Q: Are the asphalt and peat kinds of vegetables have heavy metal?
Asphalt and its flue gas on the skin and mucous membranes are irritating, phototoxic and carcinogenic effects. China's three major asphalt toxicity: coal tar pitch> shale asphalt> petroleum asphalt, the former two are carcinogenic. Asphalt main skin lesions are: phototoxic dermatitis, skin lesions limited to the face, neck and other exposed parts; black disease, skin lesions are often symmetrical distribution in the exposed parts, was flaky, brown - dark brown - brown black; Acne; verrucous vegetation and heat burns caused by accidents. In addition, there are dizziness, head swelling, headache, chest tightness, fatigue, nausea, loss of appetite and other systemic symptoms and eye, nose, throat irritation symptoms.
Q: The main role of sugar?
Like polysaccharides can be used as storage of nutrients (such as starch and glycogen) or as animal exoskeleton and plant cell cell walls (such as: chitin and cellulose); the other is like a five carbon aldehyde (Such as ATP, FAD and NAD) are also the backbone of some genetic material molecules (such as RNA). Many of the derivatives of carbohydrates are also associated with the immune system, fertilization, prevention of disease, blood coagulation and growth have a great association.
Q: Carboxylic acid and alcohol can react, is it necessary to have certain conditions, if the conditions can not reach, is not it can not respond?
The need for catalyst, such as the book of concentrated sulfuric acid heating,
Q: Is the oxygen derivative of the hydrocarbon a non-methane total hydrocarbon?
What is the total hydrocarbon for non-methane? Non-methane total hydrocarbons generally refer to all volatile hydrocarbons other than methane (which are predominantly C2 to C8), abbreviated NMHC
Q: Comparison of Solubilization of Benzene and Its Derivatives
The chemical properties of benzene are: under certain conditions, benzene can be with hydrogen, bromine, concentrated nitric acid, concentrated sulfuric acid and other substances chemical reaction, benzene can also be generated in the air combustion of carbon dioxide and water. I hope my answer can be helpful for your study!
Q: What is a derivative?
Derivative refers to a simple compound in the hydrogen atoms or atomic groups replaced by other atoms or atomic groups derived more complex products
Q: Benzene derivatives are named from small groups to large groups or from large to small. The following three examples contradict each other ah!
The first should be called p-ethyl toluene, 2,3 pairs, should start from small groups.
Q: What kind of carbohydrates?
carbohydrate: common with sucrose, maltose, lactose in the diet mainly in the form of starch, dextrin and glycogen in the form of sugar in the two sugar from a molecule of glucose and a molecule of fructose Is the most commonly used additive in sweets, pastries and beverages, and sucrose is essentially free of other nutrients in addition to the supply of maltose, which consists of two molecules of fructose, consisting of one molecule of glucose and one molecule of galactose.
Q: The difference between methanol fuel oil and alcoholized oil
Change the smart car dual fuel control can be pure methanol and the whole solution
Q: Such as the title, the personal feeling of chemical transliteration of Chinese transliteration can be done so easy to write, weird name in addition to keep the high point, no good, but rather affect the people's understanding of medicine and memory, contrary to the text to facilitate the exchange of memory Original intention
The title as a Chinese people are not proud of it Do not let you change the way back? Japanese back a element you a cycle almost finished finished ok Chinese can also sideways back to the back of foreign chemistry can cycle table How much is the back? Chinese people want to back half a day to solve the ok
