Greetings, zolo:, I can see that you're new, and I'd like to welcome you to the Chemical Forums.  I'd like to remind you to read our Forum Rules{click}.  You agreed to these rules as a condition of signing up for our forum, and they apply to you, whether you agree with them or not, or even if you're unaware of them.  We want to see your work solving this problem.

We're always glad to help someone new to chemistry to learn new things.  But we don't just dump answers to random questions, just to prove how smart we are.  We're also not telepathic, we rely on clear, complete rational observations and facts, to come up with an answer.  We realize there may be a language barrier between us, but we want to work with you to communicate as best we can.

Let's start.

please i need your help ,

Thank you for being polite.  But its not necessary.  We know you cam here for help with your science problem, and we came here to help anyone with science problems.  Unless, you're trying to imply that your problem is more important than any others.  Because that's impolite.

Nothing in science changes one metal into another.  This is basic human logic.  If such a thing were possible, we'd never make anything important out of silver or copper.  We'd use iron, or plastic, to make currency.  Try to keep things like this in mind.

So, something makes a copper coin look silvery.  An impressive trick.

Don't know why you'd assume that.  We assume chemicals are always a little bit hazardous.

You shouldn't do that.

Interesting.  Make a video and post it.

I have a guess.  Here's an old chemistry chestnut:

Warning.  People have been known to use mercuric chloride to do this trick.  Don't get that on your bare skin.
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.
