Nitric acid is often manufactured from the atmospheric gases nitrogen and oxygen, and hydrogen prepared by reforming natural gas, in a two-step process. In the first step, nitrogen and hydrogen react to form ammonia: N2(g) + 3 H2(g) 2 NH3(g) In the second step, ammonia and oxygen react to form nitric acid (HNO, and water: NH3(g) + 202(g) → HNO3(g) + H,O(g) Suppose the yield of the first step is 71.% and the yield of the second step is 62.%. Calculate the mass of hydrogen required to make 3.0 kg of nitric acid. Be sure your answer has a unit symbol, if needed, and is rounded to 2 significant digits.

into the book. Write a concise definition of each, using examples as appropriate.

Consider each of the following monomers and predict if it would likely undergo radical, anionic, or cationic addition polymerisation. Then, in the space provided below, draw the electron pushing mechanism for the initiation and the first propagation steps of the monomer that you chose for each (the catalyst is provided for you). Then draw what the growing polymer chain looks like and briefly indicate why you chose that monomer to undergo the selected type of polymerisation (hint: consider concepts such as electron donating group, electron withdrawing group, resonance, and hyperconjugation!)

Please show all work! Choices are shown in second picture.
