acid+metal-->salt plus hydrogen
chemical
it changes to green
it would be a chemical property because is changes
Yes, metal rusting is a chemical change in matter. It involves the metal reacting with oxygen in the presence of moisture to form a new compound (rust), which changes the chemical composition of the metal.
The process called when metal is destroyed by a chemical reaction is called Corrosion. Electrochemical of oxidation of metals reacts with oxygen thus corrosion will occur on metals.
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.
Physical Changes in metal are: melting bending and rusting
No, the release of energy when sodium metal reacts with chlorine gas is a chemical property, not a physical property. Chemical properties involve changes in the chemical composition of a substance, while physical properties are characteristics that can be observed without changing the substance's composition.
The metal reacts with oxygen, causing a chemical reaction which makes it turn brittle and orange
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.
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.
Magnesium is the metal which reacts with oxygen to form magnesium oxide.
