C=4

n= -3

oxygen is -2

OCN has net charge of -1 so here is my expalnation

we will take C as unknown

-2+x-3=-1

x=4

now N is the unknown :

-2+4+x=-1

x=-3

and Oxygen is always -2 except peroxides and others cases...

hope i helped !

The oxidation number of nitrogen in HCN (hydrogen cyanide) is -3. This is because hydrogen has an oxidation number of +1 and carbon has an oxidation number of -1, leaving nitrogen with an oxidation number of -3 to balance out the charge of the molecule.

The oxidation no of c in HCN and HNC IS?

In both HCN and HNC molecules, the oxidation number of carbon (C) is -3. This is because hydrogen (H) is almost always assigned an oxidation number of +1, and nitrogen (N) is usually assigned an oxidation number of -3. By assigning the oxidation numbers of H and N, we can then determine the oxidation number of C that makes the overall charge of the molecule neutral.


What is the minimum oxidation number for nitrogen?

The minimum oxidation number for nitrogen is -3.


What is the Oxidation number of nitrogen in ammonium nitrite?

The oxidation number of nitrogen in ammonium nitrite (NH4NO2) is +3. In the ammonium ion (NH4+), nitrogen has an oxidation number of -3 and in the nitrite ion (NO2-), nitrogen has an oxidation number of +3.


The oxidation number of nitrogen in N2 is?

The oxidation number of nitrogen in N2 is 0 since it is in its elemental form where the oxidation number is always 0.


What is the oxidation number in NH3?

The oxidation number of hydrogen in NH3 is +1, and the oxidation number of nitrogen is -3. This is because hydrogen typically has an oxidation number of +1 and in compounds, nitrogen usually has an oxidation number of -3.


What is the oxidation number of nitrosyl?

The oxidation number of nitrosyl (NO) is +1. Nitrogen typically has an oxidation number of -3, and oxygen typically has an oxidation number of -2. In NO, nitrogen has a -3 oxidation number and oxygen has a -2 oxidation number, leading to an overall oxidation number of +1 for the nitrosyl ion.


What is the oxidation number of N O?

The oxidation number of nitrogen (N) in nitric oxide (NO) is +2.


What is the oxidation number of nitrogen in NO?

The oxidation number of nitrogen in NO is +2. This is because oxygen has an oxidation number of -2, and since the overall charge of NO (nitrogen monoxide) is 0, the nitrogen atom must have an oxidation number of +2 to balance the equation.


What is the oxidation number of nitrogen in NO 2?

The oxidation number of nitrogen in NO2 is +4. Each oxygen atom has an oxidation number of -2, and since the overall charge of NO2 is 0, the nitrogen atom must have an oxidation number of +4 to balance the charges.


What is the oxidation number of nitrogen in hydrazine?

The oxidation number of nitrogen in hydrazine (N2H4) is -2. This is because hydrogen usually has an oxidation number of +1, and in this case, since there are two hydrogens bonded to each nitrogen, the total oxidation number for nitrogen must be -2 to balance it out.


What the oxidation number of Nitrogen?

The oxidation number of nitrogen can vary depending on the compound it is in. In most cases, nitrogen has an oxidation number of -3 when it is in its elemental form or in compounds like ammonia (NH3). However, in compounds like nitrate (NO3-), nitrogen has an oxidation number of +5.


What is the oxidation number of nitrogen in nitrogen dioxide?

The oxidation number of nitrogen in nitrogen dioxide (NO2) is +4. Each oxygen atom in NO2 has an oxidation number of -2, and since the molecule is neutral, the sum of the oxidation numbers must equal zero. Therefore, the oxidation number of nitrogen is calculated as follows: 2(-2) + x = 0, where x represents the oxidation number of nitrogen. Solving for x gives x = +4.
