How many moles of nacl could be made by combining 20,000 moles of na with 2 moles of ci? a 20,000 moles naci 2 moles naci b. 1 mole nacl none of the above select the best answer from the choices provided a b c d

None of the above.

Explanation:

The limiting factor of this  is the chlorine. You only have 2 moles of chlorine.

2Na + Cl_2 ==> 2*NaCl

The equation tells you that for every mol of Cl2 that you have, you require 2 moles of Na and you get 2 moles of NaCl

So what that means is that if you have 2 mols of Cl2, you need just 4 moles of Na, and you will get 4 mols of NaCl

Since 4 is not one of your choices, the answer is none of the above

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.
