A new polyglycol complex, catena-poly [[(3,6-dioxaoctane-1,8-diol-κ4O)(nitrato-κ2O,O′)lead(II)]-μ-(nitrato-O,O′:O′,O′′)], [Pb(NO3)2(C6H14O4)]n, has been synthesized and structurally characterized by single-crystal X-ray diffraction and IR spectroscopy. The Pb atom ...
Pb(NO3)2 is soluble in water. Solubility of salts:Solubility of salts refers to the exact mass of a solute (salt) that will dissolve in 100 ml of water (solvent) at a specific temperature. It also gives explanations and inferences for the extent to which salt of various metals dissolve ...
Pb(NO3)2 reduced free radical release (hormetic effect) both in the whole thallus and in microalgae. However, only in TR9, the ROS production, chlorophyll autofluorescence and lipid peroxidation were dependent on NO. In conclusion, Pb hormetic effect seems to depend on NO solely in TR9, ...

桌上摆有两个相同的匀质小球A和B，桌面无摩擦，A和B间的碰撞是无摩擦的弹性斜碰。球很小，略去它的转动，但球也不是几何点，A球可以朝着B球心，也可朝着B球某个边缘部位打去。只要求A击中B后两球不与桌壁相碰，各自直接落入两个球洞，试问A与B分别可放在桌面上哪些位置?
