How can one determine the orbital hybridization of an atom in a molecule?
To determine the orbital hybridization of an atom in a molecule, you can look at the atom's steric number, which is the sum of the number of bonded atoms and lone pairs around the atom. The hybridization is determined by the steric number according to the following guidelines: Steric number 2: sp hybridization Steric number 3: sp2 hybridization Steric number 4: sp3 hybridization Steric number 5: sp3d hybridization Steric number 6: sp3d2 hybridization By identifying the steric number, you can determine the orbital hybridization of the atom in the molecule.
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.
What is the oxidation number for NO2?
N is +3, O is -2. The anion has an oxidation number of -1 (equal to its charge)

What is the number of lone electron pairs in the NO2- ion?
The NO2- ion has one lone electron pair.
What is the steric number of O3?
3 (2 bonding sites & 1 lone pair)

How many moles of molecules are in 25.5g of NO2?
Determine the molar mass of NO2 using the subscripts in the formula and the atomic weights in grams from the periodic table. 1 mole NO2 = (1 x 14.0067g N) + (2 x 15.9994g O) = 46.0055g NO2 Calculate the moles NO2 by dividing the given mass by the molar mass. 25.5g NO2 x (1mol NO2/46.0055g NO2) = 0.554mol NO2
What is the oxidation number for NO2?
N is +3, O is -2. The anion has an oxidation number of -1 (equal to its charge)
What are the oxidation numbers of nitrogen in NH4, NO2, and NaNO3?
The oxidation number of nitrogen in NH4 is -3, in NO2 is 3, and in NaNO3 is 5.
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?
4.651024 molecules of NO2 equals 7,721 moles.
Which electron-pair geometry corresponds to a steric number of 4?
steric number of an atom(for example the N of NH4) within a compound is calculated by adding up the number of atoms bonded to that atom(H's bonded to the N) plus the number of lone electron pairs (in this case none, because N's 2p shell is now full, rendering it a stable molecule). This gives NH4 a steric number of four. The positive charge comes from the additonal H+
