Can Someone Help Me With This Please?

Explanation:

This is going to be a very d-u-m-b question, but when you touch the Mg rod, why doesn't it kill you? After all, it is giving away a lot of electrons, isn't it?

The reason it doesn't kill you is because after the electrons are given away, they go into the liquid on the left side.

The important equation for this part of the reaction is

Mg ==> Mg2+ + 2e-

So the Mg goes from a solid to an ion (Mg2+) which goes into the liquid on the left.

The Mg must loose weight

i think it's c. i'm not sure but i think so.
