In 1909 Fritz Haber discovered the workable conditions under which nitrogen, N2(g), and hydrogen, H2(g), would combine to
produce ammonia. The conditions included medium temperature (-500°C), very high pressure (-351kPa), and an iron catalyst.
The reaction is represented by the equation:
N2(g) + 3H2(g) - 2NH3(g)

HOW MANY MOLES OF NITROGEN ARE NEEDED TO PRODUCE 1.20 miles of ammonia gas?

A. 0.60 mol N2

B. 1.21 mol N2

C. 1.67 mol N2

D. 2.40 mol N2

answer: i would say b.

explanation:

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
