    जब पहली बोलती फिल्म प्रदर्शित हुई तो उसके पोस्टरों पर निम्नलिखित वाक्य छपे थे, “वे सभी सजीव है, सांस ले रहे हैं, शत-प्रतिशत बोल रहे हैं, अठहत्तर मुर्दा इंसान जिन्दा हो गए, उनको बोलते बातें करते देखो”। इस वाक्य से पता चलता है कि उस फिल्म में अठहत्तर चेहरे थे।

    Laws of Chemical Combination Limitation of “Law of definite proportion” This law does not hold good when the compound is obtained by using different isotopes of the combining elements. 2. John Daltons Atomic Theory Using his theory, Dalton rationalized the various laws of chemical combination which were in existence at that time. However, he assumed that the simplest compound of two elements must be binary. 3. Atoms, Molecules, Ions & Chemical Formula Atom An atom is the smallest particle of an element which can take part in a chemical reaction. It may or may not exist freely. Each atom of an element shows all the properties of the element. Molecule The smallest particle of matter (element or compound) which can exist in a free state. The properties of a substance are the properties of its molecules. MOLECULES OF ELEMENT : The molecules of an element are constituted by the same type of atoms. MOLECULES OF COMPOUND: Atoms of different elements join together in definite proportions to form molecules of compounds. (hetero atomic molecules) ATOMICITY: The number of atoms contained in a molecule of a substance (element or compound) is called its atomic Element Formula Atomicity Ozone O3 3 Phosphorus P4 4 Sulphur S8 8 Oxygen O2 2 Based upon atomicity molecules can be classified as follows. Monoatomic molecules: Noble gases helium, neon and argon exist as He Ne and Ar respectively. Diatomic molecules: Triatomic molecules: SYMBOLS The abbreviation used to represent an element is generally the first letter in capital of the English name of element. Oxygen O Nitrogen N When the names of two or more elements begin with the same initial letter, the initial letter followed by the letter appearing later in the name is used to symbolize the element Barium Ba Bismuth Bi Symbols of some elements are derived from their Latin names ELEMENT LATIN NAME SYMBOL Sodium Natrium Na Copper Cuprum Cu Potassium Kalium K Iron Ferrum Fe Mercury Hydragyrum Hg Tungsten Wolfram W Polyatomic Ion : A group of atoms carrying a charge is as polyatomic ion. Eg. Valency : The number of electrons which an atom can lose , gain or share to form a bond. OR It is the combining capacity of an atom of the element. Chemical Formula : A chemical formula is a short method of representing chemical elements and compounds. Writing a Chemical Formula -CRISS-CROSS rule RULES > All subscripts must be reduced to lowest term (except for molecular or Examples CATION ANION FORMULA NAME Aluminium sulphate Ca Calcium bicarbonate Ammonium chloride Sodium carbonate Magnesium hydroxide Sodium phosphate 4. Mole Concept The mole (mol) is the amount of a substance that contains as many elementary entities as there are atoms in exactly 12.00 grams of The Avogadro constant is named after the early nineteenth century Italian scientist Amedeo Avogadro. GRAM MOLECULAR MASS Gram molecular mass is the mass in grams of one mole of a molecular substance. Ex: The molecular mass of is 28, so the gram molecular mass of is 28 g. ATOMIC MASS UNIT An atomic mass unit or amu is one twelfth of the mass of an unbound atom of carbon-12. It is a unit of mass used to express atomic masses and molecular masses. Also Known As: Unified Atomic Mass Unit (u). MOLECULAR MASS : A number equal to the sum of the atomic masses of the atoms in a molecule. The molecular mass gives the mass of a molecule relative to that of the 12 C atom, which is taken to have a mass of 12. Examples: The molecular mass of is approximately 30 or . Therefore the molecule is about 2.5 times as heavy as the 12C atom or about the same mass as the NO atom with a molecular mass of 30 or (14 +16). 5. Molar Mass & Avogadro Constant

    सहकारी समितियों की भूमिका:
    (i) भारत में विशेषकर देश के दक्षिणी और पश्चिमी भागों में सहकारी समितियाँ खाद्य सुरक्षा में एक महत्वपूर्ण भूमिका निभा रही हैं।
    (ii) सहकारी समितियाँ निर्धन लोगों को खाद्यान्न की बिक्री के लिए काम कीमत वाली दुकानें खोलती हैं।
    उधारणतः तमिलनाडु में जितनी राशन की दुकानें है, उनमें से करीब ९४ प्रतिशत सहकारी समितियों के माध्यम से चलाई जा रही हैं।
    (iii) दिल्ली में मदर डायरी उपभोक्ताओं को दिल्ली सरकार द्वारा निर्धारित नियंत्रित दरों पर दूध और सब्ज़ियाँ उपलब्ध कराने में तेज़ी से प्रगति कर रही है।
    (iv) गुजरात में दूध तथा दुग्ध उत्पादों में अमूल एक और सफल सहकारी समिति का उदाहरण है। इसने देश में श्‍वेत क्रांति ला दी है।

    freedom can be defined in two aspects, that is, absence of constraints and existence of conditions which expand freedom. but freedom has other aspects too. swa means self and raj means rule . so there needs to be self rule. it meant rule of the self and rule over self.
