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.
Is rusting iron a physical change in science?
no rusting iron is not a physical change it is 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.
What are examples of chemical and physical change?
melting any metal is physical. rusting iron is chemical
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.
Changes in properties of matter are called?
physical or 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.
Is shiny a chemical property of Iron?
No, shininess is a physical property of iron, not a chemical property. Chemical properties describe how a substance interacts with other substances or undergoes chemical changes, while physical properties describe observable characteristics like color, texture, and conductivity.
