It is for at least 5 hours.
no, gold is the most stable metal that there is.
No, gold does not rot. Gold is a highly stable metal that does not corrode or tarnish in normal environmental conditions.
Nitric Acid cannot react with Gold alone. The only solution that can dissolve Gold is Aqua Regia; a combination of Nitric Acid and Hydrochloric Acid.
GOLD is a metal. At standard temperature and pressure as on Earth, Gold is a very stable unreactive metal. Nuggets of gold are found 'native' , the pure metal. Gold jewelry, whilst a small amount of base metal, does not react with atmosphere. Gold metal can be made to react with 'Aqua Regia'. This is an historical name for a mixture of concentrated sulphuric acid and nitric acid.
if the metal sinks in water is is proof it is gold
No, molten gold is not a solution. A solution is a homogeneous mixture where one substance dissolves in another. Molten gold is a liquid phase of pure gold without any other substances dissolved in it.
Nothing. Gold is a noble metal- it is not displaced by iron.
Gold, as a solid, pure metal, is very stable and will not react with many compounds at all, therefore it will not harm the body if ingested. Ionic forms bound to other derivatives, especially when in solution, may be harmful for the body.
Gold does not dissolve in water, it is inert, so it normally has no pH. However, a sufficiently powerful acid (a mixture of nitric and sulfuric) can dissolve gold, and in that case gold acts as a base, as any metal does.
yes, if the metal is gold it will sink
Gold is a very stable and resistant metal, so it is not easily destroyed by natural elements like air or water. However, gold can be destroyed by strong acids like aqua regia, which can dissolve it. Additionally, extreme heat can melt or vaporize gold.
The people in the world market know; that yellow gold metal, don't has stable market price!
