In the important industrial process for producing ammonia (the haber process), the overall reaction is:

n2(g) + 3h2(g) → 2nh3(g) + 100.4 kj

a yield of nh3 of approximately 98% can be obtained at 200°c and 1,000 atmospheres of pressure.

what is the δh in kj of heat released per mole of nh3(g) formed?
50.2 kj
-50.2 kj
100.4 kj
-100.4 kj

- 50.2 kJ

Explanation:

From the data given, the heat released per 2.0 moles of NH₃ is - 100.4 kJ.The negative sign means that the reaction is exothermic and the energy is released.So, the ΔH in kJ of heat released per mole of NH₃ formed is (100.4 kJ/2) = - 50.2 kJ.

Answerbonded to an amino group(nh2);

According to arrhenius theory of acid and bases, an acid is a proton donor, while base donates hydroxyl ions. further, acid and base reacts to form salt and water.consider following example.hcl    +      h2o          →      cl-          +      h3o+here, hcl has donated a proton, hence it is an acid.now consider following reactionhcl      +      naoh            ↔      nacl      +        h2oin this reaction, hcl donates proton, hence it is acid. on other hand, naoh donates hydroxyl ion (i.e. hence it is a base.
