Homework Answers
The chemical spill contained 3,3-dimethylbutan-2-amine and heptanoic acid dissolved in hexane.
hence a 3,3-dimethylbutan-2 -amine , heptanoic acid are the solutes which were described

In this lab you are performing your first organic synthesis and safety information on all the materials you are using must be obtained. Companies are required to provide material safety data sheets (MSDS) for chemical compounds they sell. Please examine the MSDS for salicylic acid, available here. You will find GHS pictograms within the sheet that summarize the main hazards of this compound. The pictograms are essentially the same as the symbols on WHMIS labels, available here for reference. Based...

Question 6 (1 point) In your pre-lab, you were asked to determine the concentration for a 25.00 mL sample of acetic acid, CH3COOH (K= 1.8 x 10-5) of unknown concentration. Suppose you now repeat that same titration, using another 25.00 mL sample of that same unknown acetic acid and the same concentration of NaOH as a titrant. However, before you start titrating, you add an additional 100 mL of water to the flask containing our sample of acid. Everything else...

PART II: REACTIONS: Here is another different" question. Pretend you have been asked by me to put together a bunch of one-step reactions WITH starting materials (your choice), reagents and answers to help me with writing a final exam. For example: let's say I ask you to give an example of a free radical chlorination with a non-cyclic compound. Below would be your answer. As I am pretty sure you can figure out, there are millions of...

I just need help with the question #5-6
4. As you are an intelligent chemist and you've been doing this long enough to understand some fundamental aspects of safety when mixing/cooking chemicals etc., you decide before you begin this process, to place your reactants and the associated glassware under the vacuum hood just to be on the safe side. Based on your chemical equation above, is there a gas emanating from this reaction and if so, what gas is going...
