If copper metal rusts would it be a physical change?
If you use a abrasive to scrape the rust off, then it is a physical change. If you utilize a chemical that combines with the rust leaving the unoxidized penny behind, then it is a chemical change.
What is the chemical reaction in cleaning a penny?
A copper penny builds up a layer of corrosion on its outsides. Probably copper oxide. The cleaning just dissolves the outer corrosion and leaves a new outer layer of copper. CuO + HNO3 --> Cu(NO3)2 + H2O ... the copper nitrate is dissolved in the acid solution and leaves 'clean' copper behind.

What remains when water is evaporated after a neutralization reaction?
After water is evaporated from a neutralization reaction, any remaining substances would be the salt that was formed as a result of the reaction between an acid and a base. Salt is the compound left behind after the water has been removed.
Describe the corrosion casting process used to prepare these specific specimens?
Corrosion casting involves injecting a liquid polymer into blood vessels. After the polymer cures, the surrounding tissue is chemically removed, leaving behind a detailed cast of the vasculature. This process helps visualize the intricate structure of blood vessels for research or educational purposes.

Why is corrosion considered oxidation?
because when corrosion occours on a metal the chemical reaction is an oxidation. This means that the metal will loose electrons and became a positive ion. Fe ------> Fe 2+ + 2 e- The iron is oxydised from metal to metal ion.

Why does paint protect iron from rusting?
Painting of iron prevent it from rusting because it prevent the iron articles coming in Contact with oxygen, or water vapours present in the air.
What is the science behind hydrogen fuel cells?
Hydrogen fuel cells produce electricity by combining hydrogen and oxygen in an electrochemical process. When hydrogen is fed into the anode and oxygen into the cathode, a chemical reaction occurs, producing electricity, water, and heat as byproducts. This clean and efficient process makes hydrogen fuel cells a promising technology for powering vehicles and other applications.
What is the reason behind ozone hole?
The main reason behind ozone hole is the reaction of the chlorine molecules from CFC's. These molecules initiate a chain reaction which then destroy the ozone molecules to form the ozone hole.
Where is the fusible link on 95 Chevy G20?
my 1990 the fusible link is in behind the battery on the drivers side. nice place for corrosion
How does a lemon battery work and what is the science behind its ability to generate electricity?
A lemon battery works by using the acid in the lemon as an electrolyte to create a chemical reaction that generates electricity. The citric acid in the lemon reacts with the metal electrodes (usually zinc and copper) to create a flow of electrons, which produces a small amount of electrical energy. This process is known as an electrochemical reaction, where the transfer of electrons between the electrodes creates a voltage difference that can be used to power a small device.

A lemon battery works by using the acid in the lemon as an electrolyte to create a chemical reaction that generates electricity. The citric acid in the lemon reacts with the metal electrodes (usually zinc and copper) to create a flow of electrons, which can be harnessed as electrical energy. This process is known as an electrochemical reaction, where the transfer of electrons between the electrodes creates a voltage difference that can power a small device like a light bulb or a clock.
