Answer:
Pot Q would contain more concentration of nitrogenous compounds than Pot P.
Explanation:
Plants require certain inorganic nutrients for their growth and development. One of these nutrients is Nitrogen. Nitrogen is an integral part of certain biomolecules and structures in organisms including plants e.g nucleic acids (DNA and RNA), Chloroplast in plant cells, Amino acids etc.
Plants, through their roots, absorb nitrogen in form of nitrogenous compounds like ammonium, nitrates etc. present in the soil. Certain bacteria in the soil help fix nitrogen into usable compounds by the plants, since plants cannot absorb nitrogen directly from the atmosphere.
In this case, Moin measured the concentration of nitrogenous compounds in a particular soil prior to planting. He then separated the soil into Pot P and Q. He planted sunflower seeds in Pot P and planted nothing in Pot Q. If he measures the concentration of nitrogenous compounds in both soil, he should observe that the concentration of nitrogenous compounds in Pot P has reduced due to absorption by the roots of plants grown in them. The concentration of nitrogenous compounds in Pot Q would now be more as there are no plans to absorb them.
Answer:
Sn^2+
Explanation:
A specie is diamagnetic if it has only paired electrons in its outermost shell. This implies that, we must first deduce the outermost electron configuration of the species. From that, we can now make our decision regarding which of the species is diamagnetic.
Bromine:
Electron configuration:
[Ar]4s2 3d10 4p5
Not diamagnetic
Chromium:
Electron configuration:
[Ar]4s1 3d5
Not diamagnetic
Phosphorus:
Electron configuration:
[Ne]3s2 3p3
Not diamagnetic
Tin II ion:
Electron configuration:
[Kr]4d10 5s2
Diamagnetic
