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.

Reaction of carbon dioxide and methane
The chemical equation for the reaction between methane and carbon dioxide was CH + CO Ü = 2CO +2H Ü; there was also a thermal chemical equation for the reaction between methane and carbon dioxide, CH + H Ü O = CO +3H Ü. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to identify the reaction conditions of methane, nitrogen, carbon dioxide and oxygen
The reaction between methane and sufficient oxygen was ignited to form water and carbon dioxide; carbon dioxide and nitrogen reacted under high temperature and high pressure to form carbolic acid and water; the reaction between oxygen and nitrogen was not mentioned in the reference materials; carbon dioxide and water reacted under the effect of titanium (normal temperature and pressure) to form substances such as methane, methanoi, and formated acid, not with oxygen. Therefore, based on the available information, it could be confirmed that the reaction between methane and oxygen was the ignition condition, and the reaction between carbon dioxide and hydrogen was under high temperature and high pressure. The reaction conditions for oxygen and hydrogen could not be accurately given. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The equation of carbon dioxide formed by the reaction of carbon dioxide and water
The reaction between the soda ash and water would not directly produce carbon dioxide. The reaction between the water and the carbon dioxide was a reaction of water and carbon dioxide. The first stage of the reaction was: Na2CO3 (carbon dioxide)+H2O (water)= NaHCO3 (carbon dioxide)+ NaOx; the second stage of the reaction was: NaHCO3 (carbon dioxide)+H2O (water)= H2CO3 (carbon dioxide)+ NaOx. The reaction was irreversible. The reaction between the two would produce carbon dioxide, and the chemical equation was: Na2CO3 + 2HQ == 2NaCl2 + H2O + CO2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
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>
Reaction of carbon dioxide with acid, base and water
1. **二氧化碳与碱的反应** - 二氧化碳能与可溶性碱反应，产物一般是碳酸盐。例如二氧化碳与氢氧化钠反应：当二氧化碳少量时，\(2NaOH+CO_{2}=Na_{2}CO_{3}+H_{2}O\);二氧化碳与氢氧化钙反应\(Ca(OH)_{2}+CO_{2}=CaCO_{3}+H_{2}O\)。不过并不是所有的碱都能和二氧化碳反应，只有可溶性碱能与二氧化碳发生反应。 2. **二氧化碳与酸的反应** - 二氧化碳不与酸反应，从酸碱性角度看，酸和酸不反应，并且二氧化碳既没有强氧化性也没有强还原性，所以和氧化/还原性酸也不反应。 3. **二氧化碳与水的反应** - 二氧化碳遇到水时发生化学变化，产生碳酸，反应方程式为\(CO_{2}+H_{2}O = H_{2}CO_{3}\)，但碳酸不稳定，受热易分解，\(H_{2}CO_{3}\triangleq CO_{2}\uparrow+H_{2}O\)。 <a href="/?from=ask_words" style="color:red" target="_blank">点击前往免费阅读更多精彩小说</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>

Acid base reaction carbon dioxide
Acid and base reactions can produce carbon dioxide. For example, the reaction of soda ash (Na_{2}CO_{3}) with an acid (such as sulfuric acid,<anno data-annotation-id ="00000000 - 4110 - 4410-a110-a1100111000"> ClCl3 </anno>) will produce carbon dioxide. The reaction equation is <anno data-annotation-id ="2c3cd00 - 4c50 - 4c50 - 4c50 - 9c51100000000"> Na_{2}CO_{3}+2Cl3 + 2Cl3 = 2NaCl4 + H_{2}O+ CO2}</anno></anno>. In the laboratory, diluted sulfuric acid reacted with marble (the main component of calcium dioxide) to produce carbon dioxide. The chemical equation was [CaCO3]+2HQ = CaCl2 + H2O + CO2]. The reaction between edible alkali-based and acid could produce carbon dioxide. When the dough fermented too much and had a sour taste, edible alkali-based could neutralize the sour taste. At the same time, the reaction between alkali-based and acid produced carbon dioxide to make the dough more fluffy and puffed. Baking soda (acidic) could also produce carbon dioxide when it reacted with acidic substances. For example, when white vinegar (acidic) and baking soda were mixed at home, they would react to produce carbon dioxide, which could be used for simple scientific experiments. The carbon dioxide produced by the reaction could make the balloon bulge, and the gas could extinguish the flame. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is there a reaction between carbon dioxide and water to form carbolic acid? Why?
The reaction between carbon dioxide and water will produce carbolic acid, and the reaction equation is: CO2 + H2 O = H2 CO2. In terms of the nature of the reaction, the carbon atoms in the carbon dioxide molecules and the oxygen atoms in the water molecules formed new chemical bonds, which combined to form carbon dioxide molecules. In this reaction process, because carbon dioxide was an acidic oxide-like substance, its chemical properties allowed it to react with water to form acid. This reaction could also be verified through experimental phenomena. For example, when carbon dioxide was added to water containing purple litmus test solution, the solution would turn red. This was because the generated carbon dioxide was acidic and could cause the litmus test solution to change color. Carbonic acid was unstable and would decompose into carbon dioxide and water under heating conditions. This process was the reverse reaction of the above reaction, and the two constituted a irreversible reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Why does the reaction of carbon dioxide and magnesium produce carbon?
The carbon element in carbon dioxide has a +4 valency, which is oxidisable. When the reaction between carbon dioxide and carbon dioxide occurs, the carbon element in the carbon dioxide is reduced from +4 to 0. The reaction equation is 2MG + CO2 = ignition = 2Magnesia + C. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
