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.

Late reaction of the notebook's right clickThe slow response of the laptop's right-click might be due to too many right-click options. You can try to delete some options by modifying the registration table, but modifying the registration table is risky. Please be careful. The specific operation was: [Win+R] Open the Run window, type [regedit], enter the key to enter the register editor, and then open: [Hong Kong_Classes_ROOT/Catalog/background/shelrex/ContextMenuHandlers/ContextMenuHandlers] to select the items to be deleted. You can also use a Mini programs to clean the right click, copy the following contents into the TXT file, and modify it to.bat format before running:
@ ECHO OFF
@ ECHO.

Many graphics cards would have one or more menu options after installing the driver. These functions were not practical and would slow down the pop-up speed of the right click. In particular, Intel's integrated graphics card had a very slow response speed, which seriously affected the user experience. Therefore, we recommend eliminating these menu options.

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.

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.

Bearing reaction force is the content of theoretical mechanics, right? Why?The reaction force of a support was a term in theoretical mechanics. It could also be called the restraint reaction force of a support. It was the support force of a support to the supported object, so the reaction force of a support was part of theoretical mechanics. In the analysis of theoretical mechanics, such as the analysis of the mechanical equilibrium relationship of the structure, the calculation of the support reaction force was an important part. Without theoretical mechanics as the basis, it was impossible to calculate the support reaction force and other structural mechanics related content.

The reaction of copper and sulfur to form red copper, right? WhyThe reaction of copper and copper sulfuric acid would not produce red copper.
When the reaction between the solution of sulfur dioxide and the solution of copper dioxide occurs, the first reaction between the solution of sulfur dioxide and water is an oxido-reduction reaction, which forms the reaction of sulfur dioxide and hydrogen. The reaction equation is [2Na +2H ^O = 2NaOx + H ^^]. Then, the double decomposition reaction between the lithium hydrogen and copper sulfuric acid occurs to produce copper hydrogen and lithium sulfuric acid. The reaction equation is [CuSO2 + 2NaO4 CuSO2 + NaSO2]. The general equation of the reaction between metallic Na and copper sulfuric acid solution is: [2Na + Cu2 + 2H2O = 2Na + Cu2 + H2O]. There would be no copper in the entire reaction process, so there would be no red copper.

The positive material of the primary battery must not participate in the reaction, right?This wasn't right. In the primary battery, the conducting material in the positive pole material sometimes only acts as a conductor and does not participate in the reaction, but the oxidiser in the positive pole will participate in the reaction. For example, the positive pole in the Alkaline Zinc-Manganese Dry Cell is made of Manganese Dioxid and Graphite. Manganese Dioxid (the oxidiser) is involved in the reaction, and the reaction formula is: Mn <2>+2H <2> O +2e <2>= Mn <2>+2H <2>.

The reaction of aluminum and sulfuric acid to form nitrogen, right? Why?The reaction between aluminum and sulfuric acid would not produce nitrogen. When aluminum reacted with concentrated sulfuric acid, it would form a dense layer of oxygen film on the surface, which would be passive and prevent the reaction from proceeding further. When the sulfuric acid was diluted, the reaction equation was: AI +4HNO3 = AI (NO3)3+NO → +2H2O. When the sulfuric acid was concentrated, the reaction equation was: AI +6HNO3 = heating = AI (NO3)3+ 3NO2 → +3H2O. It could be seen that the reaction product was nitrogen dioxide or nitrogen dioxide, not nitrogen.

What reaction does right lung upper lobe scabies have?The right upper lobe of the lung could have both general and local symptoms. The general symptoms included low fever in the afternoon, night sweats (sweating all over when sleeping or waking up, and the underwear was wet), fatigue, listlessness, weight loss, loss of appetite, rapid heartbeat (consistent with body temperature), menstrual imbalance, and so on. Local symptoms included coughing, expectoration, hemoptysis, chest pain (the location was uncertain, but it was often dull pain), difficulty breathing, and so on. However, it was impossible to confirm the diagnosis of lung cancer by simply relying on imaging to find signs that might be due to lung cancer in the upper lobe of the right lung (such as solid shadow or nodulus shadow, cavity shadow, calcium focus, bronchi narrowing or distension, etc.). It also needed to be combined with other examination results such as phlegm examination and pneumonin test to make a comprehensive judgment.
