to balance the equation.

The oxidation state of Rhodium (Rh) in the complex (PPh3)3RhCl is +1. This is because each triphenylphosphine ligand (PPh3) contributes -1 charge (-3 total), and the chloride ligand (Cl) contributes -1 charge. Since the overall charge of the complex is neutral, the oxidation state of Rh is +1.

The oxidation number of sulfur in CS2 is -2. In carbon disulfide (CS2), each carbon atom has an oxidation number of +4, which means the two sulfur atoms must have oxidation numbers that add up to -8 to balance the charge of the molecule. Hence, each sulfur atom has an oxidation number of -2.

Chlorine has an oxidation number of +5 in compounds such as perchlorate (ClO4-). This is due to the electronegativity of oxygen, which causes chlorine to have a higher oxidation state in the compound.

The oxidation number of Ca in CaO2 is +1. This is because the oxidation number of O is -2, and since there are two O atoms in CaO2, the overall charge contributed by the oxygen atoms is -4 (2*-2). Therefore, the oxidation number of Ca must be +1 to balance the charges and make the compound neutral.

This should be SO4-2 ion. sulfur shows +6 in this ion.
