What else can I help you with?
How does rust affect?
Rust is simply a product of the oxidation process. When metals are exposed to air, they break down forming a protective layer (rust)
What will happen to metals when exposed to acids?
Rust is formed in metals when it exposed to oxygen and moisture in air and in the presence of acid.
What metals dont rust?
Metals such as gold, platinum, and silver are highly resistant to rusting because they do not easily react with oxygen in the air. Stainless steel, which contains chromium, is also known for its rust-resistant properties.
What is a chemical change that happens to metals like iron?
it can rust because of the oxygen in the air
Why do metals get rusted when exposed to air for a long time?
because air has oxygen in it and rust is also known a oxidation
Name a disadvantage of ferrous metals?
They generally oxidize with exposure to the moisture in air, producing rust.
Do all metals rust?
Only metals containing iron rust. Other metals, over time, corrode.
Why do metals need to be protected against rust and tarnish?
Metals need protection against rust and tarnish because these processes can weaken the metal, leading to degradation and structural integrity issues. Rust is a form of corrosion that occurs when iron reacts with oxygen and water, while tarnish is a result of metal reacting with sulfur compounds in the air. Both can compromise the appearance and functionality of the metal.
Why do metals closer to the sea rust faster?
The sea air has moisture in it, causing the metal to corrode faster.
What gas in the air makes steel rust?
Oxygen is the only gas which rust the metals.
What metals corrode in air?
Metals such as iron, steel, and aluminum can corrode in air due to the presence of oxygen and moisture, forming rust or other types of corrosion. Other metals, like gold and platinum, are more resistant to corrosion in air due to their chemical stability.
Does all metals decompose?
No not really, metals rust. However, rust can be considered metal decomposition (kind of).
