You are a well-known chemist in the town. Your close friends
organize a science fair in their school, and they invited you to share your expertise with
their young science explorer. You've decided to design using multimedia, demonstrations,
or models, a representation or simulation of any two of the following: a. atomic structure;
b. gas behavior; c. mass relationships in; and d. reactions, for them to grasp what you are
going to teach. Your output must show originality, content, polish, time management,
and selection of materials. It will evaluate by your colleague and a representative of the
Department of Science and Technology.

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
