For the ammonia formation: N2(g) + 3H2(g) → 2NH3(g)
KC is 2.4x10-3 at 1000 K.

What are the values of Kc for the following:
a) 1/3N2(g) + H2(g) → 2/3NH3(g)
b) NH3(g) → 1/2N2(g) + 3/2H2(g)

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
