The answer is Potassium Sulfide
Answer:
The correct option is H₂O is an acid and OH⁻ is its conjugate base.
Explanation:
According to the Bronsted-Lowry theory, an acid is a substance capable of yielding a hydrogen ion while a base is a species capable of accepting a hydrogen ion.
A conjugated acid-base pair is a pair of chemical species capable of transforming into each other by exchange of a proton. That is, a conjugated acid is the species that forms after the base accepts a proton. In contrast, a conjugate base is the species that forms after an acid donates its proton.
So, in this case water acts as an acid, yielding a proton to HCO₃⁻, which in turn acts as a base.
<u><em>The correct option is H₂O is an acid and OH⁻ is its conjugate base.</em></u>
Answer:
From left to right C-1 is sp³ hybridized and C-2 is sp hybridized.
Explanation:
Electronic Configuration of C in ground state is...
1s², 2s², 2p²
Electronic Configuration of C in excited state is...
1s², 2s¹, 2px¹, 2py¹, 2pz¹
Hybridization of C in H₃C- ;
In this carbon the four orbitals 2s, 2px, 2py and 2pz with different energies mix together to four equivalent sp³ hybrid orbitals of same energy. Hence this carbon forms four sigma bonds.
Hybridization of C in -CN ;
In this carbon two orbitals 2s and 2p with different energies mix together to form two equivalent sp hybrid orbital of same energy. Hence, this carbon forms two sigma bonds. And the remaining two orbitals form two pi bonds with Nitrogen atom.
