Take a look at the following reaction: heat + C2H2(g) + Ca(OH)2(aq) ↔ CaC2(s) + 2H2O(l).

Which side of the reaction is favoured based on entropy? Based on enthalpy? Explain why.

some of the qualities most frequently associated with the baroque are grandeur, sensuous richness, drama, vitality, movement, tension, emotional exuberance, and a tendency to blur distinctions between the various arts.

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).
