Are all physical changes are reversible changes?
yes , all the physical changes are reversible changes.
All the activities to show that physical changes are usually reversible?
physical changes are sometimes reversible
Are all physical changes reversible with examples?
Not all physical changes are reversible because most times when such changes occur parts of the substance is lost to the environment.
Which are more in nature reversible or irreversible chemical reactions?
irreversible
Is cornflour and water reversible?
Yes it is. This is a physical reaction (this means no new substance has been formed), most physical reactions are easily reversed. A glass sinter filter would be able to separate out the cornflour from the water.
What chemical reactions are reversible?
All physical changes are reversible.
Is the reaction reversible?
chemical reactions are irreversible but physical changes are reversible
What are reversibile reactions?
Reversible reactions usually involve a reaction that changes the physical state of the substance, not the chemical properties
Are all physical changes are reversible changes?
yes , all the physical changes are reversible changes.
When elements form compounds can the elements not be recovered?
some but not all......many reactions are reversible and many r irreversible....depends on chemistry of reactions, physical change or chemical change...
All the activities to show that physical changes are usually reversible?
physical changes are sometimes reversible
Are all physical change reversible?
No,they are not.
Why concept of limiting reactant is not applied to reversible reaction?
Concept of limiting reactant is not applicable to the reversible reactions because in these reactions all the reactants are converted into products and no reactants remain at the end of the reaction.
How are chemical reactions different to reversable changes?
physical change is reversible because you can undo it for example: if you fold a paper you unfold the paper. chemical chang is irreversible because if you make somthing together you could not seperate them.
Is making crisps from cooking oil and potatoes a reversible change or chemical reaction?
Most cooking processes are chemical reactions. Generally, the reactions are non reversible and once cooked, food cannot be returned to an uncooked state. So, frying potatoes causes a non reversible chemical reaction. The question is not as precise as it might be. Changes can be physical or chemical. They can also be reversible or non reversible but it is important to note that many chemical changes are reversible just as many physical changes are reversible.
Why reversible reactions never complete?
Because reversible reactions are continuting process as well two way process.reactant n product convert into one another and in this way reaction will continue.
Why can a chemical physical change not be reversed?
1. The chemical nature of the chemicals was modified; but reversible chemical reactions exist.2 . During a physical change the molecular structure of chemicals is not changed.
