What is coexistence and what does coexistence mean?

Mass coexistence means that in a solution, two ions cannot combine to form gas, water, or precipitate.

That is, ions cannot react with each other, such as the formation of water, precipitation, and gas. Specifically, generally H and Ho cannot coexist, and there are others, especially H and NO3 can be considered as nitric acid, which has oxidizing properties and can react with some reducing ions, such as divalent iron.

Introduction

There are gases such as CO32-, SO32-, S2-, HCO3-, HSO3-, HS-, HS-, etc., volatile weak acids cannot coexist with H+ in large quantities.

There is precipitation such as Ba2+, Ca2+, Mg2+, Ag+, etc., which cannot coexist with SO42-, CO32-, etc. Mg2+, Fe2+, Ag+, Al3+, Zn2+, Cu2+, Fe3+, etc. cannot coexist with OH in large quantities. Pb2+ and Cl-, Fe2+ and S2-, Ca2+ and Po43-, Ag+ and I- cannot coexist in large quantities.

There are weak electrolytes such as OH-, CH3COO-, PO43-, HPO42-, H2PO4-, F-, CLO-, ALO2-, SIO32-, CN-, C17H35COO-, etc., which cannot coexist in large quantities with H+; Some acidic weak acid groups such as HCO3-, HPO42-, HS-, H2PO4-, and HSO3- cannot coexist with OH- in large quantities; NH4+ cannot coexist with OH- in large quantities.

Coexistence, co-existence or co-existence.

It refers to a harmonious and orderly existence.

To coexist means to bend something to exist together or at the same time as other things; Survive together and coexist with the position.

The condition for the coexistence of matter refers to the state in which two or more substances exist in the same space and they can exist with each other without interfering with each other or interacting with each other. The conditions for the coexistence of matter include the following aspects, in short, the condition of the coexistence of matter is an interrelated and mutually constrained system, and in order to achieve the coexistence of matter, it is necessary to meet the above conditions.

1. The interaction force between substances should be appropriate. If the interaction forces between substances are too large or too small, they will not be able to coexist or disturb each other.

2. The composition between substances should be appropriate. Different substances have different properties and chemical compositions, and if their composition is not suitable, it can cause them to not be able to coexist or interact with each other.

3. The environmental conditions should be suitable. Different substances will exhibit different properties and behaviors under different environmental conditions, and if the environmental conditions are not suitable, it will affect the coexistence and interaction of substances.

4. The spatial distribution between substances should be reasonable. The spatial distribution of different substances will affect their interaction and coexistence, and if the spatial distribution is not reasonable, it will lead to their inability to coexist quietly or interfere with each other.

In high school, it is believed that substances or particles can coexist in large quantities as long as they do not have chemical reactions. There are four common conditions that can generally react:

1. It can undergo the slag decomposition reaction, that is, one of the three that can generate precipitation, gas, and substances (weak electrolytes) that are difficult to ionize is the energy reaction, such as silver ions and chloride ions can form precipitates or hydrogen ions and hydroxide ions can generate water.

2. Redox reactions can occur: such as between ferric ions and iodine ions.

3. It can have a thorough double hydrolysis reaction (which can be learned in the second year of high school), such as aluminum ions and carbonate ions.

4. Complexation reaction can occur: such as ferric ions and cyanocyanide thiocyanide (SCN-) to form Fe (SCN) 3 and so on.

"Coexistence" pinyin: gòngcún, meaning co-existence; A certain thing exists together or at the same time as other things, and exists together and coexists with the position.

Sentence formation: 1. The rule of law and stability coexist, and integrity and civilization coexist.

2. Humans cannot coexist with this planet if they cannot coexist with other species.

3. The environment and human beings coexist, and development and protection are synchronized.

4. Co-existence and co-prosperity with companies that have dealings with them is the only way for enterprises to maintain long-term development.

5. People should coexist peacefully with each other, rather than the jungle.

Question 1: What does coexistence mean There are two versions of coexistence. The new version will overwrite the old version in general.

For example, there is a game version that can now install the game. A version of the version will be overwritten only of the version. But it won't coexist version.

The installation is here to stay...

Question 2: What does the term C mean to coexist??? Are you sure you got it right? Or did you just take the content of the Ministry of Xiangxun in a sentence, can you say that it comes from**?

Then there's shared memory.

Hope it helps.

Question 3: What does coexistence mean Coexistence is a relationship of coexistence and mutual non-conquest, which is equivalent to peaceful coexistence.

Question 4: What does it mean for ions to coexist and not coexist? Ion coexistence is a chemical reaction between anion and ion; Non-coexistence means that there is a chemical reaction between the anion and ion, and it is no longer the original substance!

Question 5: What does it mean to coexist in relationships? Eun: Okay, I understand what that means.

Question 6: What does WeChat coexistence version mean WeChat coexistence version Android version is a software that can support one mobile phone to install two WeChat, WeChat coexistence version Android version is independent of the official WeChat, you can log in to the second WeChat, the two client data will not affect each other, two login at the same time. Reference**:

Question 7: What does mobile QQ coexistence mean? The so-called QQ multi-version coexistence is to integrate the QQ of the 08,09,10 three versions of the QQ code together,Suitable for hanging multiple QQs at the same time,In fact, you don't need this,The same can be used with the official version,The official 08 and 10 versions can coexist,In addition, the coexistence version can not solve the problem of memory!

Thank you and Happy New Year

1. The meaning of coexistence: when something exists in conjunction with other things or in the same place; Laughing together, hiding and coexisting with the position.

2, Song Yeshi's "Preface to Uncle Huang Wen's Zhou Rites": "Wash the filth of the three evils, and raise the public heart of the future generations with the morality of life, although it is not a book and walks alone, it will still coexist in conjunction with other scriptures, and its merit is great." ”
