Hexane is a colourless liquid with a characteristic smell that reacts with chlorine gas in the presence of a catalyst. Chlorohexane is a liquid compound that is formed through the substitution of one hydrogen in the hexane molecule with chlorine. Write the chemical equation for this reaction and explain if it requires balancing. Hydrogen chloride gas is also a product of this chemical reaction. Note: ignore the presence of the catalyst.
One way the U.S. Environmental Protection Agency (EPA) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. Any chloride anions in solution will combine with the silver cations to produce bright white silver chloride precipitate. Suppose an EPA chemist tests a 250.mL sample of groundwater known to be contaminated with iron(III) chloride, which would react with silver nitrate solution like this: FeCl3(aq) + 3AgNO3(aq) → 3AgCl(s) + FeNO33(aq) The chemist adds 81.0mM silver nitrate solution to the sample until silver chloride stops forming. She then washes, dries, and weighs the precipitate. She finds she has collected 4.4mg of silver chloride. Calculate the concentration of iron(III) chloride contaminant in the original groundwater sample. Round your answer to 2 significant digits.

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.
