Nothing. The gold remains the same.
At room temperatures and pressures gold is extremely resistant to chemical reactions with oxygen and/or water.
It is slightly soluble in water, but not so much that you'd notice. There are a few grams of gold dissolved in every million tons of seawater - its really not economical to extract.
At very very high temparatures and pressures, such as are found thousands of metres underground, gold is slightly more soluble in water and thus is able to very slowly accumulate in quartz veins - which is the 'natural' form when veins of gold are discovered.
it burns i think
nothing. gold doesn't react with water
Nothing; gold is not soluble in water. The colloidal gold is a more complicate problem.
It usually sinks, but always gets wet.
Rust is the common name of the corrosion products of Iron. These are the results of the reaction of iron with water and oxygen. Rust is also the term used only for iron oxides (Iron which reacts with oxygen). For corrosion of gold, see related link below. == ==
it burns i think
You mean Is Steel, Water, Oxygen, and gold which one is a component well. The only that is a mixture is water.
(most dense to least dense) gold, mercury, water, oxygen
nothing. gold doesn't react with water
According to the textbooks, nothing.Gold is very inert, and wont even react with dilute acids.
Nothing; gold is not soluble in water. The colloidal gold is a more complicate problem.
Oxygen is a gas at room temperature. Gold is a solid, water is a liquid, and lightning is an electrical discharge.
if the metal sinks in water is is proof it is gold
i think it is gold
Gold is said to be noble metal because it is unreactive and does not react with either oxygen or water.
The gold will sink, nothing more. It will not dissolve or react in any way.
Yes, gold can react with oxygen to form gold oxide.
