Absorption with chemical reaction: h2s scrubbing with mea as shown in problem 3.22, scrubbing of hydrogen sulfide from natural gas using water is not practical since it requires large amounts of water due to the low solubility of h. s in water. if a 2n solution of monoethanolamine (mea) in water is used as the absorbent, however, the required liquid flow rate is reduced dramatically because the mea reacts with the absorbed hs in the liquid phase, effectively increasing its solubility. for this solution strength and a temperature of 298 k, the solubility of h. s can be approximated by (de nevers, 2000) puasi (19.4 pa)exp (1952: 25: ). repeat the calculations of problem 3.23, but using a 2n monoethanolamine solu- tion as absorbent.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

2b2t

explanation:

2b2t

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

it takes on an electronical energy
