Is boiling water a chemical or physical process?
Water boiling is a physical change and not a chemical reaction. In a physical reaction there is no new substance formed as is the case with chemical reactions. In boiling water there is no new substance produced.
What is a ''non'' reversible reaction?
A reaction which cannot be reversed is called an Irreversible reaction.
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.
Explain what a chemical change is?
a chemical change is a change which brings about a change in the chemical properties of a substance which cannot be reversed through physical means like heating or cooling.

the redox reaction is reserved
Is the boiling of alcohol physical or chemical reaction?

Can antacid reaction be reversed?
no. it is a chemical reaction. and so it cannot be reversed.
Can a neutralisation reaction be reversed?
Yes it can
What are example of a physical change that can be reversed and an example of a physical change that cannot be reversed?
an example of a physical change that can be reversed is like freezing water and letting melt back into water again
Is milk rotting a physical or chemical reaction?
Physical changes are like water turning into ice, they can be reversed. Chemical changes form a new substance. Soured milk can not be reversed, so it is chemical.
Is making salt by mixing sodium and chlorine together a physical or chemical change?
It is a physical change because the reaction can easily be reversed and no heat is involved.
What is a ''non'' reversible reaction?
A reaction which cannot be reversed is called an Irreversible reaction.
Is TNT explosion a chemical property?
A chemical reaction occurs but this is a physical change since it can't be reversed.
