The steric number of NO2 is 3, which is calculated by adding the number of atoms directly bonded to the central atom (N) and the number of lone pairs on the central atom. In this case, the nitrogen (N) atom is directly bonded to 2 oxygen (O) atoms and has 1 lone pair, giving a steric number of 3.

What is the steric number of carbon disulfide?
The steric number of carbon disulfide is 2. This is because carbon has two bonded atoms (sulfur), and there are no lone pairs around the central carbon atom. The steric number is determined by the sum of bonded atoms and lone pairs around the central atom.
How many molecules are in 19.6 g of NO2?
To determine the number of molecules in 19.6 g of NO2, you first need to calculate the number of moles in the sample. Then, you can use Avogadro's number (6.022 x 10^23 molecules per mole) to convert moles to molecules.
What is th oxidation number for N in NO2?
The oxidation number of N in NO2 is +4. This is because oxygen has an oxidation number of -2, and there are two oxygen atoms in NO2, which gives a total charge of -4. Therefore, the nitrogen atom must have an oxidation number of +4 to balance the charges and make the overall compound neutral.
Which electron-pair geometry corresponds to a steric number of 4?
The electron-pair geometry corresponding to a steric number of 4 is tetrahedral. This means that there are four electron pairs around the central atom, which results in a molecular geometry with bond angles of approximately 109.5 degrees.
What is the oxidation number for NO2?
The oxidation number for NO2 is +4 for the nitrogen atom and -2 for each oxygen atom.
What is the steric number of carbon disulfide?
The steric number of carbon disulfide is 2. This is because carbon has two bonded atoms (sulfur), and there are no lone pairs around the central carbon atom. The steric number is determined by the sum of bonded atoms and lone pairs around the central atom.
What is the steric number of O3?
3 (2 bonding sites & 1 lone pair)
What is the number of lone electron pairs in the NO2- ion?
The NO2- ion has one lone electron pair.
What is steric retardation?
Due to the steric crowding the tetrahedral inter-mediate can't be form and thus esterification can't take place;this is called steric retardation.

How many moles of molecules are in 25.5g of NO2?
To find the number of moles of NO2 in 25.5g, you need to divide the given mass by the molar mass of NO2. The molar mass of NO2 is 46.01 g/mol. Therefore, 25.5g ÷ 46.01 g/mol = approximately 0.554 moles of NO2.
4) How many moles are in 1.18 g of NO2?
To find the number of moles in 1.18 g of NO2, you need to divide the given mass by the molar mass of NO2. The molar mass of NO2 is approximately 46 g/mol. So, 1.18 g / 46 g/mol = roughly 0.026 moles of NO2.
How many moles are in 4.651024 molecules of NO2?
To find the number of moles, divide the number of molecules by Avogadro's number. 4.651024 molecules of NO2 divided by 6.022 x 10^23 molecules/mol equals approximately 7.72 x 10^-24 moles.
How many molecules are in 25.0 g NO2?
To find the number of molecules in 25.0 g of NO2, you can start by converting the mass to moles using the molar mass of NO2. Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
