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.
Explain how a catalyst aids chemical reaction to take place and identify the subsequent chemical changes in the reaction?
The role of a catalyst is to quicken the chemical reaction . On reacting, it subsequently appears as a product in the next step of the reaction.
Explain chemical changes in terms of the structure and motion of atoms and molecules?
a chemical change destroys the old atoms and molecules to make completely new ones and a completely new substance.
Are chemical changes irreversible If yes then what about the chemical reactions that are reversible Don't we say that all chemical reactions are chemical changes?
some chemical changes can be reversed but they are hard to reverse usually
Differences between physical changes and chemical changes?
Physical changes are reversible changes, such as change of state (boiling, melting etc), chemical changes are when something undergoes a reaction changing it's chemical makeup.
