What else can I help you with?
Chemical changes can be reserved by physical change?
No, chemical changes cannot be reversed by physical changes. Chemical changes involve the formation of new substances with different properties, while physical changes only affect the state or appearance of a substance without changing its chemical composition. Once a chemical change occurs, it cannot be undone by a physical change.
Can chemical changes reverse by physical means?
No, physical
What changes can't be reveresed by physical means?
Chemical changes.
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 changes can't be reversed by physical means?
Changes that involve irreversible chemical reactions, such as burning wood to ashes or baking a cake, cannot be reversed by physical means. Once the chemical bonds are broken or rearranged, it is not possible to return the substances to their original state through physical processes alone.
Is a flammable a chemical or a physical?
Flammable is a chemical property. Flammable means that the substance will burn. Burning or combustion involves chemical changes as the substance is oxidised.
What can be seprated by chemical means but not by physical means?
The elements of a chemical compound can be separated only by chemical means, but not by physical means.
Physical and chemical propertires?
Physical means the color, density, state of matter, its structure etc etc. But chemical means how it reacts with water, acid, base and how it changes when it is heated with some other chemicals etc.
How do you separate mixtures and compounds?
You can break down a mixture by physical means
What name do you give to temporary changes into materials?
Temporary changes in materials are often referred to as physical changes. These changes do not alter the chemical composition of the material and can usually be reversed by physical means. Examples include changes in state (e.g. melting, freezing) or changes in shape.
What other than physical means can matter be separated?
Only physical means; chemical means alters the chemical composition.
Is flammable a chemical properties or physical property?
Flammability is a chemical property because when you burn something there is a chemical reaction, therefore a chemical change will occur.
