Atoms are the simpliest form of matter. But an atom can
be classified as an element and an element can be presented various substance. An
element can be oxygen, hydrogen and so on. The combination of two or more
elements is a compound. A compound can be a molecule, same as the atom to
element.
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.
Answer:
The enthalpy of neutralization and its relation to esterification is explained below in details.
Explanation:
The conventional enthalpy variation of neutralization is the enthalpy exchange when extracts of an acid and an alkali respond together under conventional circumstances to generate 1 mole of water. Remark that the enthalpy change of neutralization is always estimated per mole of water produced.
Answer:
It is the second option to stay warm.
Explanation:
Molecular mass of H2O is: 16+2*1=18
so moles of 40g of H2O is: 40/18=2.22
