What are the main elements in the 'hohman indiana christmas story'?

许多金属都能与氧气反应，但反应的难易和剧烈程度不同，这在一定程度上反映金属的活泼程度。 1. **镁和氧气反应** - 常温下（在空气中）：反应方程式为\(Mg + O_{2}=MgO\)，银白色镁条在空气中表面逐渐变暗，生成白色固体。 - 点燃时（在空气中或在氧气中）：反应方程式为\(Mg + O_{2}\stackrel{点燃}{=}MgO\)，剧烈燃烧，发出耀眼的白光，生成一种白色固体。 2. **铝和氧气反应** - 常温下（在空气中）：反应方程式为\(Al+O_{2}=Al_{2}O_{3}\)，银白色的表面逐渐变暗，生成一层致密的薄膜。 - 点燃时（在氧气中）：反应方程式为\(Al + O_{2}\stackrel{点燃}{=}Al_{2}O_{3}\)，剧烈燃烧，放出大量的热和耀眼的白光，生成白色固体。 3. **铁和氧气反应** - 常温下，干燥的空气：不反应;常温下，在潮湿的空气中铁与空气中的氧气和水共同作用下会生成暗红色疏松的物质--铁锈（主要成分\(Fe_{2}O_{3}\)）。 - 在氧气中点燃：反应方程式为\(Fe+O_{2}\stackrel{点燃}{=}Fe_{3}O_{4}\)，剧烈燃烧，火星四射，放出大量的热，生成一种黑色固体。 4. **铜和氧气反应** - 常温下，干燥的空气：不反应;加热时：反应方程式为\(2Cu + O_{2}\stackrel{加热}{=}2CuO\)，铜丝表面逐渐变为黑色。在潮湿的空气中\(2Cu + O_{2}+CO_{2}+H_{2}O = Cu_{2}(OH)_{2}CO_{3}\)，铜表面生成一层绿色物质。 5. **金、铂与氧气反应**：即使在高温下也不与氧气反应，所谓“真金不怕火炼”。 6. **钠和氧气反应** - 常温：反应方程式为\(4Na + O_{2}=2Na_{2}O\)（白色），切开的光亮的金属断面很快地变暗。 - 点燃：反应方程式为\(2Na + O_{2}\stackrel{点燃}{=}Na_{2}O_{2}\)（淡黄色），钠在空气中受热后先熔化后燃烧，发出黄色的火焰，生成淡黄色固体。 <a href="/?from=ask_words" style="color:red" target="_blank">点击前往免费阅读更多精彩小说</a>

Professional photographers preferred to use Apple phones for shooting mainly for the following reasons. First of all, the color reproduction of the iPhone was better, and it could accurately display the color of the scene. Secondly, the algorithm could make the photos have a larger tolerance, which meant that more light and dark information in the scene could be recorded, so that there was more room for adjustment during post-processing. Whether it was artistic expression or real scene restoration, high-tolerance photos were a necessary prerequisite. In addition, the new ProRAW photo format for the new Apple phone combined the RAW shooting function with Apple's deep calculation photography function. Not only did it provide all standard RAW information, but it also came with Apple image pipeline data. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
