Is making iron from iron ore a chemical or physical change?
Preparation of pure iron from iron ores involve physical changes but also chemical changes.
Which of the following processes involves both physical and chemical changes?
Rusting of iron involves both physical and chemical changes. The physical change involves the formation of iron oxide on the surface of iron, while the chemical change involves the reaction of iron with oxygen in the presence of water to form iron oxide.
Is rusting of an iron fence physical change?
yes. rust is a chemical change that occurs when you mix iron, air, and water. it reacts with the iron and actually erodes it. a n example of a physical change would be the bending or cutting of iron.
When an iron ball rusts is it a physical change or chemical reaction?
When an iron ball rusts, it undergoes a chemical reaction. This process involves the iron reacting with oxygen and moisture in the environment to form iron oxide, commonly known as rust. Unlike physical changes, which only alter the form of a substance without changing its chemical composition, rusting changes the iron's chemical structure. Thus, rusting is classified as a chemical change.
Is iron rusting a chemical or physical change?
Iron rusting is a chemical change: oxidation of the metal by oxygen in the air or water. When iron 'rusts' it oxidises. This is a chemical change, a physical change is when a molecule changes state, for example iron melting and going from a solid to a liquid.
Is rusting iron a physical change in science?
no rusting iron is not a physical change it is a chemical change
What are examples of chemical and physical change?
melting any metal is physical. rusting iron is chemical
Is the magnetism of a strip of iron chemical or physical change?
The magnetism of a strip of iron is primarily a physical change. When iron is magnetized, the alignment of its internal magnetic domains changes, allowing it to exhibit magnetic properties. This process does not alter the chemical composition of the iron; thus, it remains a physical transformation rather than a chemical one.
Is a tin can rusts a physical or chemical change?
Yes, it is, because the chemical composition of the outside changes due to oxydation.
What is a physical change Milk becomes sour an iron nail rusts?
A physical change refers to a change in appearance or state that does not alter the chemical composition of the substance. When milk sours, it undergoes a physical change because its appearance and taste change, but the molecules remain the same. Similarly, when an iron nail rusts, it is a physical change because the iron's appearance changes as it forms rust, but the chemical composition of the iron is not altered.
What are the chemical and physical changes of photosynthesis?
There are no physical changes. there are only chemical changes.
What is the differnce between physical and chemical change?
Physical changes are changes in appearance, state, or form of matter without altering its chemical composition. Chemical changes involve the formation of new substances with different chemical properties. Examples of physical changes include melting ice or tearing paper, while examples of chemical changes include rusting of iron or burning wood.
