For the reaction NH4Cl (s)→NH3 (g)  + HCl (g) at 25°C, ΔH = 176 kJ/moland ΔS = 0.285 kJ/(mol - K). What is the ΔG, and will this reaction be spontaneous in the forward direction?

169 kJ/mol; no

-91 kJ/mol; yes

91 kJ/mol; no

91 kJ/mol; yes

Answerrestate the main idea,essay or thesis, summarize the three subpoints of your essay, leave the reader with an interesting final impression;

So the main goal for the elements is stability which is a complete/full valence shell and typically the magic number for a stable element is 8 valence electron but not always. so elements to the left of the periodic table tend to be way less stable then those on the right, so the elements on the left are much more reactive.

Atomicwould be the answer

Um ask a different problem if you want me to answer
