Oxides As a Binary Compound

Oxides As a Binary Compound

Hi viewers: Today we will discuss about the Oxides As a Binary Compound, which are present in the nature. OXIDE Oxide: Oxide is a binary compound in which one of the elements is oxygen. E.g. Na2 O , C O2 Mainly there are two types of oxide : i) ACIDIC OXIDE ii) BASIC OXIDE iii)  NEUTRAL OXIDE iv) AMPHOTERIC OXIDE v) PER OXIDE vi) MIXED OXIDE   ACIDIC OXIDE:  Oxide of Non- metals are acidic oxide. E.g.  C O2 ,  NO2  ,  SO2 ,  SO3 ,  P2O5   Acid is formed mainly by adding water with Acidic oxide E.g. C O2 + H2 O = H2 CO3 [ carbonic acid] S O2 + H2 O = H2 SO4 [ sulpharous acid] S O3 + H2 O = H2 SO4  [ sulphuric acid ] N O2 + H2 O = H NO3 [ nitric acid ] P2 O5 + H2 O = H3 PO4 [ phosphoric acid]     BASIC OXIDE:   Oxide of metals are basic oxide. E.g.  Na2O ,  K2 O , Ca O , Mg O , Zn O , Al2 O3   Base is formed...

How to know the different types of Chemical Reaction

How to know the different types of Chemical Reaction

Hi viewers: In this blog we will discuss, How to know the different types of Chemical Reaction.  If  you just have a quick browse over this article then you will have an idea about the different types of chemical reactions that occur in the natuer.   How to know the different types of Chemical Reaction Types of Chemical Reactions   Simple Contact:   When Iodine comes in contact with white phosphorus it catches fire. 3I2  +  2P   =   2PI3   Sodium combines with cold water vigorously with a hissing sound to produce sodium hydroxide and hydrogen Na  +  H2O  =  NaOH  +   H2   Sodium combines with fluorine with violently to produce sodium fluoride Na  +  F  =  NaF  (even in dark)   Hydrogen combines with fluorine with an explosion to produce hydrogen fluoride H  +  F  +  HF   Decomposition or Pyrolyis:   Mercuric oxide decomposes into mercury and oxygen when heat is applied on it 2HgO  =  2Hg  +   O2   Potassium Chlorate decomposes into potassium chloride and oxygen when heat is applied on it 2KCLO3 =  2KCl  +  3O2       Light:  Some...

How to figure out Oxidation and Reduction Reactions

How to figure out Oxidation and Reduction Reactions

How to figure out Oxidation and Reduction Reactions Hi viewers: Today we will discuss How to figure out Oxidation and Reduction Reactions.  In chemistry there are many reactions which are oxidation reactions and many reactions are reduction reactions and even both oxidation and reduction reaction.  Students often get confused in figuring out the oxidation reaction and reduction reactions. Now let us check out : OXIDATION REACTION Oxygen or electronegative element or radical gets added to a substance C    +    O2    =    CO2 Fe   +    Cl2   =    Fe Cl2   Removal of hydrogen MnO2    +    4HCl    =    MnCl2     +    Cl2    +    2H2O   Increase in positive valency +2                                  +3 2FeCl2    +    Cl2    =    2FeCl3     Reduction reaction   Hydrogen or electropositive elements or radicals gets added to a substance H2    +    Cl2    =    2HCl   Addition of hydrogen Hg2    +    Cl2    =    Hg2Cl2   Decrease in positive valency +2                              0 CuO    +    H2    =    Cu    +    H2O  OXIDATION AND REDUCTION REACTION 6CO2 +  12H2O  =  C6H12O6  +  6H2O  + 6O2 The above reaction is Photosynthesis reaction, which...

How to distinguish between Metals and Non-Metals

How to distinguish between Metals and Non-Metals

Hi viewers: Today in this blog we will discuss firstly the properties of metals and non-metals, then we will discuss How to distinguish between metals and Non-Metals.   How to distinguish between Metals and Non-Metals Actually there is a very short cut way to figure out which one is metal.  It is because the metal will take the suffix - '"um"" like Sodium and Potassium.  Exception is Helium.  It is a gas.  But Iron do not have suffix '"um"" and it is still recognized as a metal because its Latin name has got -um suffix like Ferrum. Elements are grouped into two classes metal and non-metal Metals and non-metals are classified under some physical and chemical properties Properties of Metal Generally metals are solid but exception is Mercury Metals are hard but exceptions are Sodium and Lithium Metals have lustre (can reflect light) but exception is Sodium Metals are malleable  (can be hammered into thin sheet) Metals are ductile (can be drawn into wires) Metals are good conductor of heat...

How to write Chemical Formulae for Compounds

How to write Chemical Formulae for Compounds

Hello Viewers: Today we are going to talk about How to write Chemical Formulae for Compounds.  We will go through briefly about symbol, Formula, and Valency and then dig deeper in to each of these.  So let us get started - Symbol It is the abbreviation of English or Latin name of element represented by first letter or first letter in capital with any other letter in small Eg.  H, Fe, C, Cl Formula It is the abbreviation of the molecules represented by symbols and numericals. Eg.  H2, H2O Valency It is the combining capacity of an element with the other element is known as valency and it is determined by the number of hydrogen or chlorine atoms that will combine with one atom of element Eg.  CH4 - methane.  Here one atom of carbon is combined with four atoms of hydrogen.  Valency of carbon is 4   English Name           Latin Name          Symbol               Valancy Sodium                   Natrium                  ...

Elements, Compound and Mixture

Elements, Compound and Mixture

Hi viewer: As we already know that this world is made of matter or substance, which can be further categorized into element, compound and mixture or other words we can say what ever thing we are watching is either element, compound and mixture.  So today we will discuss about the very elementary idea of element, compound and mixture Element On analysis no new substance is formed Eg. Iron, Mercury and Oxygen   Compound When two or more elements combine together in a definite ratio to form a new substances where the individual properties of the elements are completely lost Eg. FeS, CS2 and CO2   Mixture: When two or more substances combine by mere blending in any ratio to form a substance where the individual properties of the substances are not lost completely. Eg.  Any alloy, sand , water and air. Lemonade is a mixture where solid, liquid and gas are present   Properties of compound 1.  A Compound is always homogeneous They are formed in a definite ratio by weight They...
