What evidence indicates that there is a reaction between gold and aqua regia?
The solution will heat up.
Aqua regia is the reaction endo or exo?
The reaction of aqua regia is exothermic because it releases heat when the acids interact with metals, causing a very strong and aggressive reaction that can dissolve gold and platinum.
How do you destroy gold?
You can't, all the gold that has ever been mined or extracted from the earth still exists today. It does not tarnish, it does not rust. Gold may be dissolved in aqua regia (1 part HNO3 + 3 parts HCl) or in potassium cyanide + potassium (sodium) hydroxide solutions.
What can destroy gold?
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.
What can dissolve platinum?
Aqua Regia (HCL+Nitirc acid) Pt+4HNO3+6HCl=H2PtCl6+4NO2+4H2O heat is necessary
How can you neutralize an aqua-regia solution using sodium hydroxide solution?
First dilute A.R. by pooring it SLOWLY into a large amount (10-fold) of (cold) water while mixing, and then (SO AFTER dilution) the same (molar) amount of NaOH (diluted) can be poored into it in the same way. This careful procedure is required because of high reaction heat and aggressive chemicals and toxic fumes might escape when not done carefully.
What is an Aqua-K pad?
Aqua K pad is a heated water filled pad that is used for moist heat,for a large area of the body

What does refining oil mean?
refinin oil means to heat the oil to separate it into chemicals
Do gold teeth conduct heat?
Yes, gold and gold alloys are good conductors of heat and electricity.
Is gold a conducter an insulater of heat?
Metals are conductors of heat. Gold is a metal.
How much heat is needed to heat gold?
That depends on the amount of gold, and on how much you want to heat it. You have to multiply the amount, the temperature difference, and the specific heat of gold - of course, using compatible units.That depends on the amount of gold, and on how much you want to heat it.
