This problem is asking for the intermolecular forces in ethanamine, C₂H₅NH₂. Hence, after analyzing it, we find they are both London dispersion forces and hydrogen bonding.
<h3>Intermolecular forces</h3>
In chemistry, intermolecular forces are the responsible of holding molecules together both in liquids and solids, and they depend on the type of bonds exhibited by the molecule. In this case, ethanamine:
Has C-C, C-H, C-N and N-H bonds. Now, C-C, C-H and N-H are strongly nonpolar as they have an electronegativity difference below 0.7, which means ethanamine has London dispersion forces as the weakest ones.
In addition, the presence of N-H bonds, provides this molecule with stronger intermolecular forces, hydrogen bonding, which occur in N-H and O-H bonds.

Answer:
M KIO3 = 1.254 mol/L
Explanation:
∴ w KIO3 = 553 g
∴ mm KIO3 = 214.001 g/mol
∴ volumen sln = 2.10 L
⇒ mol KIO3 = (553 g)×(mol/210.001 g) = 2.633 mol
⇒ M KIO3 = (2.633 mol KIO3 / (2.10 L sln)
⇒ M KIO3 = 1.254 mol/L
Answer:
BIPHASIC LIQUIDS are used ear cleaning, to softening the wax so that mild infections can be treated.
Explanation:
BIPHASIC LIQUIDS are liquids that contain two immiscible phases, one is suspension and the other is emulsion. In suspension, the finely solid are dispersed in a liquid or semi solidwhich is use for medicament
The emulsion consist of immiscible liquids, one is dispersed in globules.
They are used ear cleaning, to softening the wax so that mild infections can be treated.
The first blank is splitting because water is made up of hydrogen and I think oxygen molecules. The second blank is I think fuel because there are cars that run on hydrogen.
Density = Mass / Volume
Mass = Density * Volume
Mass = 2.7 * (4*4*4)
Mass = 2.7 * 64
Mass = 172.8 grams
