algebraic concepts and geometric concepts

Since it is not possible to calculate the weight of particles individually, a collection of such particles called mole is taken for all practical purposes. Avogadro discovered that under standard conditions of temperature and pressure, (1atm and 273K) a sample of gas occupies a volume of 22..

In chemistry the term mole represents a pile or mass of atoms, molecules, ions or electrons. Just as common man measures quantity in terms of kilograms or dozens, a chemical scientist deals with a 'mole' of atoms, molecules, ions or electron..

In chemistry, the term mole represents a pile or mass of atoms, molecules, ions or electrons. Just as common man measures quantity in terms of kilograms or dozens, a chemical scientist deals with a 'mole' of atoms, molecules, ions or electrons. Mole is defined as the amount of a substance, which co..

It refers to the similarly in the properties of some of the elements of 2nd period to diagonally opposite elements of 3rd period. The pair of elements showing diagonal resemblance are: LiMg, Be..Al and B.S..

Ohm's law - The potential difference across the conductor is directly proportional to the current flowing through it. Solutions obey Ohm's law like metallic conductor..

a) Open system - A system, which can exchange matter as well as energy with the surroundings is called an open system. For e.g., hot coffee in an open flask because it can gain or loose matter and energy with the surroundings. fig 4.1 - Example of open syst..

Molecular or Particle Concept of Matter - Intensive investigation by scientists over the years led to the development of a mental model known as 'dynamic particle mode..

Lewis Concept of Acids and Bases - In 1938 G.N. Lewis put forward a more generalized acid-base concept. According to this concept, an acid is a species (charged or uncharged), which can accept a pair of electrons and a base is a species (charged and uncharged), which c..
