Question

Dinitrogen and dihydrogen react with each other to produce ammonia according to the following chemical equation:
$N_{2}(g)+H_{2}(g) \longrightarrow 2NH_{3}(g)$
(i) Calculate the mass of ammonia produced if $2.00 \times 10^{3}$ g dinitrogen reacts with $1.00 \times 10^{3}$ g of dihydrogen.
(ii) Will any of the two reactants remain unreacted?
(iii) If yes, which one and what would be its mass?

Answer 1

“Entropy” is a measurment of lack of thermal energy of any mechanical work system. It also represents the system's randomness. As randomness increases, the system entropy also increases. Entropy of the system is “directly proportional” to the randomness.

After hydration of $M{ g }^{ 2+ }$ ions are dissolved in water, it leads to “increase” in the randomness. Increase in the randomness increases the entropy. Therefore, after hydration increases the entropy.
