What is the name of the following chemical formula Cr(BrO_3)_2? What is the chemical formula for oxygen? What are the rules for naming covalent compounds? What is the name of the compound with the formula (Nh4)2SO4 ? What is the compound name of Pb(NO3)2?
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, ...
It seems that Pb(NO3)4 is unstable; the most known lead nitrate is Pb(NO3)2. But if Pb(NO3)4 could be stable enough to react as the chemical equation shows, this shows that: 1 mole of Pb(NO3)4 + 4 moles of KI = 1 mole of PbI4 + 4 moles of KNO3. Or 1 mole of Pb(NO3...

Cd, Cr, Pb, and Hg, Desulfovibrio gigas and Pseudomonas putida have also been reported to lessen the Ur (uranium) levels. Bacterial cells possess various binding surfaces for several metal cations and have metal hindrance phenotypes that advocate their utilization for environmental conservation. ...
in vitro pollen germination Pollen grains from open male flowers were lightly swept into the pollen germination medium [15% (w/v) sucrose, 0.01% (w/v) boric acid, 1 mM Ca(NO3)2, and 0.5% (w/v) agar, pH 6.5] using a soft brush54. After being cultured in light and humid at 28...
