Yes. It was caused by incomplete combustion.
-
There are generally three values of tar, nicotine and carbon monoxide on the cigarette, of which carbon monoxide is purely for the environmental protection department and the health department to get it. It's like car exhaust.
-
It is the amount of carbon monoxide in the substance produced by smoking this cigarette, carbon monoxide is toxic and can bind to hemoglobin, and the purpose of the label is to remind smokers that smoking is harmful to health.

Hello dear, yes.
The smoke released when tobacco is burned contains more than 3,800 known chemicals, most of which are harmful to the human body, including carbon monoxide, nicotine and other alkaloids, amines, nitriles, drunkenness, phenols, alkanes, aldehydes, nitrogen oxides, polycyclic aromatic hydrocarbons, heterocyclic compounds, hydroxyl compounds, heavy metal elements, organic pesticides, etc., a wide range, they have a variety of biological effects, causing various harms to the human body.

1. The photolysis of NO2 in polluted air is the initial reaction of photochemical smog formation.
2. Hydrocarbons are oxidized by free envy good groups such as HO and O and ozone, resulting in the formation of free radicals such as aldehydes, ketones, alcohols, acids, and important intermediate products such as RO2, Teremori Ho2, and RCO.
3. Peroxyl radicals cause the conversion of NO to NO2, and lead to the formation of O3 and PAN.
The ozone, aldehydes, ketones, alcohols, pans, etc. generated in the photochemical reaction are collectively referred to as photochemical oxidants, represented by ozone, so the sign of photochemical smog pollution is the increase in the concentration of ozone brother lead.

It's not about the indicators, but mainly refers to the proportion of volatiles - the semi-bituminous coal you are talking about should be semi-anthracite, that is, it has a high volatile content in anthracite.
Coal is divided into lignite, anthracite, bituminous coal, semi-anthracite.
The flame of anthracite combustion is not obvious, but the calorific value is high, about 8000-8500 kcal kg, bituminous coal is 6000-8900 kcal kg, and the flame of bituminous coal is long, obvious, accompanied by smoke.
Lignite has a low ignition point, is flammable, loose, emits black smoke, and needs to be replaced frequently (if you use it as fuel).
Also, the carbon monoxide problem that my classmates mentioned, I guess you are considering which fuel is safer.
In fact, carbon monoxide is the product of incomplete combustion, mainly depending on the combustion conditions of the fuel, and the amount of carbon monoxide between the two should be almost the same when the oxygen is sufficient. For household coal, anthracite is naturally the best choice.
-
Hemibituminous coal also belongs to bituminous coal.

The harmful components in smoke are mainly: carbon monoxide, nicotine, cigarette tar. There are other substances such as amines, nitriles, drunken, phenols, alkanes, aldehydes, nitrogen oxides, polycyclic aromatic hydrocarbons, heterocyclic compounds, hydroxyl compounds, heavy metal elements, organic pesticides, etc.
Carbon dioxide is not a harmful gas. Because there is also carbon dioxide in the air. We'll all be fine after absorbing it.
-
Mainly carbon monoxide and tar but also nicotine.
-
There is a large amount of carbon monoxide in cigarette smoke, and the binding capacity of carbon monoxide to hemoglobin is 240 300 times greater than that of oxygen, and carbon monoxide is inhaled into the human body to combine with hemoglobin, which seriously weakens the oxygen-carrying capacity of red blood cells, so smoking accelerates blood clotting, and is easy to cause cardiovascular diseases such as myocardial infarction, stroke, and myocardial hypoxia.
1. See if it can be burned; 2. When combusting, the flame is covered with a dry beaker 1 to prove that it is generated without water. (excluding the interference of other gaseous organic compounds) 3. The gas generated by combustion passes into the clear lime aqueous solution, and white precipitates are generated, then the combustion product is carbon dioxide, and the original gas is carbon monoxide. >>>More
No. Carbon monoxide molecules are small and not easily adsorbed; Carbon monoxide is insoluble in water and is not a salt (does not react with acids or alkalis), making it difficult to absorb.
What is Carbon Monoxide? Parse.
Carbon monoxide does not directly destroy the ozone layer, but it can become indirectly damaged by complex reactions in the atmosphere, and the main component of the ozone layer is O3According to the chemical equilibrium, the interconversion formula of O2 and O3 in the atmosphere keeps the oxygen and ozone levels in equilibrium. Carbon monoxide is chemically stable. >>>More
It's nothing. When you find it, you should move it to a place of air circulation and get a lot of fresh air. >>>More
