How much amount of Oxygen will be available by heating 66.2 gram of Lead Nitrate |
|
Answer» How many oxygen are there in lead (II) nitrate?Well, you got Pb2+(NO−3)2 …i.e. a NEUTRAL salt formed from Pb2+ ion … and TWO equiv of nitrate ion … NO−3 … And so you got 6 oxygen ATOMS in the lead nitrate formula unit …The Lewis structure of nitrate ion is INTERESTING because 3 of the 4 atoms bear formal charge…. i.e. O=N+(−O−)2 …. nitrogen is quaternized, and BEARS a formal positive charge, and 2 of the oxygen atoms bear a negative charge, to GIVE an anion with a single negative charge …. of course the charge is distributed by resonance… GIVEN that the ionic charge is somewhat well distributed, many NITRATES salts have considerable water-solubility, and ALSO some solubility in more inert solvents. Nitrate salts, however, tend NOT to be used as inorganic precursors (as halide salts DO tend to be so used) given that the nitrate anion is OXIDIZING, i.e. a N(+V) centre…Explanation:I HOPE ITS HELPFULL FOR YOU....PLZ MARK ME AS A BRAINLIEST........ |

The second line in Paschen series corresponds to an electronic transition between which Bohr orbit in hydrogen? |
|
Answer» Line of Paschen Series :Always remember the following informations:In case of Paschen Series, the electron will always DESCEND from a higher orbit to a lower orbit with PRINCIPAL Quantum Number = 3.That means the lower orbit will be n = 3.Now, the first line in Paschen Series corresponds from n = 4 to n = 3 , with the highest wavelength of ELECTROMAGNETIC radiation.So, second line in Paschen Series will be from:n = 5 to n = 3. Hope It Helps. |
