How many moles of hydrogen are needed to completely react with 2 moles of nitrogen

One chemist claims that a new compound will inhibit the growth of a virulent strain of bacteria. When a second chemist from a different laboratory tests the compound against the same bacterial strain, the bacteria grow at their normal rate.

In an ionic compound, the size of the ions affects the internuclear distance (the distance between the centers of adjacent ions), which affects lattice energy (a measure of the force need to pull ions apart), which affects the enthalpy of solution.
