"A voltaic cell is the device in which the transfer of electrons takes place through an external pathway. The flow of electrons in a voltaic cell enable energy in form of electricity to be produced in ...
"Vapor pressure lowering is a colligative property of solutions. The vapor pressure of a pure solvent is greater than the vapor pressure of a solution containing a non volatile liquid. This lowered va ...
"The law of definite proportions, also known law of definite composition, states that regardless of the amount, a pure compound always contains the same elements in the same proportions by mass. Law o ...

"Vapor pressure is the pressure caused by the evaporation of liquids. Three common factors that influence vapor press are surface area, intermolecular forces and temperature. The vapor pressure of a m ...

"Valence electrons are the outer electrons that are involved in bonding. Only electrons in the s and p orbitals are valance electrons, so a given atom can have between 0 and 7 valance electrons. Atoms ...
"The law of conservation of mass states that mass is neither created nor destroyed. In a closed system, mass of reactants is equal to mass of products. The law of conservation of mass is related to th ...
"Kinetic and potential energy of atoms result from the motion of electrons. When electrons are excited they move to a higher energy orbital farther away from the atom. The further the orbital is from ...

"Isomers are compounds of the same molecular formula but different molecular structures. There are four important types of isomers. Structural isomers’ atoms are bound in different orders while stere ...

"Ionization energy is the minimum energy required to remove an electron from the ground state of an atom. Ionization energy is a periodic trend which increases going from top to bottom and left to rig ...
