Answer:
See explanation and image attached
Explanation:
Here attached are resonance forms of pyrrole and pyridine. The images were obtained from quora and researchgate respectively.
Now, we can see that in the resonance forms of pyrrole, the nitrogen atom in the heterocycle has a formal charge of +1. However, in the six membered pyridine hetrocycle, the nitrogen atom may have a formal charge of -1 or +1 as shown in the canonical structures attached. The structures in which nitrogen has a +1 formal charge in pyridine are comparable to structures obtained from pyrrole. These structures have less contribution to the structure of pyridine.
Answer:
La constante de equilibrio (K) se expresa como la relación entre las concentraciones molares (mol/l) de reactivos y productos. Su valor en una reacción química depende de la temperatura, por lo que ésta siempre debe especificarse.
Explanation:
The humidity of yesterday was grater than today`s there has been percipitation and also a lot of air pressure
Answer:
Basicity is the number of replacable hydrogens of an acid in aqueous or basic medium. Three –OH are present (attatched with P atom ) . These three –OH produces three H+ ions. Number of replaceable hydrogen ions in H3PO4 is 3
This picture sets a soothing scene, as the sunset lies over the trees. It is very calm outside because the wind is in no rush. It has to be winter because thy tree hath bare branches and the clouds settle down waiting for night. The moon is jealous because it can not create anything as beautiful.
