The elements in Group 1 have similar chemical properties. Descnbe one chemical reaction which shows that lithium, sodium and potassium (using a group 7 element)
react in the same sort of way.
You should say what you would react them with and what substances would be
produced.​

Which term describes a fracture in the earth at which land stays in the same place? a. joint b. fault c. split d. hinge

What are the first three quantum numbers for the electrons located in subshell 2s?

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.
