An inequation is a mathematical statement that states that one quantity is not equal to the other. On transferring a positive term (the term in addition) from one side of an inequation to the other side, the sign of the term becomes negative. On transferring a negative term from one side of an inequation to […]

Nitrogen: dilutes the effect of oxygen and controls the rate of combustion. Needed for proteins and important compounds like fertilizers, ammonia, and nitric acid. Used to keep food fresh because it does not allow the growth of oxygen by preventing oxidation. Oxygen: needed to sustain life, and for combustion Carbon dioxide: needed for photosynthesis, retains
Atoms are the smallest unit of matter. Elements are made of the same type of atoms. They are represented by a symbol. Compounds have different kinds of atoms combined in fixed ratios. They are represented by a formula. Molecules are the smallest unit of elements or compounds which can exist independently. The number of atoms
Naturally occurring substances of metals present in the earth’s crust are called minerals. The method used in the extraction of minerals from their ores profitably is called metallurgy. Minerals that can be used to obtain the metal profitably are called ores. Metals and Non-metals PDF Download PDF
Allotropy is the phenomenon where an element exists in two or more forms with identical chemical properties but different physical properties…… Carbon and Its Compounds PDF Download PDF
Boiling point: the temperature at which liquid changes to a vapor state under normal atmospheric pressure. Melting point: the temperature at which solid changes into liquid at normal atmospheric pressure. Impurities cause an increase in boiling point and a decrease in melting point.
