How to write the junior high school reaction into an ion equation
Rewriting the junior high reaction into an ion equation generally followed the following steps: ###1. Write the chemical equation First of all, he had to write down the chemical equation of the reaction. This was the foundation. If the chemical equation was written wrong, the subsequent steps would be wrong. ###2. Dismantle the chemical formula 1. ** Dismountable material ** - Strong acid, strong base, and dissolved salt could be written in the form of ions. - Strong acid generally included sulfuric acid, hydrogen acid, hydrogen iodate, peroric acid, etc. in water solutions. - Strong bases such as lithium, lithium, and lithium were in the water solution or molten state (the middle school stage focused on the water solution). - Most of the salt could be disassembled in an water solution or molten state (the emphasis in junior high school was on water solution), such as the common salt, such as the common salt such as salt and salt. 2. ** Non-dismantled substance ** - A simple substance couldn't be dismantled because a simple substance wasn't made of ions. - Solids (such as poorly dissolved solid such as calcium dioxide) could not be dismantled. They mainly existed in solid form in the solution, not in the form of ions. - Oxides could not be dismantled, such as copper dioxide, iron dioxide, etc. They did not participate in the reaction in the form of ions. - The volatile substances (such as carbon dioxide gas, etc.) could not be dismantled. They were not in the form of ions. - Weak ions (weak acid, weak base, and water) could not be dismantled. For example, vinegar was a weak acid and existed in the form of molecules in the solution. - The hard to dissolve substances (precipitations) could not be dismantled, such as the precipitations of the sulfuric acid. - The non-eletrolyte could not be dismantled. The non-eletrolyte was not ionised in the solution, such as alcohol. - The weak acidic radical generally could not be dismantled (except for the HSO4-bisulfuric acid radical in the solution state, which could be completely dismantled in some cases). ###3. Remove the same ions He deleted the same ions on both sides of the equation and simplified the equation. ###4. Check the equation 1. It was to check if the reaction was true. 2. To check if the elements were conservative, the number of atoms of the same element on both sides of the equation had to be equal. 3. Check the conservation of charge. The total amount of charge on both sides of the equation must be equal.(The conservation of lost and gained electrons must also be paid attention to in the oxido-reduction reaction, but it is relatively easy to rewrite the ion equation in the middle school oxido-reduction reaction.) 4. Check if the ion symbol is correct. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reaction equation and phenomenon of iron and liquid water
The chemical equation for the reaction between iron and liquid water is: 3Fe+4H2O = high temperature = FeO +4H2O. Reaction phenomenon: Iron and liquid water will react at high temperatures to form Fe3O4 and hydrogen. From the perspective of material change, iron gradually underwent chemical changes during the reaction process, forming a black iron oxide-like solid, and at the same time, gas hydrogen was produced. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction equation for the decomposition of carbamine in junior high school chemistry
In junior high school chemistry, the equation for the decomposition reaction of ureas was: (NH2 <2>)<2> CO → NH2 <2>+<2> CO2 <2>. It should be noted that the decomposition reaction of ureas requires certain conditions to be carried out. Generally, it needs to be carried out at a higher temperature (150 - 190 ° C) and under basic conditions (which can be achieved by adding basic catalyst such as lithium and lithium). The basic conditions can provide the radical ions (oh2) to promote the decomposition reaction of ureas. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to write the reaction equation of sulfur and liquid mercury
The chemical equation for the reaction between sulfur (S) and mercury (Mercury) is: Mercury +S = HgS. This reaction can occur at room temperature. The process is the interaction between sulfur atoms and mercury atoms to form mercury sulfur (HgS) molecules. In this reaction, the valency of mercury changes from 0 to +2, and sulfur changes from 0 to-2. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to write the reaction equation of liquid and solid state
The writing of chemical equations had to be based on experimental facts and follow the law of conservation of mass. Whether liquid, solid, or gaseous substances participated in the reaction, the basic writing principles were the same. First, he had to determine the chemical formula of the reagents and products. If the reagent is a liquid substance, such as water (H <2> O) liquid, sulfuric acid (H <2> SO2) liquid, etc.; solid substances, such as iron (Fei) solid, calcium dioxide (CaCO2) solid, etc. The type of reaction, such as combination reaction, decomposition reaction, replacement reaction, or metathesis reaction, was specified. For example, iron (solid) and copper sulfuric acid (liquid, the solute in the solution is CuSO) undergo a substitution reaction, and the reaction equation is: When writing the equation, one had to pay attention to balancing the reaction equation, so that the types and numbers of atoms on both sides of the equation were equal, and also indicate the reaction conditions (such as heating, ignition, catalyst, etc.). If it was a reaction in a solution, one had to pay attention to the dissolution of the substance and the writing of the ion reaction equation (if required). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to write the reaction equation of alcohol in water
There were many types of alcohol, and different types of alcohol reacted differently with water. For example, alcohol (C2 H Ox) and water were mutually dissolved and did not undergo a chemical reaction. There was no reaction equation. However, for example, CH OH was also mutually dissolved and did not react in water. However, some special alcohol may have a weak reaction. For example, some polyhydric alcohol may have hydrogen bond interactions with water, but there is no typical chemical reaction equation to express it. So you have to tell me which alcohol is reacting in water so that I can accurately write down the reaction equation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Junior high school students write novels
I recommend " From the Lord of the Rings " by Deep Sea Old Cat. This was the infinite fantasy of the West. The male protagonist traveled to the Hobbit world to become Morgan, a soldier, and met Gandalf behind him. He had the system to increase the attributes of his soul power by killing powerful creatures. The writing style was suitable for web novels, and the rhythm and logic were not bad. Although the main character's goal was a little contradictory, it was overall good. The Hobbit had been written, followed by the Lord of the Rings and other worlds. " Myth: The Emperor of Heaven Doesn't Work Today " wasn't too bad either. It was written in the name of death. The main character had transmigrated into the Indian Mythology's Heavenly Emperor, Indra. In Indian Mythology, there would always be people who would fight the Heavenly Emperor after cultivating bitterly and obtaining blessings. He did not want to do it anymore. The story was humorous and popular. It was a work of a new race track. The author had a deep understanding of Indian mythology, and the updates were stable. The early stages were interesting, but the later stages were a little weak. There was also 'The Rippling Years of High School,' a ballad that had just been written. Returning to high school, the protagonist Lin Chu felt that her words were useless. She had to live her life in peace. The writing style was good, and it was comfortable to read. The Heart of Green Vine-Middle School Times, written by Qing Yan Lingxue, is also available. The school story was very youthful, with many characters, interesting stories, and profound writing. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
