Solid NaCl:

  • Ionic bonds.

Solid H₂O:

  • Hydrogen bonds, and
  • Dipole-dipole interactions.
<h3>Explanation</h3>

NaCl is an ionic compound. It contains myriads of Na⁺ ions and Cl⁻. The two types of ions carry opposite charges. They attract each other via electrostatic forces. This type of electrostatic force is known as ionic bonds. Those bonds hold the ions in a gigantic ionic lattice.

H₂O is a covalent compound. Two H atoms are bonded to one O atom in each molecule. The O-H single bond is <em>highly polar</em>. Also, there are two lone pairs of electrons on the central O atom in each molecule. The O-H bond is so polar that the H atom carries a very strong partial positive charge. The H atom would be attracted to lone pairs on the O atom in neighboring H₂O molecules. Hydrogen bonds between the H₂O molecules hold them in place in their solid state.

There are two O-H single bonds in each H₂O molecule. H₂O molecules are V-shaped due to the presence of the two lone pairs on the central oxygen. Dipoles due to each O-H bonds do not line up within the molecule. As a result, H₂O molecules carry <em>non-zero net dipole</em>. They would attract each other by dipole-dipole interactions. That intermolecular force coexists with hydrogen bonds. It adds to the strength of the attractions between H₂O molecules.

Waves transport water in the deep ocean toward the coastlines. True or false
ASHA 777 [7]

Answer:

Most likely true

Explanation:

because the speed of all ocean waves is controlled by gravity, wavelength, and water depth. ... Waves moving through water deeper than half their wavelength are known as deep-water waves. On the other hand, the orbits of water molecules in waves moving through shallow water are flattened by the proximity of the sea surface bottom.

5) O etanol C2H6O, combustível produzido em grande escala no Brasil, pode ser obtido pela fermentação da sacarose C12H22O11 enco
UNO [17]

Answer:

a) 0.15

Explanation:

A concentração de sacarose é 0,15 g / l no etanol. O Brasil está produzindo etanol em grandes quantidades que é usado como combustível em veículos e indústrias. Este etanol é produzido a partir da cultura da cana-de-açúcar e o Brasil é o segundo maior produtor mundial com cerca de 34,45 bilhões de litros em 2019. Os Estados Unidos da América e o Brasil produzem cerca de 84% do etanol mundial.

How many moles of kf are contained in 244 ml of 0.135 m kf solution? the density of the solution is 1.22 g/ml?
galben [10]
The Molarity of a solution = number of moles / volume.  
Volume = 244ml = 0.244L
 So it follows that number of moles = Molarity * volume 
 Number of moles = 0.135 * 0.244 = 0.03945.
 Hence the number of moles = 0.03945

The equilibrium constant for the reaction: HCHO(g) ⇌ H2(g) + CO(g).
tiny-mole [99]

Answer:

K = [H2] [CO] / [HCHO]

Explanation:

HCHO(g) ⇌ H2(g) + CO(g)

We can obtain the expression for the equilibrium constant for the above equation as follow:

Equilibrium constant, K for a given reaction is the ratio of the concentration of the product raised to their coefficient to the concentration of the reactant raised to their coefficient.

Thus, the equilibrium constant, K for the above equation can be written as follow:

K = [H2] [CO] / [HCHO]
