How can balance Chemical equation

Chemical reaction

  • How can balancing the Chemical reaction 

  • Definition:-

  • A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side.


  • The coefficients next to the symbols and formulae of entities are the absolute values of the stoichiometric nu



About 

A chemical equation consists of the chemical formula of the reactants and the chemical formula of the products
. The two are separated by an arrow symbol ({ usually read as "yields") and each individual substance's chemical formula is separated from others by " + " seen.


As an example, the equation for the reaction of  hydrochloric acid (HCl) with sodium (Na) can be denoted:


  • eg.  2 HCl + 2 Na → 2 NaCl + H2

  • This equation would be read as "two HCl plus two Na yields two NaCl and H two." But, for equations involving complex chemicals, rather than reading the letter and its subscript, the chemical formulas are read using IUPAC nomenclature. Using IUPAC nomenclature, this equation would be read as "hydrochloric acid plus sodium yields sodium chloride and hydrogen gas."


  • This equation indicates that sodium and HCl react to form NaCl and H2. It also indicates that two sodium molecules are required for every two hydrochloric acid molecules and the reaction will form two sodium chloride molecules and one diatomic molecule of hydrogen gas molecule for every two hydrochloric acid and two sodium molecules that react.

How can react atom and electron

Atom is cutable partical ,but atom subatomic particles election,proton and neutron परमाणु वियोज्य कण नहीं है, बल्कि परमाणु उपपरमाण्विक कण इलेक्ट्रॉन, प्रोटॉन और न्यूट्रॉन हैं An  atom  is the smallest constituent unit of ordinary  matter  that constitutes a  chemical element . Every  solid ,  liquid ,  gas , and  plasma  is composed of neutral or  ionized  atoms. Atoms are extremely small; typical sizes are around 100  picometers  ( 1 × 10 −10  m , a ten-millionth of a millimeter, or 1/254,000,000 of an inch). They are  so small  that accurately predicting their behavior using  classical physics  – as if they were  billiard balls , for example – is not possible. This is due to  quantum effects . Current atomic models now use  quant...

Atomic number

Atomic number Atomic number  Definition :-  Atomic number is the number of protons in nucleus. eg. Helium About  explanation of the superscripts and subscripts seen in atomic number notation. Atomic number is the number of protons, and therefore also the total positive charge, in the atomic nucleus. The  Rutherford–Bohr model  of the  hydrogen atom  ( Z  = 1 ) or a hydrogen-like ion ( Z  > 1 ). In this model it is an essential feature that the photon energy (or frequency) of the electromagnetic radiation emitted (shown) when an electron jumps from one orbital to another be proportional to the mathematical square of atomic charge ( Z 2 ). Experimental...
