The equation 2n2(g) + 3h2(g) = 2nh3(g) + energy shows the
formation of ammonia from nitrogen and hydrogen.
what effect does increasing the pressure have on this equilibrium? hint: which reaction produces fewer gas molecules?

Bthats what im doing to and i figured it out it is b

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).
