a. list two safety issues regarding the use of ether.
b. what are the main components found in the receiving flask at the end of any steam distillation experiment?
a))1) inhalation of ether can causes drowsiness , respiratory diseases , and skin diseases , nervous system disorders.
2) due to highly flammable nature , there is a tendency of fire hazard .
b) steam distillation is a method used to separate the component which is more volatile and water immiscible . and these component is found in receiving flask of steam distillation .

Experiment #6 Ester Synthesis PRE-LAB ASSIGNMENT This pre-lab assignment is worth 5 points for this Experiment and should be completed on a separate page and turned in at the beginning of lab. 1. Read the experiment carefully 2. Safety Considerations: Summarize O safety and health hazards for working with glacial acetic acid, butanoic acid and petroleum ether. 3. Procedure: Summarize the procedure using a bullet list. Assume you are summarizing the procedure to a fully qualified chemist, i.e. don't include...
What is the SN2 reaction? How does Br attach to which carbon as
a nucleophile and why? Difference between Unimolecular or
Bimolecular? How NaBr and H2SO4 work in the
reaction? Why Water/Sulfuric Acid/Brine/Sodium
Hydroxide/Na2SO4 in Extraction? What does
each layer have inside in each step of the separation?
Please help. Due to corona, this is a theoretical lab and I am
very confused.

Remember in experiment 2 you used boiling chips; can the boiling sticks be replaced by boiling chips in this experiment? Explain your answer. Experiment2: Determination of Alcohol content of Wine by Fractional Distillation Introduction If a mixture of ethanol and water are warmed you might expect the more volatile (lower boiling) ethanol to boil first and then the water. This is not exactly true. As the mixture is warmed all the molecules within the flask will gain energy. In fact...

PROBLEM 1 A nickel-titanium alloy is. used to make components for jet turbine aircraft engines. Cracking is a potentially serious problem in the final part because it can lead to non-recoverable failure. A test is run at the parts produced to determine the effect of four factors on cracks. The four factors are A pouring temperature Btitanium content C = heat treatment method D amount of grain refiner used Two replicates of a 2 design...
