Answer:
a. CH4 is only held together by London dispersion forces since any dipoles cancel out due to symmetry. On the other hand H2O has strong hydrogen bonds
b. PH3 has dipole-dipole forces while NH3 is held together by stronger hydrogen bonding
c. C2H6 and C3H8
. Both substances are held together by London dispersion forces since any dipoles cancel out due to symmetry. However C3H8 has the stronger London dispersion forces of the two because it is a larger molecule,
d. BH3 is held together by London dispersion forces since any dipoles cancel out due to symmetry while OF2 is held together by stronger dipole-dipole forces
Explanation:
The periodic table of elements has a rich diverse number of elements. Every element on the table is arranged based on their atomic numbers into their respective groups and columns.
The coining of words from the table is done creatively by combining symbols of elements.
Here are some of the world list:
TaXEs , TeAcH ,TeAm , TeTaNUS , CoW,, CoVEr COY

Answer:
Ocean currents bring warm water from the equator and cold water from the poles *
Explanation:
More sun shines on the water near the equator than the water near the poles because of earth's axis. So warmer water comes from the equator and colder water comes from the poles.
The answer is physical as neither component changes chemically.
