approximately how much water per day is required to support the lifestyle
of the average U.S. citizen, according to the U.S. Geological survey? -
answer 100 gallons
What is the shape of a water molecule? - answer Bent
Rank the following bonds from the most to least polar, starting with the
most polar bond at the top of the list. - answer H-F, P-O, C-O, C-H
if the sign δ- is used to mark an atom in a covalent bond, it means that
_____. (select all the options that complete the sentence correctly.) -
answer This atom is more electronegative. This atom has a partial
negative. This atom has a higher electron density.
According to the USGS, how much water per day is needed by the average
U.S. citizen? - answer 390L
In a(n) _____ bond electrons are not shared equally, but are closer to the
more electronegative atom. - answer Polar Covalent
, Which of the following is the correct condensed molecular formula for
water? - answer H2O
Which of the following options correctly describe molecular polarity?
Select all that apply. - answer A molecule that contains only nonpolar
bonds is nonpolar.
A molecule that containd polar and nonpolar covalent bonds could be
polar or nonpolar.
Overall molecular polarity depends on the geomerty of a molecule.
Which of the following options correctly describe electronegativity and its
trends? Select all that apply. - answer Electronegativity increases from left
to right.
The element with the highest electronegativity is fluorine.
The higher the electronegativity value of an element, the more strongly it
attracts bonding electrons to itself.
The attraction indicated by the arrow in the illustration is a(n) _____. (the
picture is of two water atoms with the arrow pointing to a red dotted line)
- answer intermolecular force
intermolecular forces - answer attractive forces between molecules
intramolecular forces - answer bonding forces that hold the atoms of a
molecule together
Match each bond with the appropriate difference in electronegativity. -
answer O-H 1.4
F-H 1.9
S-Cl 0.5
Si-F 2.2
