The heat of vaporization of 1-pentanol is 55.5 kJ/mol, and its entropy of vaporization is 148 J/K.mol. What is the approximate b
____ [38]

Answer:

Approximately 100 °C.

Explanation:

Hello,

In this case, since the entropy of vaporization is computed in terms of the heat of vaporization and the temperature as:

\Delta S_{vap}=\frac{\Delta H_{vap}}{T}

We can solve for the temperature as follows:

T=\frac{\Delta H_{vap}}{\Delta S_{vap}}

Thus, with the proper units, we obtain:

T=\frac{55500J/mol}{148J/(mol*K)} =375K\\\\T=102 \°C

Hence, answer is approximately 100 °C.

Best regards.

How is bacteria on mars counted as life but a heartbeat on earth not?
Sever21 [200]

Answer:

It is considered life, but that doesn’t have to do much with abortion.

We kill things all the time. Unless you are vegetarian, lots of animals are killed to give you meat. Even if you are, you’ll probably swat a mosquito that’s trying to bite you. And what about the bacteria inside your body that are constantly killed to keep you healthy?

The question is how much this life is worth. This becomes more a question of ethics, but I think we can all agree a human life is worth a lot. So killing humans is wrong. What about somewhat intelligent animals? Well, killing them just for the fun of it or because you can is wrong as well I think.Most people think that’s okay, although some people will disagree and become vegetarians.

Insect life is worth less, and killing an insect is seen by most people as okay as long as you have even a small reason for it (like being irritated by a buzzing fly).

And all the way on the bottom are bacteria. They are not conscious, even though alive.

Sorry about the first answer. I didn't look at the question carefully since I wasn't wearing my glasses.

If this doesn't help than I'm sorry.
