Of the following solutions, which has the greatest buffering capacity? A) 0.121 M HF and 0.667 M NaF B) 0.821 M HF and 0.217 M NaF C) 0.821 M HF and 0.909 M NaF D) 0.100 M HF and 0.217 M NaF E) They are all buffer solutions and would all have the same capacity

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

explanation:

2b2t

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
