There were several main mechanisms for solid acid reactions: - In the esterfication reaction, it usually followed the addition-elimination mechanism, the carbonium ion mechanism, and the acyl ion mechanism. - In the conversion reaction, it involves the cracking of the biological mass, molecular rearrangements, oxidization, and dehydration. Solid acid carries out an acid catalyst reaction with the functional groups in the biological mass molecules through its acidic sites to achieve the conversion of the biological mass molecules.

Sulfamic acid was also known as solid sulfuric acid. There was no information about the substance called " solid sulfuric acid ", so it was impossible to determine whether it reacted with the sulfamic acid. The nature of the sulfamate was stable, not easily volatile, and had little toxicity to the body. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Not all reactions between acid, base, and salt were metatheses. In junior high school chemistry, the reaction of acid and metal to form salt and hydrogen, such as 2AI +3H ^SO = AI ^(SO)+3H ^^, this reaction is not a metathesis reaction. Alkali reacted with non-metallic compounds to form salt and water, such as 2NaOx + CO2 = Na Chi CO2 + H Chi O, which was also not a metathesis reaction. The reactions of neutralizing acid and base (acid + base = salt + water), acid and salt (acid + salt = new acid + new salt), base and salt (base + salt = new base + new salt), salt and salt (salt + salt = two new salt), and metal oxide-acid (acid + metal oxide-salt + water) were all metathetical reactions. Moreover, the metathesis reaction had to meet certain conditions. The reagent had to be dissolved in water or acid, and the product had to be either one or two of the three substances of precipitations, gas, and water. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
1. ** Reaction of iron and zincate with enough diluted sulfuric acid (abyssal coordinate is reaction time)** - Reaction rate: According to the order of metal activity, the reaction rate of the reaction between the metal and the diluted sulfuric acid is faster than that of the iron. In the image, the reaction curve for the reaction of the iron was much more inclined than the reaction curve for the reaction of the iron. - Quality of hydrogen produced: According to the chemical reaction equation,<<Mn>+>+<Mn>+>+<Mn>+<Mn>+<Mn Therefore, as the reaction progressed, the final hydrogen mass curve corresponding to iron would be higher than the corresponding curve of the corresponding iron. 2. ** Reaction of iron and zincate with enough diluted sulfuric acid (the horizontal coordinate is the mass of diluted sulfuric acid)** - Reaction rate: Similarly, the reaction rate of the iron is faster than the reaction rate of the iron. - Mass of hydrogen produced: Because the hydrogen atoms in the hydrogen came from the hydrogen atoms in the diluted sulfuric acid, when the diluted sulfuric acid was sufficient, according to the chemical equation, the mass of hydrogen produced by iron was more for the same mass of iron and iron. The mass curve of hydrogen produced by iron was higher than that of the corresponding curve of iron. 3. ** Reaction of an equal amount of iron and zincate with diluted sulfuric acid of the same mass and solute mass fraction (the horizontal coordinate is the reaction time)** - Reaction rate: The reaction rate of the catalyst is faster than that of iron. The curve of the catalyst is higher than that of iron in the early stage of the reaction. - Mass of hydrogen produced: Since the hydrogen atoms in hydrogen come from the hydrogen atoms in the diluted sulfuric acid, the diluted sulfuric acid is small in quantity and has the same mass and concentration. According to the conservation of atoms, the mass of the finally produced hydrogen is the same, so the two curves are finally on the same level. 4. ** Reaction of a sufficient amount of iron and zincate with diluted sulfuric acid of the same mass and solute mass fraction (the horizontal coordinate is the mass of iron and zincate)** - Reaction rate: The reaction rate of the iron is faster than the reaction rate of the iron, and the slope of the curve of the reaction rate of the iron is larger. - Mass of hydrogen produced: Because there is a small amount of diluted sulfuric acid, according to the conservation of atoms, the mass of hydrogen produced is the same, so the two curves are finally on the same level. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
During the reaction of sulfuric acid and sulfuric acid, a large amount of Cl2 and nitronyl chloridewas formed. The color of the mixture darkened, and a large amount of reddish-brown gas (with some yellowish-green) was formed. The solution gradually turned brown, and the amount of gas formed increased. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction of copper sulfuric acid to humans was mainly reflected in the following aspects: - ** Effects on skin and mucus membrane **: - When it comes into contact with the skin, it may cause local ulcers and corrosion of the skin. Long-term exposure to its dust may cause diseases such as allergic rhinoceros and acute bronchitis. The skin of infants and children is fragile and the risk is greater. - If it comes into contact with the eyes or is inhaled, it will irritate the eyes, nose, mouth, throat and other parts, causing diseases such as inflammation and inflammation. Copper Sulphate solution may cause redness and edema when it comes into contact with the oral mucus membrane. - Long-term contact with copper sulfuric acid solution may cause damage to the skin, causing symptoms such as inflammation and acne. Contact with high-concentration solutions may also cause skin pain and redness. - ** Effects on the digestive tract **: - Ingesting copper sulfuric acid by mistake would corrode the digestive tract, causing nausea, vomiting, abdominal pain, diarrhea, and other digestive symptoms. In severe cases, it could lead to liver and kidney damage or even shock, and could also lead to dehydration. - Even if a small amount of copper sulfuric acid was ingested, it might stimulate the gastric and intestinal membranes, causing burns and cramps in the stomach, causing nausea, vomiting, and even vomiting blood and stool blood. In the long run, it might cause cancer, ulcers, and other diseases. - ** Effect on the whole body **: - The human body ingested a certain dose (11 milligrams/kg) of copper sulfuric acid, which could cause poisoning. If it remained in the stomach for a long time without being cleared, the patient would lose consciousness, accompanied by nausea, diarrhea, headache, and damage to vital organs. - Long-term exposure to copper sulfuric acid may cause a large accumulation of copper ions in the body, leading to insomnia, dizziness and other abnormal symptoms of the nervous system. Serious copper poisoning may cause breathing difficulties and even fainting and other shock symptoms. It may induce heart disease in the elderly and mental disorders in children. - After entering the human body, it was difficult for copper sulfuric acid to be expelled from the body. It mainly adhered to organs such as the liver, gallbladder, and kidneys, which could lead to serious consequences such as organ failure, uremia, and blood diseases. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction between methylamine (CH3NH2) and sulfuric acid (HNO3) will have the following phenomena: ** 1. Phenomenon in the reaction process ** 1. ** Generates heat ** - This was an acid and base neutralizing reaction. The methylamine was an acidic substance, while the sulfuric acid was an acidic substance. When they mix, the reaction will release heat, just like you can feel the temperature change when you mix hot water and cold water, but the heat change in this reaction is more obvious. 2. ** Generates smoke-like substance (possible)** - The reaction might produce some aminium salt, such as methylethylane (CH3NH3NO3). During the reaction process, if the reaction was intense or volatile substances were produced, one might see a phenomenon similar to smoke. It was like the feeling of steam coming out when boiling water, but it was formed by the substances produced by the reaction. 3. ** The color of the solution changes (if there are impurities or special circumstances)** - If there were impurities in methylamine or sulfuric acid, or in a specific environment, the color of the solution after the reaction might change. However, if it was the reaction of pure methylamine and sulfuric acid, the reaction product, methylaminium nitrates, was generally colorless. The color of the solution usually did not change too much, and it was as clear and transparent as water. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Ferric acid (FeCl2) solid does not react with sulfuric acid (HQ). In chemistry, there was no chemical reaction when iron chloride-sulfuric acid was mixed, because they existed in the form of ions in the solution (Fe3, Cl3, H3, Cl3). These ions did not produce new substances, which did not meet the conditions for chemical reactions (forming new substances such as precipitations, gases, or water). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
