Atmospheric pressure decreases as altitude increases. In other words, there is more air pushing down on you at sea level, and there is less air pressure pushing down on you when you are on a mountain.

If hexane C6H14, octane C8H18, and octanol C8H17OH are heated evenly at different altitudes, rank them according to the order in which you would expect them to begin boiling.

A) Hexane at high altitude
B) Octane at high altitude
C) Octane at sea level
D) Octanol at sea level

some sources quote the lethal dose, for an average 170lbs opiate-naive individual is between 75 and 375 mg

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
