Answer:
If a solid line represents a covalent bond and a dotted line represents intermolecular attraction, which of the choices shows a hydrogen bond?
-N-------H-O-
-O------H-C-
-C-----H-F-
H-H
Of the options shown those that form hydrogen bonds are the following:
-N-------H-O-
-O------H-C-
Since they occur from the attraction in a hydrogen atom and an oxygen or nitrogen atom with a negative charge.
Explanation:
The hydrogen bridge or hydrogen bond force is the attractive electrostatic force between an electronegative atom and a hydrogen atom covalently bonded to another electronegative atom. It results from the formation of a charge-dipole force with a hydrogen atom attached to a nitrogen, oxygen or fluorine atom.
The hydrogen bond strength is located somewhere between a covalent bond and a Van der Waals force (dispersion force). This type of bonding occurs both in inorganic molecules such as water, and in organic molecules such as DNA.

Answer:
The concentration of chloride ion is 2.887 M.
Explanation:
Here we have a combination BaCl₂ and AlCl₃
1 mole BaCl₂ can produce 2 moles chloride ions as follows;
BaCl₂ → Ba²⁺ + 2Cl⁻
Therefore;
0.554 mole BaCl₂ can produce 2×0.554 moles chloride ions;
1 mole AlCl₃ can produce 3 moles chloride ions as follows;
AlCl₃ → Al³⁺ + 3Cl⁻
Therefore;
0.593 mole AlCl₃ can produce 3×0.593 moles chloride ions
Total concentration of chloride ions = 2×0.554 + 3×0.593 = 2.887 moles of Cl⁻ in 2×16.8 ml solution
The concentration of Cl⁻ is 2.887 M
