write about 10 examples of chemical reactions which happen naturally
Answers
reaction occurs as : 6CO2 + 6 H2O + sunlight → C6H12O6 + 6CO2
2) Respiration: While respiration, glucose present in the blood reacts with the oxygen to form carbon monoxide and water, this an exothermic reaction.
reaction occurs as : C6H12O6 + 6CO2 → 6CO2 + 6 H2O + energy
3) Anaerobic respiration by bacterias, yeast: This is harnessed for fermentation to produce ethanol, carbon dioxide and other chemicals which are used in the making of cheese, wine, beer, yoghurt, bread, etc.
The reaction occurs C6H12O6 → 2C2H5OH + 2CO2 + energy
4) Combustion: Burning a candle, build a fire or light a grill are the examples of the combustion reaction, the energetic molecules are combined with oxygen to produce carbon dioxide and water.
The reaction occurs C3H8 + 5 O2 → 4 H2O + 3CO2 + heat energy
5) Rust: Iron articles develop a red-brown flaky coating called rust. Corrosion is an oxidation reaction. Also, other metals like copper and silver form their oxides over the time.
The reaction of rusting of iron occurs Fe + O2 + H2O → Fe2O3.xH2O
6) Batteries: these are examples of electrochemical redox reactions.
Oxidation and reduction are occurring simultaneously.
7) Digestion: There are thousands of chemical reactions are taking place during digestion. The hydrochloric acid apresent in the stomach is breaks the comlpex food materials to form simple compounds during digestion.
8) Soap and detergents: Soaps and detergents are bind the oily and dirty stains with the soap molecule so that these stains are get remove.
and detergents acts as a surfactant and rinse away the dirt molecules.
9) Acid base reactions: The nature of toothpaste is basic hence it neutralise the acid which is produced by the bacterias present in the mouth and prevent our teeth from decay.
10) Baking : While baking we use backing powder and vineger which on heating produces CO2 so that our cakes befuffy and soft.
The reaction occurs CH3COOH + NaHCO3 → CH3COONa + H2O + CO2
Answer:
1. Rusting
Rusting is an oxidation process that occurs as a result of an oxygen-induced reaction. It produces a flaky brown layer that collects on iron surfaces.
Fe + 3O₂+ xH₂O Fe₃O₄ xH₂O
2. Digestion
When we eat something, a chemical reaction occurs to digest it at the same time. Digestion is a complex process that involves thousands of chemical reactions.
3. Photosynthesis
Plants, like humans, undergo a variety of chemical reactions, including photosynthesis, which converts carbon dioxide and water into plant food - glucose and oxygen. It is one of the most important chemical reactions because it produces oxygen.
6 CO₂ + 6 H₂O + light → C₆H₁₂O₆ + 6 O₂
4. Reactions of Detergents and Soaps
When you use detergent or soap, a chemical reaction occurs.The soaps form a lather through chemical reactions.
5. Aerobic Cellular Respiration
Aerobic respiration produces water and chemical energy in the form of ATP, adenosine triphosphate, through a chemical reaction between oxygen and glucose.
C₆H₁₂O₆+ 6O₂ → 6CO₂ + 6H₂O + energy (36 ATP)
6. Anaerobic Cellular Respiration
Anaerobic respiration occurs primarily in the absence of oxygen and produces less energy than aerobic respiration. Fermentation occurs when anaerobic respiration occurs in microorganisms.
7. Acid-Base Reactions
Acid-base reactions occur when an acid . The reaction of vinegar and baking soda to form water, sodium acetate, and carbon dioxide gas is the best example of this.
NaHCO₃ + HC₂2H₃O₂ → NaC₂H₃O₂ + H₂O + CO₂
8.Combustion
Combustion is the process in which oxidation of a material occurs when it reacts with heat and oxygen.
C + O₂ → CO₂
9.Cooking
The process of cooking is a chemical reaction as which new products are made from the ingredients by using heat.
10.Batteries
Batteries are an important past of daily life. The function of them is a chemical reaction.
