Propionic acid reacted with a sufficient amount of metallic Na
Propionic acid (CH CH2 COOx) reacted with a sufficient amount of metallic Na. Two moles of proprionic acid reacted with two moles of metallic Na to form two moles of proprionic acid (CH CH2 COONa) and one mole of hydrogen gas (H2). The reaction equation was: 2CH CH2 COOx + 2Na → 2CH CH2 COONa + H2 ^. This was because the hydrogen in the acidic group (-COCH) in the sulfuric acid was active and could be replaced by metallic Na. The ratio of the amount of substances in the above reaction was obtained according to the stoichiometric-relationship. Read more exciting novels for free
The equation of the reaction between a small amount of bisulfuric acid and a sufficient amount of lithium hydrogen.
The chemical equation of the reaction between a small amount of bisulfuric acid and a sufficient amount of lithium hydrogen is: $NaHSO4 +Ba(Ox) 2 =H_{2}O+ NaOx + BaSO4 < The principle of the reaction was that the hydrogen ions and the sulfuric acid ions in the bisulfuric acid reacted with the hydrogen ions and the sulfuric acid ions in the lithium hydrogen. Due to the small amount of the bisulfuric acid, the hydrogen ions and the sulfuric acid ions contained in it completely reacted in a ratio of 1:1 to produce water, the precipitations of the lithium hydrogen and the lithium hydrogen. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation of iron with a sufficient amount or a small amount of Cl2
The reaction equation between iron and Cl2 was: 2Fe +3Cl2 = 2FeCl2 (ignition). The reaction was independent of the amount of Cl2. The reaction equation was the same regardless of whether there was a sufficient amount or a small amount of Cl2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Add sufficient amount of soda to react with aluminum sulphate.
The reaction was divided into two steps when a sufficient amount of NaOH_2 O_3 was added to Al2SO4. The first reaction (Al2 (SO4) 3 + 6NaOx = 2Al2 (SO4) 3 + 3Na2SO4), due to the sufficient amount of NaOx, the formation of aluminum trioxid The reaction equation is [Al2 (SO4) 3 + 8NaOx = 2NaAlO2 + 3Na2SO4 + 4H2O]. The reaction equation is the same as the reaction equation between the two metals. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The same amount of Na and Al.
The reaction of the same amount of substances of aluminum and aluminum with water was carried out in two steps. First, the reaction of Na with water: 2Na +2H ^O == 2NaOx + H ^; The resulting soda reacted with aluminum: 2NaOx +2AI + 2 ^H ^O == 2NaAlO ^+3H ^. The total reaction equation is: 2Na +2AI +4H ^O == 2NaAlO ^+4H ^. In terms of reaction phenomena, when the reaction between the two was carried out, it would float on the surface of the water, melt into a silver-white ball, and swim around on the surface of the water, accompanied by a sizzling sound. If there was a drop of phenothalin in the water, it would turn red. When the reaction between aluminum and the solution of the two was carried out, the aluminum would gradually dissolve. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction of the bisulfuric acid and a small amount of dilute sulfuric acid
The reaction of hydrogen bionate and a small amount of dilute sulfuric acid will produce sulfuric acid and nitrogen dioxide. The reaction equation is: 2NaHSO3 + 2HNO3 → 2H2SO4 + 2NO + H2O. This was an oxido-reduction reaction. Sulfite ions in the bisulfuric acid had a reducing property. They were oxided by the nitrates in the dilute sulfuric acid to become sulfuric acid ions, and at the same time, the sulfuric acid was reduced to nitrogen dioxide. The essence of the reaction was: 3SO32- +2H + +2NO3- = 2NO ^+ H2O +3SO42-. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction between the amount of hydrogen sulfuric acid and the amount of substances such as soda
When the amount of substances such as the reaction of the hydrogen sulfuric acid (<anno data-annotation-id ="cd000004 - 4c04 - 4c00-a110-a11111111004"> NHSO4 </anno>) and the like react, the reaction equation is: <anno data-annotation-id ="3cd000 - 4c00 - 4c00-a11111100000"> NHSO4 + NH3 </anno>="aHSO4 + NH2 + O </anno>. During the reaction process, the hydrogen ion in the hydrogen sulfuric acid first reacted with the lithium hydrogen. Since the amount of the two substances was equal, the lithium ion did not participate in the reaction, forming the hydrogen sulfuric acid and the lithium hydrogen. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction of Na with diluted sulfuric acid and sulfuric acid
The reaction between the dilute sulfuric acid and the sulfuric acid was very intense. The chemical properties of Na were very active. When it was placed in diluted sulfuric acid, Na would first react with water to form Na_2 and H_2. The chemical equation was 2Na +2H_2 O = 2Na_2 Sulfur and H_2. The resulting Na_2 would then react with diluted sulfuric acid. The chemical equation was 2Na_2 Sulfur and H_2 Sulfur = Na_2 Sulfur and 2H_2 O. When the solution was added to the acid, it would react with water to form hydrogen and hydrogen. At the same time, the hydrogen would react with the acid immediately. The chemical equation was 2Na +2HQ = 2NaCl2 + H ^. In short, the reaction between the two acids and the sulfur would produce hydrogen. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
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. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Image of the reaction of the same amount of metal and acid
1. ** Reaction of the same amount of metal with sufficient acid (horizontal coordinate is reaction time)** - Reaction rate relationship: When the same mass of Mn, and Mn react with a sufficient amount of the same acid of the same mass and concentration, the reaction rate relationship is: Mn> Mn. This was because under the conditions of a certain temperature, metal particle size, and solute mass fraction of the diluted acid solution, the stronger the mobility of the metal, the faster the reaction to produce hydrogen. - The mass relationship of the final hydrogen produced: The mass relationship of the final hydrogen produced is: 2. ** Reaction of the same amount of metal with sufficient acid (the horizontal coordinate is the mass of acid)** - When the same mass of Mn, and Mn reacted with a sufficient amount of sulfuric acid of the same mass and concentration, and the metals completely reacted, the mass relationship of the final hydrogen produced was: Mn> Mn. 3. ** Reaction of an equal amount of acid with a sufficient amount of metal (horizontal coordinate is reaction time)** - Reaction rate relationship: When the same acid with the same mass and concentration and sufficient amount of Mn, and Mn react sufficiently, the reaction rate relationship of hydrogen is: Mn> Mn. - The mass relationship of the final hydrogen produced: The mass relationship of the final hydrogen produced is: 4. ** Reaction of an equal amount of acid with a sufficient amount of metal (the horizontal coordinate is the mass of the metal)** - The mass relationship of the final hydrogen produced: When the same acid with the same mass and concentration and a sufficient amount of Mn, and Mn react sufficiently, the mass relationship of the final hydrogen produced is: Mn = Mn. When analyzing the image problem of the reaction between metal and acid, it was necessary to pay attention to the specific meaning of the ordinate and ordinate in the image. Generally, the ordinate was the amount of hydrogen produced, and the ordinate was usually time/s or the mass of acid consumed/g or the mass of metal consumed/g. At the same time, it was necessary to judge the amount of metal and acid. The amount of hydrogen produced in the reaction was determined by the amount of acid in the reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
