What is the new temperature when 10 L at 5 K is compressed to 4.00 L

lina2011 [118]

Answer: C

Explanation:

For this problem, we would use Charles's Law. We fill in what we are given and solve.

Charles's Law: $\frac{V_{1} }{T_{1} } =\frac{V_{2} }{T_{2} }$

$\frac{10 L}{5K} =\frac{4.00L}{T_{2} }$

$10T_{2}= 20$

$T_{2}=2K$

An organic compound that contains only carbon and hydrogen and a triple bond (all the other bonds are single bonds) is classifie

Basile [38]

Answer:

c. alkyne.

Explanation:

Hello there!

In this case, according to the attached file, it turns out possible for us to say that alkanes have only single-bonded carbon atoms, alkenes have two double-bonded carbon atoms and alkynes have two triple-bonded carbon atoms.

In such a way, according to the aforementioned definition, we infer that that an organic compound that contains only carbon and hydrogen and a triple bond (all the other bonds are single bonds) is classified as c. alkyne.
