The following is related to the experiment of the reaction between magnesium-aluminum and oxygen: ** 1. Reaction between Magnesium and oxygen ** 1. ** Reaction Phenomenon ** - When it burned in the air, it would release heat and emit a dazzling white light, forming a white solid. - The reaction was more intense in oxygen than in air. 2. ** chemical equation **:<2MG + O_{2}><stacking>{=<<=<<=>>>=<>>2MgO\) 3. ** Points to note in the experiment ** - Due to the intense combustion of the titanium, safety must be paid attention to during the experiment and a certain safe distance must be maintained from the titanium. - When burning, it will produce a strong light, which may cause damage to the eyes, so don't look directly at the burning magnetite. ** 2. Reaction between aluminum and oxygen ** 1. ** Reaction Phenomenon ** - When aluminum reacted with oxygen in the air, a layer of dense aluminum dioxide film would be formed on the surface of the aluminum. This film would prevent the aluminum from being further oxided, so the reaction between aluminum and oxygen in the air was not so intense. The surface of the aluminum gradually lost its metallic luster. - If the aluminum foil was heated in oxygen, the aluminum foil would melt, but it would not drip. This was because the melting point of the aluminum dioxide film was very high, and it would hold the molten aluminum and emit a dazzling light during the reaction. 2. ** chemical equation **:<4AI +3O_{2} = 2AI_{2}O_{3}> 3. ** Points to note in the experiment ** - When conducting the experiment of heating the aluminum foil in oxygen, the purity and sufficient supply of oxygen must be ensured. - When heating the aluminum foil, use a suitable heating tool, such as an alcohol lamp, and heat it evenly. ** 3. Experimental design (Comparing the reactions of oxygen with aluminum and aluminum)** 1. ** Experiment Purpose ** - Comparing the intensity of the reaction between aluminum and oxygen, the reaction products, and so on. 2. ** Experiment Steps ** - He took a suitable amount of aluminum foil and a suitable amount of aluminum strip, and polished them to make them bright (to remove the thin film of oxygen on the surface). - Heat the aluminum foil and the aluminum strip separately over the flame of an alcohol lamp (or ignite them in a gas collector filled with oxygen). - Observe and record the intensity of the reaction between the two (such as the reaction of the aluminum strip is more intense, emitting a dazzling white light; the surface of the aluminum foil gradually changes when heated, and it will also emit light when ignited in oxygen, etc.), and the phenomenon during the reaction (such as the combustion of the aluminum strip to form a white solid, the formation of a white aluminum dioxide film on the surface of the aluminum foil, etc.). - After the reaction, the reaction product was analyzed (it could be judged by physical properties such as color and state, or it could be further analyzed by chemical methods). 3. ** Experiment result analysis ** - Based on the intensity of the reaction, it could be judged that the reaction between oxygen and titanium was easier than that of aluminum. - Through the analysis of the reaction products, it could be determined that the reaction between the oxygen and the aluminum formed the aluminum dioxide. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
When there was a small amount of oh-ions, the chemical equation of the reaction between aluminum ions and oh ions was: Al3 ++3OH - =Al(OH)3; when there was an excess of oh-ions, the chemical equation of the reaction between aluminum ions and oh ions was: Al3 ++4OH - = AlO2-+2H2O. When a small amount of oh-ions gradually becomes excessive, the chemical equation of the reaction between aluminum ions and oh ions is: AI (OH)3+OH - = AlO2-+2H2O. The ion equation for the reaction of aluminum with water is: 20H- +2Al+2H2O→ 2AlO2-+3H2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction between aluminum and iron dioxide (thermit reaction) experiment was as follows: ** 1. Experimental Materials ** Materials such as aluminum powder, iron dioxide, aluminum strip, alcohol lamp, paper funnel, iron frame, etc. were required. ** 2. Experimental Steps ** 1. A small amount of dried iron dioxide and an appropriate amount of aluminum powder were evenly mixed and placed in a paper funnel. A small amount of potassium peranate solid was added to the mixture, and a piece of magnetite strip that had been polished with sandpaper was inserted in the middle (the polishing was to remove the oxide-film on the surface of the magnetite strip for ignition). 2. He ignited the magnum strip. ** 3. Experimental Phenomenon ** 1. It immediately reacted violently. 2. It gave off a dazzling light and produced a large amount of smoke. 3. The paper funnel was burnt. 4. Some red-hot liquid beads fell onto the fine sand in the evaporating dish. After the liquid beads cooled down, they turned into a black solid. ** 4. The chemical reaction equation ** Fe2 O2 + 2Al2 = high temperature = Al2 O2 + 2Fe2. This reaction was a replacement reaction and a reduction reaction. There was no catalyst involved in the reaction. ** 5. Points to note ** 1. The paper funnel inside the glass funnel should be thicker and moistened with water to prevent damage to the funnel. 2. The evaporating dish should be lined with a suitable amount of fine sand to prevent the evaporating dish from exploding and to prevent the molten liquid from splashing out and hurting people. 3. The experimental equipment should not be too close to people to prevent them from getting injured. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Add sufficient amount of hydrogen into the solution of Al3 +, and the reaction equation is: Al3 + +3NH3·H2O = AI (OR)3 → +3NH4 +; The reaction of hypochlorites and tertiary aluminum ions with water can also produce aluminum trioxides, and the reaction equation is: Al3 + + 3ClO- +3H2O = AI (OR)3 → +3HClO; The reaction of aluminum with water can also produce aluminum trioxides, and the reaction equation is: 2AI +6H2O → 2AI (OR)3 → +3H2 →. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

When oxygen meets sulfur, it will react and release a lot of heat. For example, when the reaction between hydrogen sulfureted and oxygen was small, it would produce sulfur and water. The chemical equation was [O2 + 2H2S = 2S +2H2O]. When the oxygen was excessive, it would produce sulfur dioxide and water. The chemical equation was [3O2 + 2H2S = 2SO2 + 2H2O]. Sulfides in the sulfurous waste water of oil refineries (usually in the form of Na salt or NH4) react with oxygen in the air as follows: <2HS^-+ O2 → SO4 ^{2 -}+ H2O>,<2S +2O2 + H2O → SO4 ^{2 -}+2Ox ^->,<SO3 ^{2 -}+ O2 + Ox ^-→ 2SO4 ^{2 -}+ H2O>. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Aluminiothermic reaction was a kind of oxide-reduction reaction between aluminum and metal or non-metal compounds at high temperatures. Aluminiothermic reaction was an exhaling reaction, and its heat release was very large, usually enough to heat the product above the melting point, and the reaction could generally occur locally and be self-sustaining. This characteristic also reflected the energy-saving characteristics of the reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Dieselfuel is a complex mixture, its main component is a carbon dioxide (CnH2n +2, etc.). The chemical equation of its combustion reaction is: CnH2n +2+(3n +1)/2O2 → nCO2 +(n + 1)H2O. However, in actual diesel combustion, due to the air composition (including N2, O2, etc.) and different combustion conditions, the combustion products include carbon dioxide and water, carbon dioxide (produced when there is no oxygen), carbon dioxide (produced when incomplete combustion), nitrogen dioxide (produced when high temperature and oxygen are rich), sulfur dioxide (produced when diesel contains sulfur), etc. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
