Draw the product that valine forms when it reacts with excess CH3CH2OH and HCl followed by a wash with aqueous base. You do not have to consider stereochemistry. Do not draw organic or inorganic by-products. Draw the product in neutral form unless conditions are clearly designed to give an ionic product. Include cationic counter-ions, e. g., Na in your answer, but draw them in their own sketcher. Do not include anionic counter-ions, e. g., I-, in your answer.

Which of these properties, used alone, would be least useful in identifying most minerals? a. color b. luster c. streak d. density

Which step in naming unsaturated hydrocarbons is used for alkenes but not alkynes

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.
