1. name two metals which are malleable but not ductile.
2. metals behave as reducing agents. why?
3. explain why chlorides of metals conduct electricity while those of
non-metals do not. |

It's their job description. If they were oxidants they would not be
metals.

Since when is NaCl a conductor? Since when is BrCl3 not a conductor?

The answers are surely in your textbook. Finals are coming, and it is a bit late to start
hitting the books. You are doomed to fail. |

Nice one, UA.

I would ordinarily ignore such inquiries, but I am hard put to understand
the difference, if any, between malleability and ductility. I suppose
something like soap, a nonmetal, is malleable even though it would not be
easily drawn into wires.

I can only think of one answer for #1. Then again, I might keep the
air conditioning running harder than some others. But nakul... if you
don't do your homework for real, you might end up in the fiery pits of
hell, and then you'll have lots of choices. |

Do you have a table of metals, with relevant properties?

What is your understanding of a reducing agent?

under what conditions? Normally, neither would be conductive.
What is required for conductivity?

There certainly is lead, or at least fuse, wire. but I think that is
probably made by extrusion rather than drawing.

I am thinking of what kind of metal could be readily formed into sheets but
not drawn into wire. It would be a true metal with low tensile strength.
Rather than answering the question and helping with homework I will say that
it can be a metal obtainable from common table salt. The guy who asked the
question probably will not be able to figure out what that means.

Or maybe, instead, a pipe is just a special case of a thick wire with a
hole drilled through the middle.
