  • O2是什么气体 - 百度知道
    氧气 (氧元素形成的一种单质) 编辑 同义词 O2一般指氧气(氧元素形成的一种单质) 氧气(oxygen),化学式O2。化学式量:32 00,无色无味气体,氧元素最常见的单质形态。熔点-218 4℃,沸点-183℃。不易溶于水,1L水中溶解约30mL氧气。在空气中氧气约占21% 。液氧为天蓝色。固氧为蓝色晶体。常温
  • What is the difference between O O2 - Chemistry Stack Exchange
    The common confusion here is that two very different things have the same name is a free oxygen atom and 2 is two oxygen atoms chemically bound to form an oxygen molecule There is no common analogy for , but 2 is called nitrogen, 2 is hydrogen and 2 is chlorine, each having the same name as that of their constituent elements So, to reiterate, the difference between oxygen and oxygen X2 2 is
  • O2·-这个超氧阴离子自由基的点·是什么意思?-表示什么意思?2应该是下角标吧?_百度知道
    O2·-中的"·"符号表示一个特殊的化学实体,即超氧阴离子自由基,它带有单个电子。这里的"-"表示它带有一个负电荷。"2"作为下标,表明氧原子的价电子配置。自由基的特点在于分子结构中存在一个不配对的电子,而在这个O2·-中,这个不稳定的单电子被标注在 (π*2pz)1的位置。分子轨道的描述中
  • 氧根的种类有哪些(过氧根·超氧根什么的) - 百度知道
    氧根阳离子:O2PtF6 O2−(超氧根),是氧气分子的单电子还原产物,其性质活泼,易与多种大分子物质结合而使其失去活性。 如HO2 超氧酸。 O22−(过氧根),结构为-O-O- 的二价阴离子,同样性质活泼,易发生歧化反应,既可被氧化,又可被还原。
  • O2·-这个超氧阴离子自由基的点·是什么意思?-表示什么意思?2应该是下角标吧?_百度知道
    O2·-这个超氧阴离子自由基的点"·"是什么意思?"-"表示什么意思?"2"应该是下角标吧?2是下标没错,- 表示带一个负电。 · (点)强调这个阴离子中存在一个单电子,这也是自由基的标志
  • How does O2- have the largest radius - Chemistry Stack Exchange

  • 乙醇催化氧化反应方程式 - 百度知道
    乙醇完全燃烧的方程式: C2H5OH+3O2→2CO2+3H2O (条件为点燃) 乙醇的催化氧化的方程式: 2CH3CH2OH+O2→2CH3CHO+2H2O (条件为催化剂) (这是总方程式) 乙醇发生消去反应的方程式: CH3CH2OH→CH2=CH2+H2O (条件为浓硫酸170摄氏度) 两分子乙醇发生分子间脱水:2CH3CH2OH→CH3CH2OCH2CH3+H2O。
  • Whats the difference between 2O and O2 [duplicate]
    I just saw something in a chemistry lesson what got me confused What is the difference between $\\ce{2O}$ and $\\ce{O2}$? Thanks for the help!
