Molarity and Ion Concentrations: In a textbook it says molarity measures a molecular compound as it exists within the solution (Example: 1.0M C6H12O6 indicating that it contains 1.0 mol C6H12O6 per liter of solution). However, with an ionic compound it measures it before it dissolves (Example: 1.0M CaCl2 solution contains 1.0 mol Ca and 2.0 mol Cl). Why is it like this? Can’t glucose be broken down the exact same way (6 mol C, 12 mol H, 6 mol 6)?

The table describes how some substances were formed substance 19 description formed by boiling pure water formed by combining three hydrogen atoms to every nitrogen atom formed by adding 5 g of sugar to 1 l of water formed by compressing carbon under high pressure based on the given descriptions, which substance is most likely a mixture?

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.
