Aromatic compound has continuous cyclic structure with( 4n+2)π electrons (Huckels rule), where n = 0,1,2…
Here number of pi electron are 6, where 4 from two double bond and 2 from nitrogen non-bonding electrons, hence it has total 6 pi electrons, therefore
6= ( 4n+2)π
4 = 4n
n =1
Hence it is an aromatic compound
Displacement, usually the method that is used to measure the volume of an irregularly shaped object.
Answer: Arsenic has five valence electrons.
Explanation: Good luck!
1. Determine if the ionic substances can break apart into ions.
- e.g. CaCO3 isn't very soluble, do it can't dissolve and dissociate. If it can't pop apart, no ions.
2. Swap the partners for all the other ions that you can get from step 1. You can skip pairings with the same charge - a + can't get close to another + to react.
3. Use solubility, acid/base, and redox rules to see if anything will happen with the ions in solution.<span />
Answer:
wave velocity= frequency × wave length
=1×3
=3m/s
Explanation:
The distance covered by the wave in one second is equal to its wavelength, therefore,
wave velocity=wavelength/time period
OR wave velocity= frequency× wavelength
You can assume velocity as speed here.
