A pilot checks for water in the gas before flying a small airplane. How does she do it?
| A. | Drain a little bit of gas from the bottom and look for two layers. |
| B. | Taste it. |
| C. | Shake the wings. |
| D. | Pipet a sample from the top of the tank and look for two layers. |
| E. | Check the oil. |
Homework Answers
Since water has more density than oil, it will be at the bottom of the tank.
So, she can take a small sample from bottom of the tank and look for 2 layers.
One layer is of water and other of oil

please help with how the flow chart will look like? thank
you!
Synthesis of n-Butyl Bromide Purpose of the Experiment: In this week's experiment you will be synthesizing n-butylbromide (IUPAC 1-bromobutane from 1-butanol and a concentrated acid via a nucleophilie substitution reaction. It is important to know that alcohols dehydrate to form alkenes in the presence of strong inorganic acids, so care must be taken in this experiment not to heat the reaction too vigorously else an elimination reaction may...
