Following the atomic mass of each of these atoms, we have 1 Fe atom with 56 amu, 3 N atoms with 14 each, and 9 O atoms with atomic mass 16. Adding these together, we get 56 + 42 + 144 = 144 + 98 = 242. Your answer is (4) 242 g/mol
Answer:
HCl, also known as hydrochloric acid, has a covalent bond. The hydrogen (H) atom shares an electron with the chlorine (Cl) to form the bond.
Explanation:
Consequently, the bonding electrons in hydrogen chloride are shared unequally in a polar covalent bond. The molecule is represented by the conventional Lewis structure, even though the shared electron pair is associated to a larger extent with chlorine than with hydrogen.
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-)
