Can't you calculate the reaction rate in a pure liquid state? Right? Right?
Yes, the pure liquid state could not be used to calculate the reaction rate. Because the concentration of a pure liquid (not a solution) is treated as a constant, according to the calculation formula of the reaction rate,"v =" Delta c /"Delta t"("v" is the reaction rate,"(" Delta c "is the change in concentration,"("Delta t" is the time), the concentration is constant,"(" Delta c = 0 "), so the reaction rate cannot be calculated.

What is the reaction type of the reaction between ethene and pure liquid Bromine?
The addition reaction between ethene and pure liquid Bromine occurred. During the reaction, the weaker bond between the double bonds between ethene CH ^=CH ^was broken, and the addition of the two Bromine atoms formed CH ^Br-CH ^Br-CH ^Br1 (1,2 -dibromoether). The reaction type was the addition reaction of alkene. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to calculate the half-life with the first-order reaction rate
For a first-order reaction, the half-life can be calculated using the formula, where t_{1/2} represents the half-life, n represents the base n, and k represents the reaction rate constant. It can also be calculated using t_{1/2} = 0.693/k (where 0.693 is the approximate value of the value of the value). The reaction rate constant, k, can be determined by experiment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
True love is pure, right?
True love was not necessarily pure love. There were many reasons and motives for love, not just because the other party was beautiful or handsome, or because the two of them had common interests. There were many factors in love that could affect a person's emotions and behavior, such as social status, family environment, personal personality, interests, hobbies, values, and so on. Some people will show extreme loyalty and responsibility in love. They will give up everything for the other party and even sacrifice their personal goals and interests. However, this kind of behavior was not necessarily simple because it might make the other party feel pressured or even feel restrained and uncomfortable. True love should be based on mutual respect, understanding, and trust. Both parties should communicate honestly, set goals together, and support each other. At the same time, they should respect each other's privacy and freedom. Only in this way could love become a healthy, happy, and meaningful experience.
There is liquid in the right breast, what medicine is best to take?
If there was a discharge from the breast, the appropriate medication should be chosen according to the cause. If it was due to physiological reasons such as pregnancy or breast-feeding, there was no need for medication and it could return to normal on its own. If it was caused by breast proliferations, it could be treated with traditional Chinese medicine such as Rubixiao. If there is a bacteria infection in the breast duct ectasia, you can choose antibiotics such as amoxicilin; if the symptoms are serious and the level of estrogens is abnormal, you can choose tamoxifen for anti-hormone therapy, and if necessary, you can choose steroids such as dexterity. If it was breast cancer, the drugs needed to be selected according to the specific molecular type, such as taxol, doxobin, etc., and anti-estrogens such as tamoxifen might also be used. However, there are many reasons for breast discharge. After the symptoms appear, it is recommended to go to the hospital in time to complete the examination. After the cause is confirmed, strictly follow the doctor's advice and take standardized treatment. Don't use medicine by yourself. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Why can't the reaction rate be calculated in solid state?
The concentration of the solid was regarded as a constant. According to the reaction rate calculation formula v = Delta c/Delta t (v is the average rate, Delta c is the concentration change, and Delta t is time), since the concentration of the solid was constant, the concentration change was zero, so the reaction rate of the solid could not be calculated by conventional methods. Moreover, when reacting between solid substances, the contact area between the molecules of the reagents was small, unlike in solution where the contact between the molecules of the reagents was sufficient and the chance of the molecules meeting was small. The reaction rate was slow and difficult to calculate using the conventional reaction rate concept. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
This could be the ceiling of pure desire, right?
He recommended a few novels. "I asked you to build the Great Wall, but you built an immortal empire and ascended?" An Eastern fantasy novel written by One Dream In Nine Autumns. Li Ye had crossed over to the Immortal Cultivation World and inherited a dying country to become the monarch. He worked hard to govern the country, farming and cultivating wonders, such as the Great Wall and Zhai Xing Lou. As he cultivated the wonders, the whole country would ascend. In the Mood for Love was an urban supernatural novel that I was thinking of, so I was writing. Lucky Boy's body had mutated and gained superpowers. Fame, wealth, and beautiful women were all here. He had to face all kinds of temptations. This book was a fantasy novel that was out of touch with reality. It was full of truth, kindness, and beauty. There were also related works such as " You Can't afford to play this game " and " Don't Go to College." " Douluo's Heroes of the Today ", a light novel written by Feng Ao in the South. The Three Dragon Kings of the Douluo Continent were legendary. There were characters such as the transmigrator male protagonist, Wei Mingshang. When the Douluo Continent faced many crises, heroes were born. " Men's Charm in the Portable Space ", a modern romance novel written by Don't Call Me Niu. The female protagonist felt that love was boring and troublesome. With a portable garden, she cultivated and farmed. " The Peaceful Space of Happiness " was a modern romance novel written by An Jing of the Night.

Molar reaction energetics change with temperature, right?
The standard mole of a chemical reaction changed with temperature. However, in engineering chemistry, it was generally believed that the change in the temperature did not change. Although most of the standard mole change in the table was at 298.15K, it could also be used for other temperatures (strictly speaking, the difference in the change in the temperature was different, but it was generally not greater than 5%, and this difference could be ignored). When Kirchhoff's formula was used to calculate the heat of reaction at different temperatures, if there was no phase change for each substance in the entire temperature range, it could be calculated directly. If some substances had a phase change, it could not be directly calculated using the definite integral or the uncertain integral. It needed to be calculated in sections. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The reaction between acid and base must be a neutralizing reaction, right? Why?
The reaction between acid and base was not necessarily a neutralizing reaction. Neutralization reaction was defined as the reaction between acid and base to form salt and water, but the reaction to form salt and water was not necessarily a neutralizing reaction. For example, the reaction between some oxides could also form salt and water, but it was not a reaction between acid and base. Therefore, it could not be determined that the reaction between acid and base was a neutralizing reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Why don't we use the solid state to represent the reaction rate?
The concentration of the solid was regarded as a constant. Changing the amount of solid had no effect on the chemical reaction rate, so the reaction rate was not expressed by the solid. In addition, the chemical reaction rate is usually expressed by the change in the concentration of the reagent or the product in a unit of time. The particles in the solid are tightly interlocked and are not easy to move, so their concentration in the reaction is constant. For reactions that involve solid, the chemical reaction rate is generally not expressed by the solid. The chemical reaction rate is related to its surface area, and has nothing to do with the amount of substance. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
