The conditions that cause free radical reactions
The conditions that cause a free radical reaction generally include light, heat, radiation, or other free radical initiator (such as Peroxides, certain special metal ions, etc.). Acid, base, and other substances had no obvious effect on the free radical reaction. Common free radical initiator conditions included free radical initiator, heating, or light. In addition, there were also methods such as thermal radiation and single-electron oxido-reduction. It could also be directly heated by light, high-energy radiation, plasma, and microwave to initiate a free radical reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Cause and effect, cause and effect
In Buddhism, karma referred to the combination of the main conditions (cause) and secondary conditions (fate) for the creation of things. Cause is the key factor in the birth of things, and fate is the auxiliary factor. Both of them have certain results. Everything in the universe followed the law of causality. Cause was the cause, and effect was the result. However, the formation of effect was also affected by fate. Cause was like the starting point of the development of things, and effect was the end point. Fate was like the runway, wind direction, weather, mood, and other subjective uncontrollable conditions and environments, determining the specific direction from cause to effect. All things in the world gather because of karma and disperse because of karma. For example, the encounter between people was a kind of fate. Any small change in factors could affect the outcome, making the encounter or other events impossible. From a more macro perspective, all dharmas were born and destroyed by karma. When karma is sufficient, things are produced. When karma dissipates, things disappear. This process reflects the concept of "emptiness of nature", that is, things with karma and harmony have no fixed and unchanging nature. "Fairy Dream of Tang Shi: Fate of Peony" is equally wonderful.

The reactions of acid, base and salt are all metathetical reactions
Not all reactions between acid, base, and salt were metatheses. In junior high school chemistry, the reaction of acid and metal to form salt and hydrogen, such as 2AI +3H ^SO = AI ^(SO)+3H ^^, this reaction is not a metathesis reaction. Alkali reacted with non-metallic compounds to form salt and water, such as 2NaOx + CO2 = Na Chi CO2 + H Chi O, which was also not a metathesis reaction. The reactions of neutralizing acid and base (acid + base = salt + water), acid and salt (acid + salt = new acid + new salt), base and salt (base + salt = new base + new salt), salt and salt (salt + salt = two new salt), and metal oxide-acid (acid + metal oxide-salt + water) were all metathetical reactions. Moreover, the metathesis reaction had to meet certain conditions. The reagent had to be dissolved in water or acid, and the product had to be either one or two of the three substances of precipitations, gas, and water. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
