- Ammonia (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 occursAtomic Weight of a Metal from Hydrogen Gas Production Objective: To produce hydrogen gas by reaction of a metal with an acid. To use the ideal gas equation to determine the atomic weight of the metal. Background: Many metals react with hydrochloric acid to produce hydrogen gas and metal ions. In this Lab you will use Magnesium: Mg(s) + 2 H+(aq) → H2(g) + Mg2+(aq) The moles of hydrogen gas produced can be determined using the Ideal Gas equation, PV = nRT. From the moles of hydrogen and the stoichiometry (reacting ratios) of the reaction, it will be possible to calculate how many moles of metal reacted. From this, the atomic weight of the metal will be determined. When a gas is collected over water, it becomes saturated with water vapor and the total pressure of the mixture in the buret equals the partial pressure of the gas plus the partial pressure of the water vapor. The partial pressure of water vapor depend on temperature. Finally, the total pressure of gas…FIND THE PERCENTAGE YIELD, and include the moles of the reaction (part 2)
