Answer 1

$\huge{\boxed{\mathcal{\red{CHEMICAL\;REACTION}}}}$

✿ Chemical reaction is defined as the process which leads to transformation of chemical substances from one form to another. In a chemical reaction the substance undergoing transformation called reactant and the new substance that are formed called products.

Example:-

$\bold{1).\;A + B = C + D} \\ \\ \bold{2).\;Mg + O_{2} = MgO}$

$\large{\textsf{\red{\underline{\underline{Types\;Of\;Chemical\;Reaction}}}}}$

$\huge{\boxed{\mathcal{\red{COMBINATION\;REACTION}}}}$

✿ When two or more reactants combine together to give a single product is called combination reaction.

Example:-

$\bold{1).\;CaO + CO_{2}\longrightarrow CaCO_{3}}\\ \\ \bold{2).\;Ca(OH_{2})+CO_{2}\longrightarrow CaCO_{3}+H_{2}O}$

$\huge{\boxed{\mathcal{\red{DECOMPOSITION\;REACTION}}}}$

✿ When a single reactant breaks down into two or more products on application of some form of energy like heat, electrical and light energy is called decomposition reaction.

Example:-

$\bold{1).\;2FeSO_{4}\xrightarrow{\bold{Heat}}Fe_{2}O_{3}+SO_{2}+SOx_{3}}\\ \\ \bold{2).\;2AgCl\xrightarrow{\bold{Sunlight}}2Ag+Cl_{2}}$

$\large{\mathbb{\red{\underline{TYPES\;OF\;DECOMPOSITION\;REACTION}}}}$

$\large{\mathsf{\red{\underline{\underline{1).\;Thermal\;Decomposition}}}}}$

✿ Decomposition in which heat is supplied is called thermal decomposition.

$\large{\mathsf{\red{\underline{\underline{2).\;Electrical\;Decomposition}}}}}$

✿ When a single reactants breaks down into two or more products in the form of electricity is called electrical decomposition.

$\large{\mathsf{\red{\underline{\underline{3).\;Photo\;Decomposition}}}}}$

✿ When a single reactants breaks down into two or more products in the form of sunlight is called photo decomposition.

$\huge{\boxed{\mathcal{\red{DISPLACEMENT\;REACTION}}}}$

✿ It is a displacement in which a high reactive metal displace low reactive element by metal salt solution.

Example:-

$\bold{1).\;Fe+CuSo_{4}\longrightarrow FeSo_{4}+Cu}\\ \\ \bold{2).\;2Al+3FeSo_{4}\longrightarrow Al_{2}(SO_{4})_{3}+3Fe}$

$\huge{\boxed{\mathcal{\red{DOUBLE\;DISPLACEMENT\;REACTION}}}}$

✿ Double displacement reaction is defined as the chemical reaction in which one component each of both the reacting molecules is exchanged to form the products.

Example:-

$\bold{1).\;No_{3}+NaCl\longrightarrow AgCl\downarrow + NaNos}\\ \\ \bold{2).\;FeS+H_{2}SO_{4}\longrightarrow FeSO_{4}+H_{2}S\uparrow}$

$\huge{\boxed{\mathcal{\red{REDOX\;REACTION}}}}$

✿ In Redox Reaction we study about Reduction and Oxidation.

Example:-

$\bold{1).\;CaO + H_{2}O\longrightarrow Ca(OH)_{2}}\\ \\ \bold{2).\;2Mg+O_{2}\longrightarrow 2MgO}$

$\large{\mathsf{\red{\underline{\underline{1).\;Oxidation}}}}}$

✿ Addition of oxygen/electronegative element. Removal of Hydrogen/electropositive element.

$\large{\mathsf{\red{\underline{\underline{2).\;Reduction}}}}}$

✿ Removal of oxygen/electronegative element. Addition of Hydrogen/electropositive element.

Answer 2

$\huge\boxed{Chemical\:Reaction}$

✏Whenever a chemical change occur we can say that chemical reaction occurs .The changes that occurs in our environment /surrounding are known as chemical reaction.

For example :-

✒Respiration in animals

✒Digestion of food

✒Burning of coal

✒Rusting of iron

----------------------------------------------------------------------------------------------------------

Types of chemical reaction :-

$\huge\bold\blue{Combination\:Reaction}$

✒The reaction in which two or more substances combine to form a single product are known as combination reaction

✒For example :-CaO +H2O ------> Ca(OH)2+ Heat

---------------------------------------------------------------

$\huge\bold\green{Decomposition\:Reaction}$

✒A reaction in which a single substance is break down to give two or more substances is called decomposition reaction

✒For example :-2FeSO4 ------->Fe2o3+ So2+ So3

-----------------------------------------------------------------

$\huge\bold\blue{Displacement\:Reaction}$

✒When an element displaces other element from its compound is called Displacement reaction

✒For example :-Zn+Cuso4--------> znso4+Cu

-----------------------------------------------------------------

$\huge\bold\green{Double\:Displacement\:Reaction}$

✒Such reaction in which there is an exchange of ions between the reactants are called double displacement reaction

✒For example :-2NH4Cl + Ba(OH)2------->2NH4OH + BaCl2

----------------------------------------------------------------

$\huge\bold\blue{Oxidation\:And\:Reduction}$

✒Oxidation is the gain of oxygen or Loss of hydrogen. Reduction is a loss of oxygen and gain of hydrogen

✒For example :-2Pbo + C--------> 2Pb + Co2

Pbo is reduced in Pb and carbon is oxidised in Co2

That's what all about chemical reaction ✔✔
