1, photosynthesis.
Plants convert carbon dioxide and water into food (glucose) and oxygen through photosynthesis. This is the most common and important chemical reaction in daily life, because through this reaction, plants produce food for themselves and animals and convert carbon dioxide into oxygen.
The reaction process is as follows: 12h2o+6co 2+ sunlight → (reacting with chlorophyll) C6H 12O6 (glucose) +6o2+6o2.
2. Cell respiration.
Contrary to photosynthesis, the reaction process of cell respiration is to combine energy molecules with inhaled oxygen to release energy, carbon dioxide and water needed by cells. The direct energy source that cells can use is a chemical energy called ATP.
The general equation of cellular respiratory response is: c6h 12o 6+6o 2→6 CO2+6H2O+ energy (36ATPs).
3. Anaerobic breathing.
Unlike aerobic respiration, anaerobic respiration describes a series of chemical reactions that enable cells to obtain energy from complex molecules in an anaerobic environment. In life, through the anaerobic respiration and fermentation of yeast and bacteria, ethanol, carbon dioxide and other chemicals will be produced to make delicious cheese, wine, beer, yogurt, bread and other foods.
The reaction process is as follows: c6h 12o 6→2ch2 H5 oh+2co 2+ energy.
Step 4 burn.
I believe everyone is familiar with this. Whenever you light a match, make a fire or barbecue, you will see a bright flame beating. There are many combustion reactions. For example, some chemical reactions in fireplaces and gas stoves are propane combustion reactions.
The general process is as follows: C3 h8+5 O2→4H2O+3 CO2+ energy.
5. rust.
Over time, iron will turn red, and this flaky coating is called rust. This is an example of an oxidation reaction. Copper rust and silver discoloration that form copper surface in daily life belong to this category.
The chemical equation of rust is as follows: Fe+O2+H2O → Fe2O3 xh2o.
