What are the reactions and products of NH3---> N2 + H2 and balance this equation

What stress will shift the following equilibrium system to the left? n2(g) + 3h2(g) ⇌ 2nh3(g) adding more n2(g) adding more nh3(g) increasing the pressure of the system reducing the volume of the container

Ineed this asap part i: scientific method what is the difference between science and pseudoscience? what is the scientific method?

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.
