Is turning a penny gold a chemical or physical reaction?
Turning a penny gold is a physical reaction rather than a chemical reaction. This process involves coating the penny with a layer of gold, which changes its appearance but does not alter the chemical composition of the penny itself.
Is gold plating chemical reaction or physical reaction?
Gold plating on non-metals is a physical change. There is no chemical change when a wood, glass, ceramic, marble or plastic is being plated . However, Electroplating is a chemical change because when a metal is being plated with another metal, there is a chemical reaction.
Why is it not possible to turn lead into gold by chemical reaction?
Lead and gold are elements, made up of completely lead and gold atoms, respectively. Elemental atoms cannot be created or changed. They can only combine to form molecules. An element can never become another element.
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.
Why is no chemical reaction needed to get gold?
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.

How can you tell fools gold from gold by using a chemical reaction?
With magnets.

What do you call substances that are made by a chemical reaction?
The results of a chemical reaction are called the products, and the reactants are what goes into the reaction
If new products are made in a chemical reaction what does that suggest about the reaction?
No new products can be made in a chemical reaction. Only the reactants exchange or react with another element.

Are bubbles made by a chemical reaction?
yes
What is the name for a chemical made in a reaction?
A chemical produced from a reaction is usually referred to as the product of the reaction. While the initial chemicals are known as reactants.
