Response: The energy and that is produced by an atom in gaining an electron from outside atom or ion to form damaging ion (or anion) is called electron gain enthalpy (∆egH).
Clarification: When resistors are linked in series, same level of latest flows via each one of these.

(b) Enzymes — An enzyme can be a protein that functions on a particular material to form a certain stop product. It ideal acts at a specific temperature and pH.
Therefore, a partially positively billed hydrogen atom kinds a bond with one other much more electronegative atom. This bond is named a hydrogen bond. Hydrogen bond is much better than the van der Waals forces.
The two ionisation enthalpy And that i electron obtain enthalpy are usually expressed with regard to the ground point out ofan atom only.
