Allotropy & Allotropes Of The Oxygen

Allotropy & Allotropes Of The Oxygen
Allotropy & Allotropes Of The Oxygen

Allotropy & Allotropes Of The Oxygen

The word Allotropy has been derived from two words Allos means other and Tropes means form. Thus it is defined as The existences of more than one forms of an element in same physical state having same chemical properties but different physical properties are called allotropes or allotropic forms and this phenomenon or process is called allotropy”.

Example: Diamond and graphite are the allotropic form of carbon.

Oxygen (O2) is color less.

  •  O2 is for life. Plants and animals cannot live without it.
  • The most energetic ultra violet (UV) radiations, which are harmful for both plants and animals, are absorbed by oxygen in atmosphere.
  • Rockets carry liquid O2 as a fuel in space.
  • Oxygen cylinders are used to aid patients of pneumonia and gas poisoning.
  • Oxygen cylinders are used for breathing, while climbing on mountain, flying at high altitudes and in submarines.

Ozone (O3): is blue.

  • The less energetic ultra violet (UV) radiations, which are very harmful for both plants and animals, are absorbed by ozone.
  • Ozone is poisonous, therefore can be used for disinfecting water.
  • Ozone is used to sterilize air in crowded areas such as underground railway stations and slaughter houses.

Calculation Of Weight & Mole % Of Sulphur In 50g Of Sulphuric Acid

Calculation Of Weight & Mole % Of  Sulphur In 50g Of Sulphuric Acid
Calculation Of Weight & Mole % Of  Sulphur In 50g Of Sulphuric Acid


Calculation Of Weight & Mole % Of  Sulphur In 50g Of Sulphuric Acid

Data Given:               
       Mass or amount or quantity of H2SO4      =         50g
Requirement:       
      Percentage of Mass or weight of sulphur in 50g H2SO4    =  ?
      Percentage of Moles of sulphur in 50g H2SO4                   = ?
       Solution For Calculation:    
      
     As we know that
     
 Number of Moles of H2SO4        =               Mass / Molar Or Molecular Mass 
    
 Relative molecular mass (Mr) of H2SO4    =     H2            +            S              +         O4   

 Relative molecular mass (Mr) of H2SO4   =   (2×1)        +         (1 × 32)           +     (4×16)
 Relative molecular mass (Mr) of H2SO4    =      2              +             32                    +        64
 Relative molecular mass (Mr) of H2SO4    =     98a.m.u


Now Putting the values in above equation 

Number of Moles of H2SO4            =    50 / 98        
Number of Moles of H2SO4            =    0.51      Answer.

Number Moles of S in 50 g H2SO4

H2SO4             :                   S
1                        :                      1
0.51: 1               ::                    1 : x
0.51x                 =                   1 × 1
X                       =                      
X                       =                      1.96

Moles of sulphur is 1.96 moles in 50g of sulphuric acid (H2SO4).
Number Moles of S    in 50 g H2SO4   =   (1.96 / 0.51) × 100

 Number Moles of S    in 50 g H2SO  =       3.843 × 100

  Number Moles of S    in 50 g H2SO4  =      384.313%

Percentage of Mass or weight of sulphur in 50g H2SO4   =  (32 / 50) × 100   
Percentage of Mass or weight of sulphur in 50g H2SO4    =  0.64    10    
Percentage of Mass or weight of sulphur in 50g H2SO4    =  64%

Electronegativity Importance & Uses For Chemists

Electro-negativity is important for chemists because it has following usages:
  • Electro-negativity is used to predict the reactivity and bond type. The elements having highest value of electro-negativity are more reactive. Such as Fluorine (F) with highest electro-negativity value of 4.0 is the most reactive element of the periodic table.
  • Electro-negativity is used to calculate the bond type as follows
  • If electro-negativity difference is 1.7 then the bond is 50% covalent and 50% ionic.
  • If the electro-negativity difference is greater than 1.7 then the bond is ionic.
  • If the electro-negativity difference is less than 1.7 then the bond is covalent.
  • If the electro-negativity difference is less than 0.5 then the bond in an atom is non-polar.
  • If the electro-negativity difference is greater than 0.5 but less than 1.7 then the bond is polar covalent one.

The Inertness of Nobel gases.

The Elements form bonds to complete their outermost shell. Nobel gases have complete outermost shells therefore they don’t make bonds with other elements, because they don’t need to complete their outermost shells.

]]]]]]]]]]]]]]]

 Why it is necessary to classify the Elements? Explain with reasoning.

 Ans: Up till now approximately 118 elements have been discovered. Thus it is difficult to study each and every element separately. Therefore it is necessary to classify these elements, in order to study their physical and chemical properties.

]]]]]]]]]]]]]]]

Discuss the importance of groups and periods in the modern periodic table?

Groups show the number of electrons in the last shell of an element, while periods show the total number of shells present in one atom of a element. These both: shells and electrons are extremely important in studying the properties an element.

The Evolution Of Periodic Table

The Evolution Of Periodic Table
The Evolution Of Periodic Table

The Evolution Of Periodic Table

Various attempts were made by scientists to give more précised periodic table: E. g:
  • Dobereiner proposed triads in 1820,
  • Newlands proposed Octaves in 1860
  • Mendeleev for the first time classified elements on the basis of their atomic masses in 1865.

All these attempts mentioned above had draw backs. After the discovery of proton, proton number built up. On the basis of which in 1913 Moseley presented an accurate periodic table of elements. He arranged elements according to their atomic number. As result similar elements were placed in same group and different elements were placed in different groups. Now it is easy to understand and determine both chemical and physical properties of elements.

The Modern periodic law? Explain with examples.
Ans. This law states that the physical and chemical properties of an element are the periodic functions of their atomic number”. E. g:
  • The physical and chemical properties of Alkali metals repeat after an interval. As result the Alkali metals having similar properties are placed in the same group. 
  • The physical and chemical properties of halogens also repeat after an interval. As result all the halogens (salt formers) are placed in the same group. And so on.
