What are the chemical phenomena in daily life?

1.Steel rust 2Aluminum and copper wires cannot be connected together in electrician operation3

Food rots and spoils4Soda 5Gas etc. combustion6

Detergent decontamination 7Thunderstorm Crops 8When cooking fish, add wine and vinegar (because vinegar and wine react to form esters, which is fragrant)9

Zinc is embedded in the hull of the ship. 10.Gypsum dot tofu 11

The estuary of the river is easy to form a delta (because the river water is colloidal and the seawater is the electrolyte, and the colloids will accumulate and sink when the two meet, thus forming a delta.

12.Ammonium chloride is used as solder 13Disinfectant 14Different brands of inks should not be mixed15Bleaching powder.

16.Set off fireworks.

Rust (iron, steel, copper, etc.) batteries (lithium batteries, automotive acid lead batteries, zinc-manganese batteries, hydrogen batteries, etc.) food (alum in fritters, natural powder yeast in noodles, etc.) combustion (combustion of liquefied gas, natural gas, coal) cleaning (scale, cleaning of impurities on various pots) disinfection (TD, 84, potassium permanganate, pesticides) are enough for 15 These problems are best to use their own brains, which are necessary in life We are living in a physical, chemical, and biological experimental environment.

(1) The food is digested by stomach acid, (2) Smoking cigarettes, (3) Lighters make flames, (3) Fireworks are set off during the New Year, (4) Kerosene lamps are lit, (5) Food is spoiled, (6) Petroleum liquefied gas is ignited, (7) Fruit surface is sterilized with 84, (8) Washing the range hood with super strong range hood detergent (9) Organic fertilizer is brewed, (10) Soap is decontaminated.

Too much.

Iron rusts; Burn; a range of plant reactions (e.g. photosynthesis); Fire extinguisher; the generation of oxygen in the oxygen tank; digestion of food; electrode reaction of the battery; ......I can't think of it.

The oxidation of apples, the reaction of vinegar with baking soda to produce bubbles, the burning of candles or alcohol, the steaming of rice, the brewing of wine, the alkali of the dough, the rusting of iron, the charging and discharging of electric vehicles, etc.

1. The reason why the non-stick pan does not stick to food is because the bottom of the pan is coated with a special substance: "Tefuron", whose chemical name is PTFE, commonly known as plastic king.

2. After strenuous exercise, I feel soreness all over my body, which is because of the increase in lactic acid in the muscles.

3. After the frost falls, green vegetables, radishes, etc. taste sweet, because the starch in green vegetables is hydrolyzed under the action of enzymes in plants to generate: glucose.

4. The reason why the authentic handwriting of ancient calligraphers in China can be preserved to this day: the use of ink or carbon ink makes the handwriting not fade for a long time, because the chemical properties of carbon are stable.

About the combustion of substances

1. Light two candles of different heights, cover them with a beaker, and extinguish the high candle first, because the carbon dioxide gas generated has a higher temperature, rises, and then fills the entire bottle from top to bottom, so when a fire occurs indoors, the mouth and nose should be blocked with a wet towel and bend over to escape from the fire area, and the way to escape from the forest fire is: use a wet towel to block the mouth and nose and escape against the wind.

2. In order to ensure safety, helium can be used to fill balloons in celebrations, not hydrogen.

There are so many chemical phenomena in everyday life that the list goes on:

1. The iron trapped state will rust in the humid air;

2. Charcoal can be burned in the air;

3. Tyndall effect in the woods;

4. Plants can photosynthesize;

5. Baking soda in the kitchen will produce bubbles when it comes into contact with vinegar;

6. When hydrogen peroxide cleans the wound, bubbles will be generated;

7. When the cola is opened, it will bubble.
