Because Gold is an extremely unreactive metal, which means that it is not found in any compounds, e.g. Gold Oxide, but is only found on its own. So no chemical reaction is needed to obtain gold.
Also, if you look at a metal reactivity series, gold will be at the bottom of the list.

Energy is the energy needed to start a chemical reaction?
The energy needed to statr a chemical reaction is the 'Activation Energy' , which is given the symbol (Ea).
Is turning a penny gold a chemical or physical reaction?
Anything else then dropping it in molten gold is chemical
If gold does react to water is it a chemical or physical change?
gold has no reaction in water, or acid. if there is no reaction that means no chemical reaction. the gold gets wet, or changes temperature in the water, that might be considered a physical change. gold is remarkably unreactive as far as metals go.
What respresents the chemical reaction needed to make a compound?
A variety of different ways to make new substances and they are what makes the world. Compounds Difficult to separate; a chemical reaction is needed.
What does the activation energy for a reaction represent?
Activation energy is the amount of energy needed to start a reaction.
Energy is the energy needed to start a chemical reaction?
The energy needed to statr a chemical reaction is the 'Activation Energy' , which is given the symbol (Ea).
What substance lowers the energy needed to start a chemical reaction?
A substance that lowers the energy needed to start a chemical reaction is a catalyst.
What compound is needed to start a chemical reaction?
The initial compounds in a chemical reaction are called reactants.
How can you tell fools gold from gold by using a chemical reaction?
With magnets.
Is turning a penny gold a chemical or physical reaction?
Anything else then dropping it in molten gold is chemical
What nutrient does chemical reaction take place?
Vitamin nd minerals are the nutrient needed for chemical reaction because they are needed by the body in very small amounts to allow many different types of chemical reaction to take place.These chemical reactions are needed to maintain healthy functioning of the body

What energy is needed to start a chemical reaction?
It varies with the differences in chemical reactions
What substances is needed to start a chemical reaction?
reactants is your answer
Is it true that catalysts increase the activation energy needed to start a chemical reaction?
Catalysts actually lower the activation energy needed to start a chemical reaction. This makes the reaction happen more easily.
What do chemist call the energy needed to start a reaction?
The energy needed to start a chemical reaction is called the activation energy :)
What function do catalysts perform in chemical reactions?
They speed a chemical reaction. Add: Catalysts lower the activation energy needed to start a chemical reaction.
