Answer:
dipole-dipole forces, ion-dipole forces, higher molar mass, hydrogen bonding, stronger intermolecular forces
Explanation:
<em>1. H₂S and H₂Se exhibit the following intermolecular forces: </em><em>dipole-dipole forces </em><em>and </em><em>ion-dipole forces</em><em>.</em> These molecules have a bent geometry, thus, a dipolar moment which makes them dipoles. When they are in the aqueous form they are weak electrolytes whose ions interact with the water dipoles
<em>2. Therefore, when comparing H₂S and H₂Se the one with a </em><em>higher molar mass</em><em> has a higher boiling point.</em> In this case, H₂Se has a higher boiling point than H₂S due to its higher molar mass.
<em>3. The strongest intermolecular force exhibited by H₂O is </em><em>hydrogen bonding</em><em>. </em>This is a specially strong dipole-dipole interaction in which the positive density charge on the hydrogens is attracted to the negative density charge on the oxygen.
<em>4. Therefore, when comparing H₂Se and H₂O the one with </em><em>stronger intermolecular forces</em><em> has a higher boiling point. </em>That's why the boiling point of H₂O is much higher than the boiling point of H₂Se.
Answer:

If we are talking about common chemical sanitizers, then those include C. Iodine, Chlorine, and Quat ammonium.
It is very important to sanitize and keep everything clean, and these will help you a lot.
<h2>Answer:</h2>
The correct answer is option D which is substances will pass in and out of the cell in an uncontrolled manner.
<h3>Explanation:</h3>
- Cell membrane is outer organelle in the cell, it is responsible for the transport of materials into and out to the cell through osmosis and active transport.
- In the absence of the cell membrane, there will not be control of transport of a materials to the cell.
- Energy production is the task of mitochondria and food storage is the function of vacuoles.
- Photosynthesis takes place on the chloroplasts.
Answer is: the
molar mass of unknown molecular compound is 245.67 g/mol.
<span>m(compound) = 5.65 g.
m(benzene) = 110 g ÷ 1000 g/kg = 0.11 kg.
ΔT = 5.45°C - 4.39°C.</span>
ΔT = 1.06°C.
Kf(benzene) = 5.07°C/m.
<span>M(compound) = Kf
· m(compound) / m(benzene) · ΔT.
M(compound)= 5.07°C/m · 5.65 g / (0.11 kg · 1.06°C).
M(compound) = 245.67 </span>g/mol.
