What is the total number of electrons transferred from the reaction of nitrogen dioxide and water?
According to the equation of the reaction between nitrogen dioxide and water, two of the valences, N, become the valences of +5, and one of the valences becomes the valences of +2. That is, every three valences of NO_{2} will transfer two electrons. Read more exciting novels for free
Which reaction is stronger, nitrogen dioxide or water?
" Which reaction is more powerful, nitrogen dioxide or water?" The expression was not very accurate. The reaction between nitrogen dioxide and water was 3NO <2>+ H <2> O = 2HNO <2>+ NO. This reaction was a manifestation of the chemical properties of nitrogen dioxide, and there was no comparison between the two. The nitrogen dioxide was a brownish-red gas with a pungent smell. During the reaction process, it interacted with water to form nitrogen dioxide and nitrogen dioxide. This was a specific chemical reaction process, not a competitive or " fierce " relationship. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Distinguish the reaction equations of nitrogen and carbon dioxide with water
The chemical properties of nitrogen were stable, and it usually did not react with carbon dioxide and water. The chemical equation for the reaction between carbon dioxide and water is: CO2 Ü + H Ü O = H Ü CO2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the essence of the reaction between nitrogen dioxide and water
The essence of the reaction between nitrogen dioxide and water was that the nitrogen element would undergo its own oxido-reduction reaction. In the reaction, 3 <2> NO <2>+ H <2> O = NO +2HNO <2>, 3 moles of +4-valency nitrogen element, 2 moles of which are oxided into +5-valency nitrogen element, losing 2 moles of electrons, forming 2 moles of sulfuric acid;1 mole is reduced to +2-valency nitrogen element, obtaining 2 moles of electrons, forming 1 mole of nitrogen dioxide. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

How to differentiate the reaction of methane, nitrogen, carbon dioxide and bromine water?
There was no reaction between methane and bromic water, and there was no reaction between hydrogen and bromic water (hydrogen was basic and could react with acidic substances in bromic water). There was no reaction between carbon dioxide and bromic water. The following methods could be used to identify methane, nitrogen, and carbon dioxide: 1. ** Lime water clarification method **: The gas is separately introduced into the clarified lime water. What can make the clarified lime water turbid is carbon dioxide. This phenomenon does not occur with the use of methane and nitrogen. 2. ** Moist red litmus test paper method **: The wet red litmus test paper was placed close to the gas. The test paper turned blue because of the presence of nitrogen, but not because of the presence of carbon dioxide and methane. 3. ** combustion method (for the identification of methane)**: ignite the gas. What can be burned is methane, but carbon dioxide and hydrogen cannot be burned. In summary, carbon dioxide could be identified by clarification of lime water, then the wet red litmus test paper could be used to identify nitrogen, and finally the combustion method could be used to identify methane. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Phenomenon analysis of the reaction equation between sulfur dioxide and nitrogen dioxide
The reaction equation between nitrogen dioxide and sulfur dioxide is: <anno data-annotation-id ="c3d-a100 - 4c00 - 4c50-a150 - 9c3333c3333"></anno></anno> Phenomenon analysis: From the reaction equation, it can be seen that nitrogen dioxide is a brownish-red gas. After the reaction, it will produce nitrogen dioxide, which is a colorless gas. Therefore, the color of the brownish-red gas will gradually fade until it disappears. At the same time, the sulfur dioxide generated was a colorless gas. Under certain conditions (such as water), there would be further reactions. For example, sulfur dioxide would react with water to form sulfuric acid, which might cause acid mist and other phenomena. However, from the perspective of the reaction between the two, it was mainly a change in the color of the gas. In addition, this reaction was a complex gaseous reaction that occurred at a high temperature. It mostly occurred in a specific environment with a heated climate. The existence of a large number of reaction products could cause air pollution and affect atmospheric visibility. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to identify the reaction between carbon dioxide and nitrogen

What's the reaction of lightning to the equation of nitrogen dioxide?
When lightning struck, nitrogen reacted with oxygen to form nitrogen dioxide, which further reacted with oxygen to form nitrogen dioxide. The reaction equation is: N <2>+O <2> →2NO (discharge condition), 2NO + O <2> →2NO <2>. This series of reactions belonged to the oxido-reduction reaction. During the reaction, the valency of the nitrogen and oxygen elements changed. The valency of the nitrogen element in the nitrogen gas increased from 0 to +2 in the nitrogen dioxide, and then to +4 in the nitrogen dioxide. The valency of the oxygen element in the oxygen gas decreased from 0 to-2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
