- A chemist fills a reaction vessel with 3.61 atm nitrogen (N,) gas, 8.64 atm oxygen (0,) gas, and 6.55 atm nitrogen monoxide (NO) gas at a temperature of 25.0° C. Under these conditions, calculate the reaction free energy AG for the following chemical reaction: N,(g) + O,(g) = 2NO (g) Use the thermodynamic information in the ALEKS Data tab. Round your answer to the nearest kilojoule. do Data HNO3 (1) -174.1 HNO3 (g) -133.9 Oxygen OH (aq) H20 (1) -285.8 H20 (g) -241.8 02 (9) H202 (1) -187.8 H202 (9) -136.3 Phosphorus Explanation Check P4 (s) 2021 McCAmmonia (NH3) is naturally produced through the decomposition of organic material as wellas being high in wastewater discharged to natural waters. In the environment it is oxidizedto form nitrite (NO2-), and nitrite is then oxidized to form nitrate (NO3-) in a process callednitrification. The balanced equations are given below:2NH3 + 3O2 → 2NO2- + 2H+ + 2H202NO2- + O2 → 2NO3-a) Assuming complete oxidation, what is the theoretical oxygen demand to convert100mg/L of ammonia to nitrate (i.e., how much oxygen is necessary)? Report youranswer as mg/L of O2.Answer: 376 mg/L O2b) This conversion process makes water more acidic. With reference to the equations forpH, explain why this occursThe extraction of aluminum metal from the aluminum hydroxide found in bauxite by the Hall-Héroult process is one of the most remarkable success stories of 19th century chemistry, turning aluminum from a rare and precious metal into the cheap commodity it is today. In the first step, aluminum hydroxide reacts to form alumina (Al,0,) and water: 2Al(OH), (s) Al,0; (s) + 3 H,0 (g) - In the second step, alumina (Al,0,) and carbon react to form aluminum and carbon dioxide: 2Al,0; (s) + 3C(s) → 4Al(s) + 3 CO, (g) Suppose the yield of the first step is 82.% and the yield of the second step is 69.%. Calculate the mass of aluminum hydroxide required to make 10.0 kg of aluminum. Be sure your answer has a unit symbol, if needed, and is rounded to the correct number of significant digits. x10
