Answer:
c. 2,2-dichloropentane.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to firstly draw the structure of the reactant, pent-1-yne:

Now, we infer the halogen is added to the carbon atom with the most carbon atoms next to it, in this case, carbon #2, in order to write the following product:

Whose name is 2,2-dichloropentane.
Regards!
Answer:
the moon is the earths natural satellite.
Explanation:
A natural satellite is in the most common usage, an astronomical body that orbits a planet, dwarf planet, or small Solar System body (or sometimes another natural satellite). Natural satellites are often colloquially referred to as moons, a derivation from the Moon of Earth.
Answer:
The vapor pressure at 60.21°C is 327 mmHg.
Explanation:
Given the vapor pressure of ethanol at 34.90°C is 102 mmHg.
We need to find vapor pressure at 60.21°C.
The Clausius-Clapeyron equation is often used to find the vapor pressure of pure liquid.

We have given in the question


And
is the Universal Gas Constant.


Taking inverse log both side we get,

Answer: 600°C
Explanation:
This reaction is explained by Charles' law as the pressure is constant.
From the question, we obtained:
V1 = 67mL
T1 = 18°C = 18 +273 = 291K
V2 = 3V1 ( Vol is tripled) = 3x67 = 201mL
T2 =?
Applying the Charles' law,
V1 /T1 = V2 /T2
67/291 = 201 / T2
Cross multiply to express in linear form.
67xT2 = 291x201
Divide both side by 67, we have:
T2 = (291x201) /67
T2 = 873K
Converting to Celsius temperature, we have
T°C = K — 273
T°C = 873 — 273 = 600°C
