Question

How many of these molecules are polar? H2O, BeH2, H2, H2S Select the correct answer below: 0 1 2 3 A drop of water spreads out on a glass surface. What is true about this observation? Select the correct answer below: The cohesive forces are stronger than the adhesive forces. The adhesive forces are stronger than the cohesive forces. The covalent bonds in the water are strong and there are zero intermolecular forces. The adhesive forces are strong enough to break the water molecules into ions. When a 210 mL sample of water at 10°C was exposed to an atmosphere containing a gaseous solute at 16.66 kPa, the result was the dissolution of 4.82×10^-3 g of the solute. Use Henry's law to determine the solubility of this gaseous solute when its pressure is 74.91 kPa. Your answer should include two significant figures. Provide your answer below:

about this observation?
Select the correct answer below:
The cohesive forces are stronger than the adhesive forces.
The adhesive forces are stronger than the cohesive forces.
The covalent bonds in the water are strong and there are zero
intermolecular forces.
The adhesive forces are strong enough to break the water
molecules into ions.
