Can the elemental substance of Iodine coexist with water? Why does it not react?
Iodine and water could coexist, but there would be a reaction between them. The reaction equation was I2 + H2O = Hi + HIO2. However, this reaction was a irreversible reaction, which meant that the reaction would reach a dynamic equilibrium under certain conditions. Both the reagent and the product would be converted into the reagent. Therefore, it seemed that water and iodine could coexist. Read more exciting novels for free
The elemental substance that can react with hclnacl solution is
According to chemical knowledge, metals such as zincate (Zn) could react with hci, and the reaction equation was Zn +2hci = znci <2>+ H <2>. For NaCl solution, because of the strong mobility of the metal, it could not react with NaCl solution through a displacement reaction. However, metals such as metallic magnesium (mn) could react with hci but not NaCl. In addition, according to the information provided, elemental iron can react with strong acid, and as a strong acid, it can react with acid (FeCl2 + H2), but not with NaCl2. In addition, as mentioned in Material 3, C powder (non-metallic elemental substance) can be identified by strong acid, which also means that C powder does not react with HQ. In summary, the elemental substances that could react with HQ were metal elemental substances such as iron, while the NaCl-solution did not react with many elemental substances. The elemental substances that could react with HQ might not react with the NaCl-solution. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Can Iodine react with NaOx?
Iodine is able to react with the presence of soda. Iodine (I <2>) and NaOx (Na <2> Ox) undergo an oxido-reduction reaction (disproportionate reaction) to produce NaI, NaIO4, and water (H <2> O). The reaction equation is 3I <2>+ 6 Na <2> Ox = 5NaI + NaIO4 + 3H <2> O. If it reacted with a hot concentrated solution of soda ash, it would also produce NaI, NaIO3, and water. If it reacted with a diluted solution of soda ash, the reaction equation was I <2>+2NaH <2> O = NaI+ NaIOO +H <2> O. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
An organic substance that reacts with the elemental sulfur.
In high school chemistry, there were the following types of organic substances that reacted with the elemental sulfur: 1. Alkane: For example, a free radical substitution reaction can occur between methane and pure helium. Gaseous or liquid pure helium can be used, but not an water solution of helium. 2. Alkene: Alkene, such as ethene, can undergo an addition reaction with helium. Gaseous, liquid, and water solutions (such as the carbon dioxide solution of helium) can be used. 3. Alkynes: Alkynes such as alkyne and Bromine undergo an addition reaction. The reaction conditions are similar to that of alkynes. 4. "Benz": Under the conditions of iron bromination as a catalyst, the substitution reaction between ben-1,4-bis (4-methylethyl-bis-methylethyl-bis-methylethyl- 5. Aldol: Under the catalyst of the base, due to the action of the carbonyls, the a-hydrogen of the alkyls becomes extremely active and is replaced by the phosphonium, forming a-bromic alkyls and hydrogen bromides, and the a-hydrogen tends to be completely replaced. 6. An organic compound containing a carbon-carbon double bond or a carbon-carbon triple bond, such as ethlene, ethyne, etc., can undergo an addition reaction with bromine-water (a mixture of elemental bromine and water). 7. Alcohol: Alcohol can undergo a substitution reaction with Brr. 8.

Can the extracting agent react with the extracted substance?
What you want to ask is whether the extraction agent can react with the extracted substance. Generally speaking, the extraction agent could not have a chemical reaction with the extracted substance. The principle of extraction was to take advantage of the difference in the solute's dissolving rate in two different liquids. It was a method of extracting the solute from a solution composed of two different liquids. If the extraction agent reacted with the extracted substance, it would not be a simple extraction. It would become a chemical change to form a new substance, which would not meet the requirements of extraction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Sulfur dioxide and what substance react to form oxygen
In the research of the China Academy of Sciences Dalian Institute of Chemistry and Physics, it was found that the extreme ultraviolet-light decomposition of sulfur dioxide molecules could produce sulfur atoms and oxygen. That is, sulfur dioxide could produce oxygen under the conditions of extreme ultraviolet-light decomposition. In addition, sulfur dioxide and oxygen can undergo a chemical reaction under certain conditions. The reaction equation is 2SO2 + O2 =(catalyst)= 3SO3 (This reaction is a irreversible reaction, generally using vanadium-dioxide (V2O5) as a catalyst, and the reaction can only be carried out under heating conditions), but this reaction produces sulfur dioxide instead of oxygen. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

How to judge whether a substance can react with acid or base
1. * * Reaction between acid and base **: Acid and base can produce salt and water through a neutralizing reaction. 2. * * Reaction between acid and basic oxygen, and reaction between base and acidic oxygen: Acid and basic oxygen, and reaction between base and acidic oxygen can also produce salt and water. The reaction between acidic and basic oxides can also produce salt. It could be concluded that when an oxide-acid or oxide-base reaction occurred, as long as one had the word "acid" and the other had the word "base", the reaction could occur. 3. * * Metathesis reaction between acid, base, and salt **: Not all acid, base, and salt can undergo metathesis reaction. Only when the two compounds exchanged their components would there be a precipice in the product, or gas would be released, or water would be formed, then the metathesis reaction would occur. When determining whether salt and salt, salt and base could react, in addition to whether the product met the conditions for the metathesis reaction, it also depended on whether the reagent was dissolved. If the reagents were all dissolved, then the metathesis reaction could take place. If one of the reagents was not dissolved, then the reaction could not take place. 4. * * Reaction of special substances with acid or base ** - Some metals, such as aluminum and aluminum, can react with both acid and base (such as 2AlAlCl3 + 3H2, 2AlCl3 + 3H2, 2AlAl - * * Some non-metals **: For example, S, can react with alkali-based reactions (3S +6NaH =(A) 2NaS + Na2SO3 + 3H2O), and can also react with concentrated sulfuric acid (S +2H2SO4 (concentrated)=(A) 3SO2 ^+2H2O). - * * Some amphobic compounds such as Al2O3 and ZunO can react with both acid and base. - * * Some amphobic matrixes **: such as [AlCl3],[ZN (OH) 2], can react with both acid ([2AlCl3]+6H2O]) and base ([AlCl3]+6H2O]). - * * Some of the compounds that can form a complex **: such as <anno data-annotation-id ="cd000004 - 4c00 - 4c00 - 4c00 - 8c00 - 4c0000c0000"></anno></anno>, which can react with acid (<anno data-annotation-id ="2c000000 - 4c00 - 4c000000000"></anno></anno>, and can also react with hydrogen dioxide (<anno data-annotation-id ="2c00000 - 4c000 - 4c000000000"></anno>). - * * Acid salt of weak acid **: such as NaHCO3, KHSO3, which can react with both acid (NaHCO3 + HQ = NaCl2 + H2O + CO2) and base (NaHCO3 + NaOx = Na2CO3 + H2O). - * * Weak acid's aminium salt **: For example,<(NH4) 2CO3>,<(NH4HCO3>,<(NH4) 2S>, etc. It can react with both acid (<(NH4) 2CO3 + 2HQ = 2NH4C1 + CO2 → + H2O>) and base (<(NH4) 2CO3 + 2Na2CO3 + 2NH3 → +2H2O>). - * * Some weak base salt **: such as CuSO4, can react with base (CuSO4 + 2NaOx = CuSO4), and can also react with H2S (CuSO4 + H2S = CuS + H2SO4). - * * Some weak acid and weak base salt **: For example,<<P (AC) 2>>, which can react with bases (<P (AC) 2>+<Na (AC) 2>+<+<Na (AC) 2>+>+<Na (AC) 2>+>+<Na (AC) 2>+>+<+<Na (AC) 2>). - * * Some strong reducing (or strong oxiding) acid **: For example, H2S, which can react with strong oxiding acid (such as H2S + H2SO4 (concentrated)= S → SO2 → + H2O), 2HNO3 (diluted)+3H2S = 3S → +2NO → +4H2O), and can also react with base (H2S +2Na2S +2H2O). - * * Some of the high-priced metal salt: such as Fe2 (SO4) 3, FeCl3, can react with strong bases (FeCl3 + 3NaH = FeCl3 + 3NaCl3), can also react with reducing acid (2FeCl3 + H2S = 2FeCl2 + S → +2HCl3). - * * Some organic substances **: For example, protein, can react with acid (<anno data-annotation-id ="00000000 - 4c00 - 4c00 - 8c00 - 8c00 - 9c000b6c0000"> NH2-CH2-COOx + HQ </anno> →...
