What is happening when metal is corroding?
The metal is getting rusty!
How does painting a metal surface stop it from corroding?
Usually you have to stop it corroding FIRST, then paint it to protect it.
Is corroding metal a chemical change?
Yes, corroding metal is a chemical change because it involves a chemical reaction between the metal and substances in its environment, such as oxygen or water. This reaction causes a change in the composition and properties of the metal.
How is metal corroding a chemical change?
When a metal corrodes, it reacts with a chemical in the environment to produce a new substance. Often the metal reacts with oxygen to form a metal oxide. A well-known example is iron reacting with oxygen to form iron oxide, known as rust.
Is metal corroding a physical change or chemical change?

How does rust affect the durability of metal objects?
Rust weakens metal objects by corroding them, making them more prone to breaking or deteriorating over time.
Which of the following is an example of when corrosion of metals can actually be beneficial A. Pure aluminum and pure titanium corroding in air B. Pure zinc corroding in weak hydrochloric acid C.?
THERMITE
Is gold a very reactive metal?
No. Gold is very nonreactive, which is one of the reasons it is considered a precious metal: it can last for thousands of years without corroding or tarnishing.
What is corroding?
Corroding is erosion by chemical action, to keep it simple.
What happen to a metal exposed to an acidic mixtures?
When a metal is exposed to an acidic mixture, a chemical reaction occurs that can result in the metal corroding. The acid reacts with the metal to form metal ions and hydrogen gas. This process is known as corrosion and can weaken the metal over time.
Is metal corroding chemical change?
Yes. When metal rusts the iron is changed into iron oxide. This type of change is called a redox reaction. The iron is oxidized, meaning is has lost electrons.
