They are all oxidation. Burning is much faster than the other two and releases large quantities of heat. Rusting and tarnishing are much slower. Tarnishing typically shows a change in color and very little in the way of physical change. Rusting slowly eats away the material as it combines with the oxygen.

Rusting is the process of iron or steel reacting with oxygen to form iron oxide (rust) on the surface. Tarnishing is the chemical reaction that occurs when certain metals, like silver or copper, react with sulfur compounds in the air to form a layer of corrosion known as tarnish. Burning is the process of a substance combining with oxygen rapidly to produce heat, light, and often flames.

What is an example of a physical change tarnishing rusting burning or melting?
Melting is an example of a physical change because it does not change the chemical composition of the substance undergoing the change. Tarnishing, rusting, and burning are examples of chemical change because they are caused by chemical reactions, which change the chemical composition of the substances undergoing the change.
What would be a physical change metal rusting silver tarnishing water boiling or paper burning?
Rusting of metal and tarnishing of silver are chemical changes because new substances are formed. Boiling water is a physical change as the water changes state from liquid to gas. Burning paper is a chemical change as the paper undergoes a combustion reaction to form new substances like ash and gases.
5 examples of chemical change?
1 Burning of paper in the air. 2 Dissolving calcium in water 3 Slaking of Lime 4 Tanishing of silver when exposed to air 5 Clotting of blood in a wound.
What is an example of a physical change burning melting rusting tarnishing?
An example of a physical change is melting ice into water. When ice melts, its physical state changes from solid to liquid without altering its chemical composition.
What type of change such as burning or rusting in which the identity of the substance changes?
a chemical change

Why are rusting and tarnishing examples of corrosion?
Rusting and tarnishing are examples of corrosion because they involve the chemical reaction of a material with its environment, leading to degradation of the material's surface. In rusting, iron reacts with oxygen in the presence of water to form iron oxide (rust), while tarnishing involves the reaction of metals with substances in the air, such as sulfur or carbon dioxide, leading to discoloration and degradation of the material's surface.

Why does a substance decompose?
A substance decomposes when the chemical bonds holding its molecules together break down. This can happen through various processes like heat, light, or exposure to other chemicals, causing the substance to break down into simpler compounds or elements.
What are chemical changes in matter?

What does corrison mean?
Corrosion is the deterioration of a material, usually a metal, due to a chemical reaction with its environment. This can lead to rusting, tarnishing, or other forms of degradation.
What is an example of a physical change burning melting rusting tarnishing?
An example of a physical change is melting ice into water. When ice melts, its physical state changes from solid to liquid without altering its chemical composition.
5 examples of chemical properties?
Flammability: the ability of a substance to burn or ignite. Reactivity: how a substance reacts with other substances to form new products. Toxicity: the harmful effects a substance can have on living organisms. Acidity/basicity: the pH level of a substance indicating its acidic or basic nature. Oxidation state: the ability of an element to gain or lose electrons in a chemical reaction.
