An experiment is designed to test what color of light will be activated photoelectric cell best. the photocell is set in circuit that "clicks" in response to current. the faster the current, the more clicks per minute. in the experiment, the number of clicks in one minute is recorded for each color of light shining on the photocell. to change the color of light, a different color of cellophane is place over the same flashlight and the flashlight is then located a specific distance from the photocell.
which of the following would be the best hypothesis for this experiment?
a.) red light will activate the photocell to the highest degree.
b.) if photoelectric cell respond better to short wavelengths of light, the red light should activate it the least and blue the most.
c.) photoelectric cells are affected by different wavelengths of light.

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.
