The fluorine ion, F, has one more electron than a neutral fluorine atom. a) How many pea-halves do you need?
b) Fill the sublevels in the correct order for the fluorine ion and write the electron configuration for the charged atom.

Which object forms when a supergiant runs out of fuel? a red giant a black hole a white dwarf a neutron star

Write a paragraph that provides examples of each stage of volcanic activity, a description of the volcano, and facts about each stage.

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.
