Answer 1

Pb lead

look it up on a table

metals

metal

chemfinder.com will tell you

Lead is found in mines. It is extracted by mining.

The lead chamber process was formerly used to make sulfuric acid. Lead is also used for fishing weights. It was formerly used in paints. However, since it is toxic, it is avoided in a lot of applications.

Answer 2

Lead is a steel who's use by ability of guy dates lower back previous to any written historical past. by using fact lead ores have a number of maximum RDs (relative density) of any mineral, they are able to be easily remoted purely like gold is with any style of gravity sorting gadget (ie a gold pan or a sluice container). blended with its incredibly low melting element (you could smelt some ores in a warm campfire), guy discovered very early on the thank you to pay interest lead for his use. As to who replaced into ultimately waiting to appreciate the easy nature of lead, i might say you will possibly might desire to ask a chemist. guy went for hundreds of years believing lead replaced into basically some sort of polluted gold ore and that they stepped forward an entire commerce referred to as alchemy to purpose and choose the thank you to transform the stuff. over the years they figured it out it wasn't going to take place yet interior the technique gave start to incredibly some cutting-factor chemistry and metalurgy. optimistically that replaced into the respond you have been searching for.

Answer 3

Do you want me to carry you to school on my back as well? Might as well, I'll have done everything else!

If you want to get some help with homework (or whatever) thats fine....but don't expect us to do ALL the work for you.

It would be a waste of typing to reproduce all this information when it's so easily found here: http://en.wikipedia.org/wiki/Lead

Answer 5

I realize that you said "no links", but this site has everything you need. It's much more efficient for you to read it yourself than it is for me to read it and type it. Not my homework, anyway. And you'll learn it better reading it yourself. But that's just the teacher in me.
