Prediction: The Cucl, crystal will dissolve in water. If we write the solvation process as a chemical equation, we can predict two possible outcomes:
a. Cuci
H2O Cu?* (aq) + 2 Cl(aq)
H2O Cu2+ (aq) + Cl2(9)
+ 9
.
b. Cuciz
In equation (a) Cl' ions remain dissolved in water whereas in equation (b) the chlorine molecule CI,
forms and leaves the solution as a gas. Which outcome do you expect (a or b)? Explain your reasoning.

Analyze how limestone is weathered and identify the features that are formed as a result of this dissolution

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.
