Photoelectric Effect

Image
Photoelectric effect:         Photon:                  in 1905 Einstein suggest that light(electromagnetic radiations) is made up of tiny particles known as photon . photons are the packets of energy . Einstein suggested that energy is not emitted continuously but is emitted as individual amount of energy known as Quantum energy. Energy of Photon: The energy of photon is given by Einstein                                      E=hv where,                E= energy of photon                h=plank's constant                v=frequency Properties of Photon: Photon have no mass. Photon posses no charge and are not deflected by electric or magnetic field. The values of all quantum number...

Definitions of solute Solvent and Solution

Image
Definitions of solute  Solvent and Solution, Solute: solute may be a substance that may be dissolved by a solvent to form a solution. A solute may be available in several forms. It can be gas, liquid, or solid. The solvent is a substance that dissolves the solute and  breaks the the solute apart and distributes solute molecules equally. This makes a homogeneous mixture (solution) that's same throughout. Example : An example of a solute is sugar dissolving in water. Solvent: solvent is that the element of a solution which is present in the largest quantity. it's the substance in which the solute molecule are dissolved. Example: • The solvent for sugar is water. • Nitrogen is solvent for air. Solution: The homogeneous mixture of two or more  substances is called solution. A solution can be present in any  state. It consists of a solute and a solvent. The solute is that the substance that's dissolved within the solvent. the number of solute mole...

Isomerism

Image
Isomerism The phenomena in which compounds have same molecular formula but different structural formula is called isomerism. e.g propadiene propyne Structural Isomers  having different structural formulas because their atoms are joined together in different number of ways. It is formed: arrangement of Carbon skeleton e.g. The formula of C4H10 gives two possible structure, butane and methylpropane: butane methyl propane   Position isomerism e.g. propan-1-ol and propan-2-ol  Functional Isomerism e.g. the molecular formula C2H60 represents both ethanol and methoxymethane.  Ring chain isomerism Cyclic alkanes are isomeric with alkenes, e.g. cyclopropane and propene
