Which structure shows the correct electron arrangement in CCl4? A central upper C is single bonded to upper H above, below, and to the left, and single-bonded to upper C l to the right. The C l has three pairs of electron dots, above, right, and below. A central upper C is single bonded to upper C l to the top, bottom, and left; those upper C l atoms have three pairs of electron dots on the sides away from the bond. The C is also single bonded to an upper H to the right. A central upper C is single bonded to upper H above and below, and to upper C l to the left and right. The C l have three pairs of dots, above, below, and to the side opposite the bond. A central upper C is single bonded to upper C l above, right, left, and below. All the C l atoms have 3 pair of electron dots, on the three sides that do not have the bond.

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.
