Non-metallic elements react with water to form weak acid
This statement was wrong. For example, the reaction of Cl2 with water to produce Cl2 and hypochloric acid, the reaction equation is Cl2 + H2O = Cl2 + HClO, and Cl2 is a strong acid. In addition, the reaction of some elemental haloids with water to form acid was a reduction reaction, and only non-metallic elemental substances that met both oxidisation and reduction could undergo a reduction reaction with water to form acid. Not all non-metallic elemental substances reacted with water to form weak acid. Read more exciting novels for free
Which react with water and acid first?
When substances such as Na and Na react with water and acid, they react with acid first. From the reaction phenomenon, for example, the reaction between Na and acid solution was much more intense than the reaction with water. It could be judged that when Na reacted with acid solution, it would react with acid first, and if the acid was insufficient, it would react with water. Theoretically, when Na was put into water, it would react with acid first (assuming that the product formed by the reaction with water first would react with acid immediately), but in reality, it would react with both water and acid. However, the reaction between sulfuric acid and sulfuric acid was to react with water first, then react with acid after producing sulfuric acid. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
lead acid and water
The correct way to add water to a lead-acid battery is to use a plastic funnel to slowly pour distilled water or Deionized water into the battery to ensure that the water does not splash on the battery casing or other components, and to avoid pouring water into the battery's charging port or other non-water-adding ports. After adding water, close the battery cover in time and screw it tightly to prevent the water from evaporating. Before adding water, first check whether the battery level is lower than the indicator line. Only when the liquid level is lower than the indicator line do you need to add water. Use distilled water or Deionized water to add water. Do not use tap water or other water containing impurities to avoid affecting the battery's working effect. When adding water, pour water slowly to avoid splashing on the battery casing or other components to avoid short circuit or other failures. Adding too much water would cause the battery to overflow, reduce performance, accumulate water in the box, and corrode. In serious cases, it might cause the battery to short-circuit. Therefore, it is necessary to add a small amount of water many times. It is strictly forbidden to add too much water to exceed the maximum liquid level.
Why can't carbolic acid react with hypobaric acid?
Carbonic acid can react with hypobaric acid. According to the comparison of the two, the first-order ionisation constant of H CO was larger than that of HClO, and the second-order ionisation constant was smaller than that of HClO (K1(H CO)> K (HClO)> K(HCO). The reaction equation between the two was Na CO +HClO = NaHCO +NaClO, but the reaction could not release carbon dioxide gas. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How does a fictional weak base Zah2 react with water to yield?
The reaction of Zah2 with water could result in various products depending on factors like the chemical bonds within Zah2. Maybe it leads to the formation of new compounds or ions, but we need more information to determine exactly what happens.
Why can't the reaction of the sulfuric acid react with the sulfuric acid?
The reaction equation is: NaH + CH30H → CH3ONa +H2O. This reaction was a strongly irreversible reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is mineral water divided into acid and base?
The mineral water was divided into acid and base. There were two types of mineral water: acidic and basic. Natural sources of water all contain natural sources of basic mineral elements such as potassium, calcium, and calcium. They are naturally weakly basic, and this natural weakly basic water is suitable for long-term drinking. The novel, Drunken Golden Cup, is equally exciting. Everyone is welcome to click and read it!
Copper and silver react first with sulfuric acid
From the metal activity sequence table, it could be seen that copper was more active than silver. Nitric acid was a strong oxidistic acid, and it would react with metals with strong reducing properties first, which meant that it would react with copper first. Moreover, if silver reacted first to form silver nitrates, copper could reduce silver nitrates to silver and form copper nitrates. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

A class of substances that can react with acid to produce gas
There were several types of substances that could react with acid to produce gas: 1. Metal activity ranked before H. This type of metal would undergo a displacement reaction with acid to release gases, such as Na, MG, AI, and Fe. 2. For example, CaCOcan react with acid to form CO2, and NaHCOcan also react with acid to form carbon dioxide. 3. Sulfites and bithites react with strong acid to form sulfur dioxide gas. For example, when BaSO2 react with acid, it will form SO2. 4. Metal Sulfides and Sulfur Hydrides react with strong acid to form hydrogen Sulfates, such as Sulfur Sulfides, which react with acid to form H ^S (generally believed to require concentrated sulfuric acid). 5. The corresponding salt of a weak acid would react with a strong acid to form an acidic gas, and react with a strong base to form an aromatic gas. For example, the reaction of an aromatic acid with an acid would form carbon dioxide, and the reaction of an aromatic acid with a base would form aromatic gas. 6. Special substances such as Mn <2>, which can produce Cl2 by oxidisation of HQ (requires concentrated HQ); F <2> can also produce Cl2 by oxidisation of HQ. 7. When a bleacher is mixed with an acid (such as vinegar), it will produce Cl2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
