Answer:
water
Acidity and basicity are usually determined in a solvent. The strongest acid in the solvent is always the conjugate acid of the solvent and the strongest base is the conjugate base of the solvent. So, in water, the strongest acid is H3O+ and the strongest base is OH- (conjugate base of water).
Answer:
Chemical energy is energy stored in the structure of molecules within the bonds between atoms. Energy can be added or released from a molecule by changing the arrangement of electrons (rearranging chemical bonds).
Explanation:
<span>It exhibits the Tyndall effect. ---> FALSE. IT BELONGS TO THE COLLOIDES.
Brownian motion is not visible in it.--> FALSE. IT IS A PROPERTY OF FLUIDS WHEN MICROSCOPICAL PARTICLES ARE IN IT.
It cannot be separated using filtration.--->TRUE. THE PARTICLES CANNOT BE DISTINGUISHED NOR SEPARATED BY FILTRATION.
It has at least two phases.-->FALSE. E.G. SALT IN WATER FORM ONE UNIQUE PHASE.</span>
Answer:
The correct answer is option C.
Explanation:
Isoelectronic species are those atoms or ions which same number of electrons.But they differ in physical and chemical properties.
Atomic number of nitrogen atom is 7.
![[N]=1s^22s^22p^3](https://tex.z-dn.net/?f=%5BN%5D%3D1s%5E22s%5E22p%5E3)
![[N]^{3-}=1s^22s^22p^6](https://tex.z-dn.net/?f=%5BN%5D%5E%7B3-%7D%3D1s%5E22s%5E22p%5E6)
Number electron in nitride ions = 
Atomic number of oxygen atom is 8.
![[O]=1s^22s^22p^4](https://tex.z-dn.net/?f=%5BO%5D%3D1s%5E22s%5E22p%5E4)
![[O]^{2-}=1s^22s^22p^6](https://tex.z-dn.net/?f=%5BO%5D%5E%7B2-%7D%3D1s%5E22s%5E22p%5E6)
Number electron in oxide ions = 
![[Ne]=1s^22s^22p^6](https://tex.z-dn.net/?f=%5BNe%5D%3D1s%5E22s%5E22p%5E6)
Number of electrons neon = 
Hence, 
are isoelectronic.
