” he asked, wrinkling his nose in___. “But it’s almost one already.”对纪录片进行诗意表达在历史上早有实践，纪实美学的实践者弗拉哈迪拍摄的纪录片《北方的纳努克》并不是单纯地记录现实生活，而是大胆地把真实的生活画面通过创作者的想象与诗意完美地结合起来，使得影片具有强烈的感染力。( ）
What is the solubility of lead bromide at 25oC? (Ksp = 4.6 x E−6) Solubility The relation among solubility and solubility product constant (Ksp) defines the solubility of slightly ionic substances. Solubility is measured in number of moles per liter (mol/L). Answer and Expla...
