Answer: 22368.4 Liters
Explanation:
Initial Volume of gas V1 = 20000 liters
Initial pressure of gas P1 = 850 torr
Final volume V2 = ?
Final (standard) pressure P2 = 760 torr
Apply the formula for Boyle's law:
P1V1 = P2V2
850torr x 20000L = 760torr x V2
V2 = (850torr x 20000L)/ 760torr
V2 = (17000000)/760torr
V2 = 22368.4L
Thus, the volume of the gas at standard pressure is 22368.4 Liters
We have that for the Question, it can be said that the mass of Ammonia is
Mass_a=3.162grams
From the question we are told
<em>Ammonia </em>gas has a <u>molar</u> mass of approximately 17 <u>grams </u>per mole. At 290k and 1.2 atm, a sample of <em>ammonia </em>has a volume of 3.7 L. In <em>three </em>to five sentences, explain how you can find the mass of the <em>ammonia</em>. Then, given R= 0.0821L.atm/mol.k, calculate the mass.
Generally the equation for the is mathematically given as
Now the mass of ammonia is
Hence the mass of Ammonia is
Mass_a=3.162grams

Answer:
- First choice: <em>The hypothesis is revised and another experiment is conducted. </em>
<em></em>
Explanation:
Citing myself from brainly.com/question/12687503, a hypothesis is a reasonable explanation of a phenomenon, which tries to relate a cause with an effect, and that can be testable.
The outcome of the test can either support the hypothesis or reject it.
Both results, either supporting or rejecting the hypothesis, are good for science and help to the development of the scientific knowledge.
Hence, the fact that the data from an experiment do not support the original hypothesis is not a bad thing. The same scientist or other from the scientific community will be able to revise the hypothesis and conduct another experiment, as the first answer choice proposes.
The data are supposed to be correct, unless the analysys, not the conclusion, suggests some errors in the measures or collection of the data. So, it is not the fact that the data do not support the original hypothesis what conducts to run the experiment again (second choice is wrong, then).
The revision of the data to support the hypothesis (third choice) or adjustment of the data to match the observations (fourth hypothesis) are contrary to good practices, so they are also discarded.

Global warming and climate change can cause habitats to no longer suit animals needs and not all animals can easily adapt. Climate change can kill if severe enough
