do lead and gold bond when placed together for a time?

I do not think that atoms will fly over the gap between a piece of gold and and old lead pipe.\n\nHowever, gold and lead readily form a wide range of alloy compositions. Lead has a high affinity for gold and can be used as a collector for gold in pyrometallurgical processes. The lead can be subsequently separated by volatilization.

If the metal not in the compound is higher on the activity series than the metal in the compound then a reaction will occur and the metals will switch spots. If the metal not in the compound isn't higher on the activity series than the metal in the compound then no reaction will take place. You got to be joking if you think I'm going to be doing 20 problems for you. The only way to learn these is to do them on your own. Just so you know in #6 a reaction will not occur.\n\nHere is an activity series:\nhttp://en.wikipedia.org/wiki/Reactivity_series\n\nREACH doesn't know how to do these, don't listen to his answer.

well it depends, but generally they don't stay that way for long. They react with other atoms that are charged opposite of whatever they are. This is how chemical bonds are formed. It can either be a covalent bond in which they atoms are "sharing" electrons in order for both to be neutrally charged or they form an Ionic bond.

You should recognize that, when they combine with nonmetals, metals tend to LOSE electrons and form POSITIVE ions. Nonmetals, on the other hand, tend to GAIN electrons and form NEGATIVE ions.\n\nGet an "A".

Could you use lead solder?

If I've understood what you're asking then:\nA\nCd(s) + Ag2+ -> Cd2+ + Ag(s) \n\nCadmium occurs at Anode and the Silver would deposit on the Cathode\n\nB (I hate Manganese equations and the partial above is incorrect)\n\nMnO2 + 4H+ + 2AgBr -> Mn2+ 2Br- + 2Ag + 2H2O\n\nMnO2 @ Anode\nAgBr @ Cathode\n\nC\n\n(PtCl4)2- + 4Ag -> Pt + 4AgCl \nAg @ anode\n(PtCl4)2- @ Cathode

yes gold is based on a 24 part scale for example when u have 14 kt gold u have 14 parts gold and 10 parts other material generally your gold vendors use nickel in white gold and for yellow gold generally copper zinc or sometimes a palladium so anything under 24kt gold is mixed with other material in one hand to cut the gold and in the other to make the gold stronger due to the malluability of gold.

It all depends on what the incomer is made from, Metal, PVC?\n\nI take it the incoming pipe is metal? If so the rule is, if you can stand and touch that pipe and other pipes at the same time, you should cross bond between them. The reason for cross bonding is so as not to have a difference in potential between the pipes if an electrical fault occurs, if 1 pipe is earthed and one isn't and you touch both pipes you will get a shock if both are bonded you will not get a shock.\n\nIf in doubt cross bond them, always better to be safe than sorry!

Gold is very nonreactive.  It will not dissolve once in your mouth (unlike the mercury compounds used in other dental work).  If it does not dissolve, it cannot poison you.

yes, they always covalently bond with each other under any normal type conditions\n\neven if you were to conveniently have an oxygen cation and anion that you combined, they would lose their ionic nature and bind in a covalent fashion

Pure Gold is an element, Au.\n\nHowever, the gold you get from shops are not pure gold, but are alloys with other compound, since pure gold is soft at room temperature.

NaCl, the bonding is stronger

Actually, we can.\nIf you put lead into an "atom smasher" you can synthesize gold.\nThe problem is that the process costs more than the price of gold.

Gold is not very reactive because its unpaired 6s electron is at a lower energy level than its many paired 5p and 5d electrons.  So even though gold would like to give up its unpaired electron or accept a partner for it, it usually can't because of the stability of the higher energy electrons that are already paired.

it would be Covalentic ofcourse...\n\nIonic is usually when  Metal is reacting with non metal...\n\nin this case , both are not metals so it would be covalentic

I'd like to encourage you to learn chemisrty instead. The alchemists tried and tried to make lead into gold and similar things. Now we know that it cannot be done. They wasted their time. Don't waste yours. Learn and make something of yourself.

The process of recovering gold from electronics circuits is relatively simple, but also quite expensive to set up.\n\nEquipment required includes a DC power source capable of delivering several amperes of current at approximately 12 to 100 VDC.  ( A DC Arc Welding Power supply will work well here. )\n\nThen the material containing the gold to be extracted must be crushed.  Crushing multi-layer fiberglass circuit boards is difficult, but it must be done to expose as much of the gold as possible.\n\nA solution of water and some Gold Salt should be mixed.  Gold Sulfate is probably the cheapest, but it is STILL very expensive.  The solution should be in the range of 0.5 gram per litre.\n\nObtain a tank or container made of conductive metal.  Copper is best.  Place the crushed material in the tank,\nPour in the Gold Salt solution until crushed material is completely covered. Attach the POSITIVE anode of the power supply to the tank.  Attach the NEGATIVE cathode of the powersupply to a small piece of gold wire or gold goin or jewelry ( Just a seed to get the thing started . ) And immerse this negative lead in the solution, being careful NOT to let it touch the tank or the crushed material.\n\nTurn on the power...And walk way...The Gold from the crushed material will be 'deposited' on the Cathode gradually over time.  The more current you are able to safely supply without burning something up, the faster the process will be.
