ON TIPS
NOTES
Note making is a skill that we use in many walks of life : at school, university and in the world
of work. However, accurate note making requires a thorough understanding of concepts. We, at
Oswaal, have tried to encapsulate all the chapters from the given syllabus into the following ON
TIPS NOTES. These notes will not only facilitate better understanding of concepts, but will also
ensure that each and every concept is taken up and every chapter is covered in totality. So go ahead
and use these to your advantage... go get the OSWAAL ADVANTAGE!!
CHAPTER 1 : Atoms and Molecules
Ø Laws of chemical combination : There are two laws as mentioned below :
(i) Law of conservation of mass : Mass can neither be created nor destroyed in a chemical
reaction.
(ii) Law of constant proportions or Law of definite proportions : In a chemical substance, the
elements are always present in definite proportions by mass.
