The colorless gas dinitrogen tetroxide decomposes to the brown coloured air pollutant nitrogen
dioxide and exists in equilibrium. A 0.125 mol sample of dinitrogen tetroxide is introduced into a
1.00 L container and allowed to decompose at a given temperature. When equilibrium is reached
the concentration of the dinitrogen tetroxide is 0.0750 mol/L. What is the value of Ke for this
reaction? (Use ICE)

These questions are based on the attached photo. the experiment is about burning magnesium metal with oxygen. 1. write the balanced chemical equation for the reaction you are performing. 2. calculate the mass of magnesium metal used in each trial. o trial 1: o trial 2: 3. calculate the actual yield of magnesium oxide for each trial. o trial 1: o trial 2: 4. magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. o trial 1: o trial 2: 5. determine the percent yield of mgo for your experiment for each trial. o trial 1: o trial 2: 6. determine the average percent yield of mgo for the two trials. your company currently uses a process with a similar cost of materials that has an average percent yield of 91 percent. if the average percent yield of this process is higher than that, this could save the company money. what is your recommendation to the company? support your recommendation using your data, calculations, and understanding of stoichiometry gathered from this lab.
