Why are the bond lengths in no3- all identical and shorter than a nitrogen-oxygen single bond?

NO3- has three resonance structure. One double bond between N and O and another two N - O single bond. Since the double bond can be formed between N and any other O it is said that it has a resonance structure. This means that the true structure of NO3- is not any of this structure, but rather a hybrid of all three. Hence all 3 bond lengths would be identical AND shorter than single bond as it is basically an average between single and double bond. It is of course longer than a double bond

∙ 10y agoThere is a double bond character between N-O bond due to resonance but no such character in N-OH because no pi bond between N and OH.. The bond length of NO is lesser than NOH (as double bond is shorter than single boñd)

Which is longer carbon-carbon single or double bond?
double bonds are shorter because they are stronger so they pull the carbons closer together
What proof has led researchers to conclude that the earth once contained a single continent?
there are many identical species of fish in different freshwater lakes around the world.
Process by which a cell divides into two daughter cells?
Identical twins are produced when a single fertilized egg splits into two halves that grow separately. Non-identical twins happen when their mother releases two eggs together, and both get fertilized.
Why all carbon-carbon bond lengths in benzene are equal?
This is due to the resonation process that gives the allusion of all bond lengths being equal. In fact the bonds are in a state of constant flux and 'blend' into one. It is much like the apperance of a helicopters rotar blades i.e. in flight it appears as a blurr but whilst stationary it is clear that there are simply two blades -------------- The paragraph above is incorrect. Forget the fan blade and helicopter rotor analogies for resonance. There is NO evidence that bonds are jumping back and forth between a single bond and a double bond. That's just wrong. Resonance structures are simply an attempt at representing with Lewis structures something which really can't be represented with Lewis structures, that of a "partial" double bond. In carbonate ion, all of the carbon-oxygen bonds are identical, and have a length somewhere between that of a single bond and a double bond. The bond order for the carbon-oxygen bond in carbonate is 1.33. The partial double bond comes from delocalized pi bonding. In addition to the single bond between the central carbon and each oxygen, there is a delocalized pi bond between the central carbon and each of the oxygen atoms. There is overlap of the p-orbital on C with each of the p-orbitals on the oxygen atoms, but there are not enough electrons for three double bonds. It is this additional pi bonding which makes each of the carbon-oxygen bonds have a bond order of 1.33, and a bond length and bond strength between those of single and double carbon-oxygen bonds. ----- Pisgahchemist
What is a single compound?
A single compound is one compound
What is The scientific name for identical twins.?
Identical twins (monozygotic) occur when a single egg, fertilized by a single sperm, splits into two identical halves. Two separate babies with identical DNA are formed. Identical twins are always the same sex and blood type. http://www.twin-pregnancy-and-beyond.com/identical-twins-or-fraternal-twins.html
How do you obtain identical copies of a single cell?
By cloning them
Why are identical twins identical and fraternal twins are not?
Identical twins are formed from a single egg that splits into two. Fraternal twins are formed from two separate eggs that are both separately fertilized. So identical twins have identical DNA, and fraternal twins do not.
Identical twins happen when the two eggs are fertilised?
No. They have to come from the same egg and sperm to have the same DNA (and be identical). Fraternal twins are non identical twins and come from two separate eggs.
Why must any differences between identical twins be controlled only by the environment?
Identical twins have the same DNA - meaning that without the effects of environment they would be identical in every single way.
What is the process of creating a opoulation of genetically identical cells from a single cell?
Cloning
What results when a single bacterium reproduces?
Two genetically identical daughter cells
What is an elementary particle that is identical with the nucleus of the hydrogen atom?
A single proton
A sentence for identical twins?
Identical twins develop from a single egg that splits into two.Identical twins can be so similar that their parents cannot tell them apart.
Why are identical twins and fraternal twins not the exact same?
Identical twins are formed from a single egg that splits into two. Fraternal twins are formed from two separate eggs that are both separately fertilized. So identical twins have identical DNA, and fraternal twins do not.
How are identities made?
A monozygotic triple pregnancy is event in which identical triplets are conceived. This occurs when a single fertilized egg slits to form three identical babies.
What is a reproduction in which a single parent produces offspring's that are identical to the parent?
This is called "asexual reproduction".
