Tallahassee was established as the capitol of Florida because it was between Pensacola and St. Augustine. The distance from Pensacola to Tallahassee is 190 miles. The distance from Tallahassee to St. Augustine can be represented as (5x + 5) miles. The distance from Pensacola to St. Augustine can be represented as (9x + 35) miles. Is Tallahassee the midpoint of Pensacola and St. Augustine?

i know that the percentage of acetic acid is computed as the volume of soduim hydroxide times its normality equals the number of milligram equivalents of acetic acid neutrilized. The equivalence of acetic acid is 60.0mg or .060g. the 10mL sample of vinegar weights 10.05g. and the volume of sodium hydroxide is 12.54 mL. So how can i calculate the percentage of acetic acid? also i know that vinegar is essentialy a dilute solutin of acetic acid in water, and the law requires that vinegar be at least 4% acetic acid by weight.

We would like to begin building a high-psi pneumatic air cannon for tennis ball launching. Because of the high psi levels (>500psi), we would like to have a remote connected by wire to activate the burst valve. We will also be pressurizing by remote line feed as well so we are at a safe distance in case of rupture.

What type of valve should I look for at the hardware store to do this with, and what sort of electronic means could actuate this valve effectively on 12v power?

I mean we've lived with them for millions of years and we havn't gone extinct yet. The bacteria aren't as harmful as the media makes them look. And if we try to sanitize everything that just makes the bacteria problem worse because then we don't build up an immunity to them and they build up an immunity to out antibacterial cleaners. Yes we should sanitize some things like doctors before they go into surgury or if we are extreamly dirty. But we also need bacteria, even harmful bacteria, because e-coli helps us digest our food, and harmful bacteria makes us stronger. So all I'm saying is people don't have to worry about bacteria so much, we've lived with them for millions of years.

A chemistry student prepares the Tollens reagent by adding 1mL of aqueous silver nitrate solution and 1mL of 10% NaOH solution.
Then he adds 10mL of 10% ammonia solution and the precipitate dissolves.
After adding 3 drops of unknown, no silver mirror is formed.
What does that result indicate?

Select the best explanation from those shown.

a. To test properly, the solution would have to be heated.
b. A precipitate will NOT form if too much ammonia is added.
c. The wrong solutions were used to prepare the reagent.
d. The solution was prepared correctly and the unknown is NOT an aldehyde.
