some basics concepts of chemistry #11 Must subscribe this channel 👆👆 Molecule: a molecule is the ultimate particle of an elements or compound which can  exist in free state and possesses all characteristic  properties of that substance. Atom:   An atom is the ultimate particle of an element of an element which can take part in a chemical reaction.  Atom          Molecules are of  two  types 1. Elementary                       2. Compound  1. Elementary molecules are  composed of atoms of same elements,  e.g., hydrogen(H 2 )  chlorine(Cl 2 )...  etcetera  Oxygen (O 2 ) 2. Compound molecules are composed of atoms of more than one type of element   e.g., HCL, CO 2 ,  NH 3  ... etcetera  NH 3  molecules  Note:  The Atoms of noble gases and  metals can exist in free state.

Reality of modern Era.

  Today is the Birthday  of my friend named DANISH.    everyone is wishing him on the occasion of his birthday,  all the people who relate to Danish is wishing, keep danish's pic in their status,  profile.  but.... okey, I also wish him but I didn't put his pic in status, profiles, and all,  Also I was the late wisher....    however According to danish I become a best wisher ever. Do you know why??    Because I just call him and sung the birthday song for him.    Here in this story you can understand the reality of modern Era.

Modern atomic theory

some Basics concepts of chemistry  #10 Modern Atomic theory. 👇👇To watch video hindi lecture. 👇👇 https://youtu.be/GtoszO3Mm9Q The main points of modern atomic theory are--- (1)  According to modern atomic theory, An Atom is no longer indivisible. ---Atom is composed of number of subatomic particles of which protons, electrons and neutrons are important. (2). Atom of the same elements may not be Identical in mass.  After the discovery of Isotopes  has been proved that Atoms of same elements may have Atoms of different  masses. e.g    (3). Atom of different elements usually combine together in a fixed simple whole number  to form molecules,  But several of compounds are known in which atoms do not combine together in a fixed simple whole number ratio, called non-stoichiometric compound.  e.g FeO 0.93 (4).Atoms are no longer considered indestructible.

Dolton's Atomic Theory ---constitution of matter

Image
  Some Basic  concepts of chemistry  #09 To watch video  https://youtu.be/IR-2s_w6kEY Postulates of Dolton's atomic theory : 1. Matter is composed of a large number of minute discrete particles Called Atoms 2. Atoms can neither be created nor be destroyed in a physical change or chemical reactions.  3. Atoms of the same element are Identical with each other in mass, size,  shape, and other properties.  4. Atoms  of different elements are different in all respects  i.e, they differ in mass, size, shape and properties.  5. when atoms of different elements combine with  one another to form  a compound Atom ( later on called molecules),  they do so in simple whole number ratios. Limitations of Dolton's Atomic theory: Atom is no longer considered to be  indivisible.  It has now  been proved that an atom is composed of smaller particles like electrons, protons,  neutrons, positrons  etcetera. Also  ...

Gay Lussac's law of gaseous volumes

law of reciprocal or equivalent proportions

Image
some basic  concepts  of chemistry #07 Laws of chemical combination. 4 . The law of reciprocal or equivalent proportions:   It's stated as    " The ratio in which two elements combine separately with a fixed mass of the third element is either the same or is a simple whole number multiple of the ratio in which these elements combine with each other." let's understand this law simply, that the ratio of masses of B and C which combine separately with a fixed mass of third element A, is either the same as or some simple multiple  of the ratio of masses of B and C combine with each other. 

Law of multiple proportions

Image
 Some Basic concepts of chemistry  #06 law of chemical combination  3.  Law of multiple proportions:  the law states that--        "when two elements combine to form two or more compounds,  the different masses of one of the elements, which combine with a fixed mass of the other elements, bear a simple ratio of whole numbers to one another."  To watch lecture https://youtu.be/SCTVr1woAjU  example👇👇👇 Limitations: the law of multiple proportions doesn't  apply to such compounds, e.g in butane( C 4 H 10 ), pentane (C 5 H 12 ) and hexane(C 6 H 14 ), it is found that 12 parts by mass of carbon in each case combine with 2.5 : 2.4 : 2.33 parts by mass of hydrogen respectively.  The mass ratio of hydrogen is not bear a simple ratio. 

Law of definite proportions

Image
Some basic concepts of chemistry #05   Law of chemical Combination.  2. Law of definite or constant proportions : it's states that ,   "  The same compound always contains the same elements combined together in the same fixed (definite) proportion by mass and its composition is independent of the method by which it is prepared. "   To understand this law simply, you have to remember the things that is  - No matter what is  the source of the compound, rather it matter only about the elements of the compound. yess dude😂😂, there is also limitations of the law of constant proportions. Limitations:-    let's see the  example,  ethyl alcohol and dimethyl ether are found to contain the same elements( like carbon, hydrogen,  and oxygen) which are combined in the same mass ratio.        C 2 H 5- OH  👉👉👉        C:H:O = 12:3:8        CH 3 -O-CH 3  👉👉👉  ...

Law of conservation of mass

Image
Some basic concepts of chemistry  #04 Laws of  chemical combination . Law of conservation of mass :   It states  that,    " Matter can neither be created nor destroyed as a result of any chemical or physical  change "            but this law  is not absolutely true,  there is limitations of the law of conservation  of mass. Limitations :   according to modern theory of Radiation, the thing is  mass and energy are inter convertible  according to einstein equations ( E=mc²).           A  chemical reaction which is accompanied by an emission of energy  usually in the form of heat, will be attend with loss of mass=E/c².   As c is very large, the loss of mass becomes insignificantly small. thus the law of conservation of mass holds good for ordinary chemical reactions.  but in nuclear fission/fusion enormous amounts of energy  is...

what is the difference between Mixture and compound?

  M i x t u r e Comp ound     (1)   A mixture results when two or more  elements or compound or both  are mixed in any proportion  by mass.  (1)  In a compound the ingredients are present in a fixed proportion by mass.   (2)  A mixture the ingredients  may lose their physical properties but chemical properties remains same.  (2) The chemical properties of the constituents are totally changed, and new properties  are developed.    (3) A mixture may be homogeneous or heterogeneous.   (3) A compound  is always homogeneous.    (4) During the preparation of mixture, thermal change may or may not occur.  (4)  During the formation of compound,  there is always a thermal change.   https://youtu.be/v1I3wi3lBYk          watch on YouTube to understand                 I know you guys  so...

Basic Concept Of chemistry.  #01 Anything that occupies space, and having mass and inertia is called Matter. classification of matter:- [A] physical classification        [B] chemical classification [A] physical classification:- Solid state :    In solid state, matter has definite shape and definite volume.  e.g, metal, salt, suger etcetera  Solid state Liquid  state : In liquid state, matter does not have definite shape but  have definite volume. e.g, water, milk, oil, etcetera  Gaseous state : In gaseous state,  matter does not have a definite volume or definite shape. It can be compressed and takes the shape of container where it is kept.   e.g, hydrogen, oxygen,  etcetera  https://youtu.be/olxIcjnwFNE  

What is Science?

Image
 Science is nothing but logical interpretation of Nature. science:-      It is the branch of study concerned with observation and formation of general laws chiefly by induction and hypothesis.   The aims of science are:- To attain the thoughts,  through rational thinking after carefully experimenting the facts or data in the laboratory; To develop the ability of concentrating on a problems and to find the solution through qualitative and quantitative approaches; To utilise human and natural resources through the application  of our five senses for the betterment of our future generations; To acquire and disseminate our overall knowledge of nature.   This is the things makes the science interesting,  and bind with our emotions and Love.

    Feelings  during depression      this is now becomes a trend  topic. Before We talked about depression we should know actually what is depression. (I m just only blogging about my experience on this topic) so clearly I m saying that sadness is not a depression.  If you feel sad this will be temporary and after a couples of time you can feel better.  But Due to any emotional  breakdown or any  other cause If you get depressed.  It wouldn't be temporary.  whatever your emotions behind is, will be going in your thoughts all the time. Symptoms :-  while that momentum of life we feel like. butterflies flying in our stomach, The  Intensity  of the feelings concentrate  towards left chest( i.e heart), anxious mind, Frustration, etc. Cure:-  Reading books like a children, consult a Doctor,    Busy yourself in that stuff which you love to do,  Importantly* share all the things which ...

            Peace for Humanity  On May 25, 2020,  George Floyd , a 46-year-old black man, was killed in Minneapolis, Minnesota, during an arrest for allegedly using a counterfeit bill.    when I see this news articles. I felt very  turbulent.   because this article is not only just about murder, killing, rather this is about Humanity.       A white police officer  knelt on floyd neck's  for almost 9 minute while Floyd was handcuffed and lying down in the street, he was begging for his life  and repeatedly said I can't breathe.       here the point is there is a matter of  colour racism which is strongly violence for the  Humanity.  Being Ummati of  prophet Mu hammed (SWS).    we see that, Hazrat Bilal ibn Rabah ( Blackman) considered to have been the first mu'azzin, specially choosen  by our prophet Muhammad (SWS).     ...

Sound of silence

Once time in my childhood when all the neighbours was slept. and I had been talking to my Ammi. &  I used to heard  something   at that time. I didn't know about that sound which I used to heard in silence. and I asked my Ammi:-  are  you listening this sound. What is that?? My Ammi replied:- zhingur ka aawaz h.(Beetle's noise). {Indeed she is right.}     now I M  still observing  that sound in the state of silence.  I found that this sound Intensity  and frequency  changes with respect to silence. ( I don't know yet properly).   Method to listen the sound of silence.   Fazr (morning) time is the best silent time, and just sit, close ur eyes, use ear plug, and stop thinking,  then finally  you'll start listening this sound, and you can feel and only concentrate to feel the sound of silence.  Also You can called this procedure as meditation,   etcetera.
