• Potassium chlorate heated.  .

2KClO_{3  ----- >} 2KCl + 3O₂ .

Potassium chlorate when heated it slowly decompose to form potassium chloride and in this process Oxygen gas is liberated.

• Oxidation reaction  

Magnesium ribbon burns in air

2Mg + O₂  ------ > 2MgO

Magnesium ribbon burns in ai to form white coloured magnesium oxide.

~~•❅••❅•~~

• Carbon burn in air  

C + O₂ -----> CO₂ 

Carbon burn in air,,it combines with oxygen to form carbon dioxide gas.

●┈┉꧁●꧂┉┈●

• Heat is provided to magnesium hydride. 

MgH₂ ----- > Mg + H₂  

Magnesium hydride when heated elemental magnesium forms and hydrogen gas is liberated._.

• _{Suitable heat is given to ethane.} 

CH ₃ -CH₃ ----- > CH ₂ = CH₂  + H₂      

When ethane is heated at high temperature in the presence of a platinum catalyst then ethane is converted into ethene and hydrogen gas is liberated.

• Ethyl alcohol is reacted with acidified potassium dichromate

CH₃ - CH ₂ – OH ----- > CH₃ - COOH + H₂O

Ethyl alcohol is reacted with acidified potassium dichromate to form acetic acid.

• Potasium dichromate is reacted with sulphuric acid

K₂Cr₂O₇ + 4H₂SO₄ ----- > K₂SO₄ + Cr₂ (SO₄)₃ +4H₂O + 3 [O]

Potasium dichromate is reacted with sulphuric acid to form potassium sulphate, Chromium sulphate, water and nascent oxygen is formed.

●┈┉꧁●꧂┉┈●

• Potasium paramagnet is reacted with sulphuric acid

2KMnO ₄ + 3H ₂ SO ₄ ----- > K₂SO ₄ + 2MnSO ₄ + 3H₂O + 5 [O]

Potasium paramagnet is reacted with sulphuric acid to form potassium sulphate,  Manganese sulphate, water and nascent oxygen.

• Acidified potassium permagnet is oxidized by ferrous sulphate 

2KMnO₄ + 10FeSO₄ + 8H₂SO₄ ----- > K₂SO₄ +2MnSO₄ + 5Fe₂(SO₄ )₃ + 8H₂O.

Acidified potassium permagnet is oxidized by ferrous sulphate to form potasium sulphate, Manganese sulphate, ferric sulphate.

●┈┉꧁●꧂┉┈● 

• Hydrogen gas is passed over copper oxide 

CuO + H_{2  ------- >}  Cu + H₂O

Hydrogen gas is passed over copper oxide to form a copper element. 

●▬▬๑۩ ۩๑▬▬●

• Hydrogen sulphide / suifide gas react with Sulphur dioxide gas.

2H₂S + SO₂  ------- > 3S + 2H₂O

Hydrogen sulfide gas react with Sulphur dioxide gas to form elemental sulphur. / sulfur

 

●┈┉꧁●꧂┉┈●

•  Manganese Dioxide react with hydrochloric acid 

MnO₂ + 4 HCl ----- >  MnCl₂ + 2H₂O + Cl₂

Manganese dioxide react with hydrochloric acid to form  Manganese chloride and chlorine gas is liberated.

• Iron is exposed to air. 

  How iron is rusted.

  How Iron is corroded?

 2Fe ³⁺ (aq) + 4H₂O(l) ----- > Fe₂O₃ .H₂O(s) + 6H⁺(aq)

When iron exposed to air oxidation of iron takes place this is called corrosion. The radish colour formed on the surface of iron is called rust..

दुःख हे कधीच दागिन्यांसारखं मिरवू नका,

वाटू शकलात तर आपला आनंद वाटा. 

                   लोक तुमच्याकडून आनंदाची अपेक्षा करतात, 

        कारण दुःख त्यांच्याकडे पण भरपूर आहे !!!

      आपला दिवस आनंदी जावो.🎷
