What is the difference between stating "the electron is located at a particular point in space" and "there is a high probability that the electron is located at a particular point in space"? choose all that apply. a. in the first statement we know where electron is. b. in the second statement, we are saying that we have no information about the position of the electron. c. in the second statement, we are saying that we know the probability of the electron being at a point, but we dont know exactly where it is. d. in the first statement, we cannot define the exact location of the electron.

Needthe meter is the standard unit for: 1) height 2) length 3) weight 4) mass

Use this information to determine the number of calends electrons in the atoms. which of the following correctly compares the stability of the two atoms? a) both are unreactive b) both are highly reactive c) a is unreactive and d is reactive d) a is reactive and d is unreactive

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.
