    Chemical change is any change that results in the formation of new chemical substances. At the molecular level, chemical change involves making or breaking of bonds between atoms. A quantity is a measure of something. For example volume, weight or distance.

    This measure is given as a number.

    A unit is a specified measure of a quantity against which the magnitude of other quantities of the same kind can be measured. For example: 1 liter of milk is the same quantity as 1 liter of water. A conversion factor is a ratio written in fraction form that can express the same value or quantity in two different units.

    A derived unit is like radians. Actual units like degrees or cm, or inches have been devided out so there are no actual dimensions to the number and are called derived units and given their own names.

    Its observable. Homogeneous mixture and Heterogeneous mixture are the two types of mixtures. Homogeneous mixture — mixtures that have definite, consistent properties all throughout the process.

    Heterogeneous mixture — mixtures with inconsistent, non-uniform composition. The parts of a heterogeneous composition can be mechanically separated from each other. Examples include salad, trail mix and granite. Natural foods are made of chemicals as well.

    The first chapter is all about the basic of Chemistry from the definition of Chemistry to its main branches, from empirical formula to formula mass, from Chemical species to Avogadro's number. The basic concepts of all these topics are extremely important. Make use of Youtube to learn the topics if you don't understand.

    This chapter is dedicated to Atom. Important questions are taken from cathode rays and its characteristics.

    And how Proton and Neutron were discovered with the help of discharge tube. Rutherford's experiment is also important and its defects for a short question. Try to clear your concepts about isotopes about hydrogen and carbon with diagrams. This chapter is truly focused on Periodic Table, and its basic understanding.

    The concepts explained in this chapter are extremely important for exam prospective and when you will enter F. Sc level. Ionization energy, shielding effect and electron affinity are critical and easy to understand. It's a game played between the electron and the neutron. The closer the electron is with neutron, the stronger its attraction is, lesser in size, but has a high value of ionization energy and electron affinity.

    This chapter is one of the most important chapters for your exams. This chapter is about how an atom mingles with each other in order to be a part of a bond either it is ionic bond or covalent bond. The most interesting question is why an atom forms a chemical bond?

    Because it wants to be more stable as you study to be a doctor or an engineer or a biologist. Ever person wants to be rich, the same goes for atom too. Physical States of matter are discussed, and its laws. This chapter is all about solution.

    Not that solution to your common problems that you face in your life :. Rather it is about water solution. Saturated and super saturated solutions are the most important questions. Then the concentration units are important for MCQs, and short questions.
