The sun has been up for several hours, and it has been shining on these trees. What can the trees do because they are in sunlight? What does this mean for the number of energy storage molecules in the trees? The trees can . . .
a give off carbon to the air. Giving off carbon allows them to make energy
storage molecules.
b give off carbon to the air. Giving off carbon uses up energy storage
molecules.
c take in carbon from the air. The carbon is used to make energy storage
molecules.
d take in carbon from the air. The carbon is used to break down energy storage molecules.

2. These goats are eating grass on a sunny day. What is happening to the carbon in the air around the living things on the mountain? Is carbon moving into the air, moving out of the air, or both?
a Carbon is only moving into the air; it is not moving out of the air. b Carbon is moving into the air and out of the air at the same time. c Carbon is not moving into the air; it is only moving out of the air. d With this information, there is no way to know for sure.

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.
