In your experiment you used .557 g of Cu metal to start your first reaction. At the end of the experiment you isolate .581 g of solid Cu. Which of the following is a likely explanation for this result. (Choose all that apply) a) you did not give your Cu crystals enough time to dry completely b) The balance must be broken c) The experiment was a success d) there was some unreacted Zn mixed in...

Principles of Inorganic Chemistry! Week 5 Effect of Temperature on Solubility of a Salt In this experiment, you will study the effect of changing temperature on the amount of solute that will dissolve in a given amount of water. Water solubility is an important physical property in chemistry, and is often expressed as the mass of solute that dissolves in 100 g of water at a certain temperature. In this experiment, you will completely dissolve different quantities of potassium nitrate,...

Experiment Write Up Proposal You will write up a synthesis procedure for one reaction that could be potentially run in a face- to-face Chem 2321 lab session. Your proposal will include an introduction and procedure. The procedure will include step-by-step instructions for running the reaction (including reaction monitoring), work-up. (product isolation and purification), and analysis (characterization). You will need to include sample calculations for percent yield and provide sample spectra analysis. You must upload your proposal as a single document...
