No. hydrogen will eliminate only copper, or gold in the oxidized state, and when
dissolved. On 2nd thought, yes. Bring copper and gold into the oxidized, dissolved states, using aquq regia, a solution of 3 parts HCl with 1 part HNO3. Replace spare HNO3 with HCl, using 3 circles of HCl addition and vaporizing.
Bubbling hydrogen at this point will free gold and leave copper dissolved

What metals are not silver gray in color?
Copper and gold.
What removes copper from gold?
That's an easy one, nitric acid will do that, also hydrochloric acid + hydrogen peroxide, A/P
Why copper is not used to prepare hydrogen in the laboratory?
copper doesn't displace hydrogen from acids
What is the formula for copper oxide and hydrogen sulphate?
copper oxide- CuO hydrogen sulphate- h2SO4
What metals cannot displace hydrogen gas from a dilute acid?
all those metals which are present below Hydrogen in the reactivity series like Ag , Cu , Au , Pt ,etc. ^^ He is incorrect. All metals, one or another, will react with some acids to produce Hydrogen Gas. -He mentioned Copper and Silver. Silver and Copper will react with Nitric Acid giving off Hydrogen and NitroDioxide Gas. He mentioned Gold and Platinum. Gold and Platinum will react with Aqua Regia (A mixture of Hydrogen Chloride and Nitric Acid) giving off Nitric Oxide, Nitrogen Dioxide, and Hydrogen gas. All metals will react with FluoroAntimonic Acid, Xenic Acid, or any other super acid to give off hydrogen gas and other gases as well.
Process for seprating gold and copper?
the copper dissolves in some acids, as nitric and a mixture of hydrochloric with hydrogen peroxide, while gold does not
Can anyone explain the science behind copper into gold or show a website that tells the explanation?
Copper into gold, means putting copper powder in gold salt solution. Because copper is closer to hydrogen then gold, in the electromotive scale, it will dissolve, freeing the gold
What metals are not silver gray in color?
Copper and gold.
What was the elements?
Copper. More probably Gold, it doesn't corrode. If your asking cosmological not technological, it is definitely Hydrogen.
What is mixture elements?
Your question is not clear: probable you think to alloys (gold-copper), mixtures of gases (hydrogen-nitrogen) etc.

What is the formula for copper oxide and hydrogen sulphate?
copper oxide- CuO hydrogen sulphate- h2SO4
What is the colour change when copper oxide is added to hydrogen?
Copper oxide is black and when reacted with Hydrogen is REDUCED to elemental copper which is "copper" colored or red-brown

Can copper be used to prepare hydrogen by reaction with diluteacids?
No. Copper is below hydrogen in the electromotive series and therefore can not displace hydrogen from its compounds.
Does copper look like gold?
Copper and gold look similar, but while gold is yellowish, copper is reddish.
