[** General symptoms **: May show signs of anesthesia, fatigue, blurred vision, headache, etc.] 3. ** Skin **: When in contact with the skin, due to the corrosive nature of the resin, it may cause local pain, similar to a prickling or burning sensation. The skin of the contact area may become red, blisters, peeling, etc. 4. ** Respective symptoms **: Inhaling the vapor of the carbolic acid may cause irritation of the respiratory tract, such as coughing and breathing difficulties. In terms of chemical reactions, the reaction of the ester of carbolic acid: 1. ** Substitution reaction **: The substitution reaction with concentrated Bromine water produces 2,4,6-tribromopheol, and the nitration reaction with concentrated Nitric acid produces 2,4,6-trinitrotoluenol; while the substitution reaction of pure Bromine with iron as a catalyst and concentrated Nitric acid with concentrated Sulfuric acid as a catalyst can only produce Bromolene, which means that the substitution reaction of the two is easier than that of the two. 2. ** Reaction related to acid **: Acid is weakly acidic and can react with alkalites. For example, it can react with soda to form sodium-substituted alcohol and water (PhO + NaOx → PhONa + Bi H O). The acidic property of the acid is between the two levels of carbonation and cannot react with weak bases such as NaHCO. The reaction of sodium-substituted alcohol and carbon dioxide can form the reaction of the acid and the hydrogen carbonate-substituted alcohol. The reaction phenomenon is that white turbid liquid appears in the solution after carbon dioxide is added. 3. ** Color reaction **: There is a color reaction in the reaction of the ester. 4. ** Polycondensation reaction **: Polycondensation reaction can occur in the presence of a catalyst.

What are the reactions and symptoms of the baby eating vermicelli?
Babies who eat vermicelli may have the following reactions and symptoms: ** 1. Normal reaction ** 1. ** Adapted well ** - When the rice flour was added properly, the baby could digest and absorb it normally. Generally, after six months, the baby's digestive system was relatively mature and could better adapt to the complementary food of rice flour. Rice flour could provide nutritional supplements other than breast milk or milk powder to meet the growth and development needs of the baby. 2. ** Appetite related ** - If you add the vermicelli at the right time (such as starting from five and a half months to six months, choose to add it at noon) and add it according to the appropriate method (such as pouring 30ml of warm water first, then adding a spoonful of vermicelli and stirring it into a paste), the baby may accept the vermicelli normally and have a normal appetite. Gradually increasing the amount of vermicelli over time can also adapt well. ** 2. Bad symptoms ** 1. ** Vomiting ** - This may be related to the baby's interest in food and digestive ability. Subjectively, some babies would spit out the noodles if they didn't like the taste. There were also some babies who had weak digestive ability and poor digestive function, causing them to vomit. Generally, after four and a half months, if the baby showed obvious interest in adult food and began to add complementary food, if the dosage was too much, the baby might also vomit. However, after six months, the rice flour would usually be digested better and the vomiting would decrease. 2. ** Allergies ** - Although vermicelli was a food that was less likely to cause allergy (because it was usually made from rice, very few people were allergic to rice), there were still babies who would develop allergic symptoms. In the case of intestinal allergy, after the intestinal mucus comes into contact with the vermicelli (allergy), there may be edema and oozing. The baby will have stomachache, show irritability and cry non-stop, which will happen every time he eats vermicelli. Some babies will vomit or diarrhea. After eating vermicelli, they vomit, pale, weak, and have diarrhea. It is easy for family members to mistake it for inflammation or diarrhea. There might be scattered papule-like rashes on the skin. If food allergy is suspected, it can be confirmed by an allergy test or food tolerance test. 3. ** Constipated ** - There were three possible causes of constipation. First, the iron content of rice flour was relatively high; second, eating too much would cause the intestines to not adapt to it. After adding complementary food, the intestines needed to be adjusted and adapted. If the amount of rice flour was too much at one time or a day, it was easy to have constipation; third, there was less dietary-fiber. Pure rice flour had less dietary-fiber. If one ate too much rice flour, it might also cause constipation. 4. ** Indigestion ** - If the vermicelli was made thicker, the baby might have indigestion after eating it, which would hinder the baby's normal development. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Can methyls react with bromic water?
It can react with water. The hydrogen atoms in the ortho-and para-positions of the aromatic ring were more active due to the alcoholic group in the methyol, which made it easy for substitution reactions to occur. When it reacted with bromic water, the hydrogen atoms in the ortho-and para-positions of the alcoholic group could be replaced by the bromic atom, and the reaction would produce a white deposit. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
