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.
How is sour milk a chemical change?
When milk turns sour, it is a chemical change because the bacteria in the milk ferment the lactose sugar into lactic acid, which changes the composition of the milk. This process cannot be easily reversed, making it a chemical change rather than a physical one.
What is the difference between a chamical and physical change?
A chemical change results in the formation of new substances with different chemical properties, while a physical change involves a change in appearance, state, or form of a substance without altering its chemical composition. Chemical changes are usually irreversible, while physical changes can often be reversed.
What are the differences between the physical and chemical?
in changes. Physical changes can be reversed. E.g. if you were to melt a block of ice, and then freeze it again, it would to some degree be reversed. This is a physical change. However, if you were to burn a peace of toast, the change would be chemical. Once the toast is burnt you cant get it back.
Is melting a physical or chemical property of sulfur?
Physical - because melting isn't a change in it's chemical structure, it has just changed its physical state of matter. Generally (but not always) physical changes are reversible (can be taken back) but chemical ones cannot be reversed easily.
Is melting ice a chemical or physical change explain?
It is a physical change because when you have a chemical change it changes the properties and makes it into a new thing, and it can't be reversed. Physical changes are usually just changes of states (solid, liquid, gas) and a physical change can be reversed.
Chemical changes can be reserved by physical change?

Explain Why physical changes can be reversed but chemical changes cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
What are three differences between physical and chemical changes?
(i) Physical change does not result in formation of new substances Chemical change result in formation of new substances (ii) Physical change is a temporary change Chemical change is a permanent change (iii) Physical change is reversible Chemical change cannot be reversed back (iv) e.g of Physical change-Dissolving of sugar in water to obtain a sugar solution e.g of Chemical change-Burning of sodium in chloride
How is sour milk a chemical change?

Why physical change can easily be reversed but chemical change cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
Why physical changes can easily be reversed but why chemical cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
What is the difference between physically and chemical changes?
A chemical change is when something cannot be reversed and often a precipitate (solid) is formed. While a physical change can be reversed e.g bending a piece of wire.
What is the difference between chemical and physical changes?
Chemical changes involve the rearrangement of atoms to form new substances with different chemical properties. Physical changes, on the other hand, only affect the physical state of a substance (such as its shape, size, or phase) without changing its chemical composition.
Why rotting wood is a chemical change?
Rotting wood is a chemical change because the decomposed wood has different properties that cannot be reversed. Chemical changes alter the identity of a substance, whereas physical changes do not.
What is the difference between a chamical and physical change?
A chemical change results in the formation of new substances with different chemical properties, while a physical change involves a change in appearance, state, or form of a substance without altering its chemical composition. Chemical changes are usually irreversible, while physical changes can often be reversed.
Can a chemical changes be reversed by physical changes?
Technically no..... however; the application of "extreme" physical forces can cause chemical change such as applying exiremely high pressure to coal to cause the formation of diamond.
