you have a hammer and an eraser with you can you make a chemical change using this two. explain?
Answers
Answer:
With a hammer and an eraser, the chemical change that can be made is breaking the eraser into many pieces, by repeatedly banging the eraser with the hammer.
Explanation:
This is a chemical change, because, as per the definition of a chemical change, a new substance is formed, which are the many smaller pieces of the eraser, which cannot be converted again to its previous state, because, these smaller pieces of the deranged eraser cannot be put back to its original structure.
Answer:
No we can't make a chemical change using hammer and eraser because we don't get a new substance. We can form a physical change using the hammer and eraser by breaking the eraser into pieces. We can tell that only a physical change is possible in this situation.
Explanation:
we can't make a chemical change because if we break the eraser into pieces, no new substace will be formed. And physical changes are not neccesary to be reversible. If we break the eraser we will get the eraser only in small pieces. So, we didn't get any new substace.
