The correct answer is Urea
MgSO4 + 2NaOH —> Mg(OH)2 + Na2SO4
Answer:
(δ+) C → O (δ-)
(δ-) O ← Cl (δ+)
(δ+) O → F (δ-)
(δ+) C → N (δ-)
(δ-) Cl ← C (δ+)
(δ-) S ← H (δ+)
(δ+) S → Cl (δ-)
Explanation:
The polarity of a bond depends on the difference of electronegativity (EN) between the atoms that form it. The dipole moment (μ) points to the atom with the highest electronegativity, which is the one with a negative charge density (δ-), while the other atom has a positive charge density (δ+).
<em>The first bond is between C and O. </em>
EN(C) = 2.5; EN (O) = 3.5
(δ+) C → O (δ-)
<em>The second bond is between O and Cl. </em>
EN(O) = 3.5 ; EN(Cl) = 3.0
(δ-) O ← Cl (δ+)
<em>The third bond is between O and F. </em>
EN(O) = 3.5; EN(F) = 4.0
(δ+) O → F (δ-)
<em>The fourth bond is between C and N. </em>
EN(C) = 2.5; EN(N) = 3.0
(δ+) C → N (δ-)
<em>The fifth bond is between Cl and C. </em>
EN(Cl) = 3.0; EN(C) = 2.5
(δ-) Cl ← C (δ+)
<em>The sixth bond is between S and H. </em>
EN(S) = 2.5; EN(H) = 2.1
(δ-) S ← H (δ+)
<em>The seventh bond is between S and Cl.</em>
EN(S) = 2.5; EN(Cl) = 3.0
(δ+) S → Cl (δ-)
Mass = no. of moles x molecular weight
m = n x Mr
m = 2.5 mol x (24 + [16 x 2])
m = 140g
There are two subshells that are s and p, which are present in the second energy level.
The energy level can be defined as the fixed distances from the nucleus of an atom where electrons may be found. Each energy level is divided into some Subshells. These subshells are known as s-subshell, p-subshell, d-subshell, and f-subshell. This subshell contains some orbitals, these orbitals are the place where there is the maximum probability of getting the electrons. In one orbital, a maximum of two electrons can be present.
Hence, there are two subshells in the second energy level.
