Answer:
0.0315 moles CH₂OH
Explanation:
You can find the amount of moles using the molarity equation. This equation looks like this:
Molarity (M) = moles / volume (L)
Once you convert mL to L (by dividing by 1,000), you can plug the molarity and volume into the equation and isolate to find moles. The final answer should have 3 sig figs because the given value with the lowest amount of sig figs (0.210 M) has this amount.
150.0 mL / 1,000 = 0.1500 L
Molarity = moles / volume
0.210 M = moles / 0.1500 L
(0.210 M x 0.1500 L) = moles
0.0315 = moles
Answer:
HF
Explanation:
This concept can be understood from the knowledge of Intermolecular forces of attraction.
Intermolecular bonds are Van der Waals forces which are weak forces of attraction joining non-polar and polar molecules together. They exist in the form of London Dispersion Forces and Dipole-dipole attraction.
An example of Dipole-dipole attraction is the hydrogen bond which is a unique dipole-dipole attraction between polar molecules in which a hydrogen atom is directly joined to a highly electronegative atom such as fluorine, oxygen, or nitrogen).
Molecules that possess the characteristics of hydrogen bonding have a higher boiling point. In the given question, only HF undergo hydrogen bond due to the electronegative effect of the fluorine element.
F2 occurs as a weak London dispersion force and it occurs between non-polar molecules.

Answer:
False
Explanation:
In chemistry, trigonal planar is a molecular geometry model with one atom at the center and three atoms at the corners of an equilateral triangle, called peripheral atoms, all in one plane. In an ideal trigonal planar species, all three ligands are identical and all bond angles are 120°.
Meaning there shouldn't be any lone pair.
Look up "Structure of a trigonal planar molecule" for a visual
So it is false.
