Examine the scenario.

aarav is studying a reversible reaction at chemical equilibrium in which the forward reaction is an exothermic reaction and the reverse reaction is an endothermic reaction. after making his initial observations, aarav cools the reaction, which removes thermal energy.

based on his knowledge of le châtelier's principle, what can aarav predict will occur?

the system will try to balance the change by shifting toward the endothermic reaction, and the rate of the reverse reaction will increase.

the system will try to balance the change by shifting toward the exothermic reaction, and the rate of the reverse reaction will increase.

the system will try to balance the change by shifting toward the endothermic reaction, and the rate of the forward reaction will increase.

the system will try to balance the change by shifting toward the exothermic reaction, and the rate of the forward reaction will increase.

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.
