Avogadro's number

 Hello readers! I hope you all will be fine and enjoying my blogs. Today we discuss about Avogadro's number. 

Avogadro's Number is a collection of 6.02×10²³ particles.It is represented by symbol 'NA'. Hence, the 6.02×10²³ number of atoms, molecules or formula units is called Avogadro's number that is equivalent to one 'mole' of respective substance. In simple words, 6.02×10²³ particles are equal to one mole as twelve eggs are equal to one dozen.

To understand the relationship between the Avogadro's number and the mole of a substance let us consider a few examples.

i.6.02×10²³ atoms of carbon are equivalent to one mole of carbon.

ii. 6.02×10²³ molecules of H2O are equivalent to one mole of water.

iii. 6.02×10²³ formula units of NaCl are equivalent to one mole of sodium chloride.

 Thus, 6.02×10²³ atoms of elements or 6.02×10²³ molecules of molecular substance or 6.02×10²³ formula units of ionic compounds are equivalent to 1 mole.

Carbon Cycle

CARBON CYCLE: Carbon circulates through the carbon cycle. It shows that carbon may be pres- ent as gaseous atmospheric CO2 constituting a relatively small but highly significant portion of global carbon. Some of the carbon is dissolved in surface water and groundwater as HCO-3 or molecular CO2 (aq). A very large amount of carbon is present in minerals, particularly magnesium and calcium carbonates such as CaCO3. Photosynthesis fixes inorganic C as biological carbon. represented as (CH2O), which is a constituent of all life molecules. Another fraction of carbon is fixed as petroleum and natural gas, with a much larger amount as hydrocarbonaceous kerogen (the organic matter in oil shale), coal, and lignite. Manufacturing processes are used to convert hydro- carbons to xenobiotic compounds with functional groups containing halogens, oxygen, nitrogen, phosphorus, or sulfur. Although a very small amount of total environmental carbon, these com- pounds are particularly significant because of...

Structure of Atom(Part 5)

 Rutherford's Atomic Model: Rutherford performed 'Gold Foil' experiment to understand how negative and positive charges could coexist in an atom. He bombarded alpha particles on a 0.00004  cm thick gold foil. Alpha particles are emitted by radioactive elements like radium and polonium. These are actually helium nuclei (He2+). They can penetrate through matter to some extent. He observed the effects of α-particles on a photographic plate or a screen coated with zinc sulphide. He proved that the 'plum-pudding' model of the atom was not correct.  Observations made by Rutherford were as follows: i.Almost all the particles passed through the foil un-deflected. ii.Out of 20000 particles, only a few were deflected at fairly large angles and very few bounced back on hitting the gold foil. Results of the experiment: Keeping in view the experiment, Rutherford proposed planetary model for an atom and concluded following results: i.Since most of the particles passed through th...

Chemical species

  Hello! Welcome to my blog. Today we will discuss about chemical species. lets start. If one  molecule  is identical to another, we can say they are the same chemical species. Ion: It is an atom or group of atoms having a charge on it. The charge may be positive or negative.  There are two types of ions:       Cations: An atom or group of atoms having positive charge on it is called cation. They are formed when atoms lose electron from their valance shells. Examples:   Ca 2+   Ag +    Al 3+     H 3 O +     NH 4 +     Hg 2 +2      Fe +2     Fe  +3        Anions: An atom or group of atoms having negative charge on it is called anion. They are formed by gain or addition of electron to an atom. Examples: Cl –    OH –      I –     Cr 2 O 7 -2     O -2      SO ...
