Enjoying life is inseparable from chemical knowledge, and the home kitchen is a small world of chemi

(1) The main source of clean energy in the home is electricity

So the answer is: electrical energy;

2) Rice is most susceptible to mildew when the temperature is 20 -38 and the relative humidity reaches more than 80%-85%, so we store rice in a low temperature and dry place

So the answer is: low temperature drying;

3) There are three principles of fire extinguishing: removing combustibles, isolating oxygen or air, reducing the temperature of combustibles to the ignition point, if the oil in the pot is on fire, the fire extinguishing measures that can be taken are to cover the pot, isolate the air or quickly add vegetables, reduce the temperature of the oil to the ignition point, etc

So the answer is: cover the pot; Isolate the air;

4) Due to the different tastes of the two, the method of tasting can be used, the salty is salt, and the astringent is soda ash;

Therefore, the answer is: tasting, salty is salt, astringent is soda ash;

5) 2) The Ministry of Health promotes the use of fortified iron-fortified soy sauce The "iron" here refers to the element

So the answer is: elements;

6) Activated carbon has adsorption, can adsorb pigments and odors, and can decolorize brown sugar into white sugar by using the adsorption property of activated carbon

So the answer is: adsorption

1) The electricity used in the home is a clean energy source;

2) The main components of rice and noodles are starch composed of carbon, hydrogen and oxygen;

Because rice is most susceptible to mildew when the temperature is 20 38 and the relative humidity reaches more than 80% 85%, aflatoxin is produced, so the storage method of rice is to store it in a low temperature and dry place;

3) Liquid vegetable oil and solid animal oil are collectively called oils, and their main role in the human body is to provide energy;

According to the burning conditions, if the oil in the pot is on fire, the fire extinguishing measure that can be taken is to cover the pot, and the principle of fire extinguishing is to isolate the air;

4) Iodine is an important component of thyroid hormones, and iodization in table salt can effectively prevent goiter; Iron is an important component of hemoglobin, and the popularization and use of iron-fortified soy sauce has significantly reduced the incidence of anemia in children.

5) Cucumber is rich in vitamin C, because vitamin C is more stable in pH 5 and low temperature environment, in order to reduce the loss of vitamin C, the best way to eat cucumber is to add vinegar and cold dressing;

6) Soaking and rinsing vegetables with alkaline solution can reduce the toxicity of pesticides remaining on vegetables, so it is best to add an appropriate amount of alkaline solution when soaking vegetables, such as soda ash, sodium bicarbonate, etc.;

7) Activated carbon has adsorption, can adsorb pigments, and can decolorize brown sugar into white sugar;

8) Where there is air, the food is easy to be oxidized and deteriorated, so vacuum packaging is adopted

Therefore, the answer is: (1) electricity, natural gas, coal gas, liquefied petroleum gas, etc. (one can be answered).

2) carbon, hydrogen, oxygen; Dry place at low temperature

3) provide energy; Cover the pot; Isolate the air (other correct answers are acceptable).

4) goiter; Anemia

5) Add vinegar and salad

6）Na2CO3

or NaHCO3

7) Adsorption

8) Remove oxygen (or air) to prevent slow oxidation (if the answer is reasonable, it will be scored).

(1) The main clean energy in the home is natural gas

2) If the oil in the pot is on fire, the fire extinguishing measures that can be taken are to cover the pot, and the principle of fire extinguishing is to isolate the combustibles from the air. Isolate combustibles from the air

3) To distinguish between salt and soda ash, feasible methods: take a small amount of samples in the test tube, add a small amount of vinegar, if the bubbles are soda ash, no phenomenon is salt Therefore, fill in: take a small amount of samples in the test tube, add a small amount of vinegar, if the bubbles are soda ash, no phenomenon is salt

4) For the health of the whole people, the Ministry of Health promotes the use of fortified iron-fortified soy sauce The "iron" here refers to the element Therefore, fill in: element

5) The plastic packaging bags commonly used in the kitchen are mainly made of polyethylene or polyvinyl chloride as raw materials, and the plastic that cannot be used as packaging food is polyvinyl chloride

6) The main components of white sugar and brown sugar are sucrose Using the adsorption of activated carbon, brown sugar can be decolorized into white sugar
