Ammonia (NH3) is a weak base. Melting point of ammonia is -78 Celsius degrees and boiling point is -33 Celsius degrees. Therefore, pure ammonia appears in gaseous form in room temperature. a) Preparation of ammonia Gaseous ammonia (NH3) can be prepared by a reaction where Hydrogen gas (H2) and Nitrogen gas (N2) reacts. Write a reaction equation to this reaction. Balance the reaction equation if needed. b) Behavior of gases Explain the diffusion of gases. c) Change of temperature The closed container filled with gaseous ammonia is moved from room temperature into a freezer. The temperature on freezer is -35 Celsius degrees. Explain shortly on your own words, what kind of changes does the cooling cause and why.
