Answer:
2. Inorganic
Explanation:
All man-made and most carbon-based compounds are inorganic
Answer:
A will float on top of B.
Explanation:
B is more dense. example A is oil and B is water.
I think that is A is the answer.
The answer for the following problem is mentioned below.
- <em><u>Therefore the final moles of the gas is 12.8 moles</u></em>
- <em><u>Therefore the option is "D" (12.8 moles)</u></em>
Explanation:
Given:
Initial moles (
) = 7.51 moles
Initial volume (
) = 8.15 L
Final volume (
) = 13.9 L
To find:
Final moles of the gas
We know;
From the ideal gas equation;
P × V = n × R × T
where;
P represents the pressure of the gas
V represents the volume of the gas
n represents the no of moles of the gas
R represents the universal gas constant
T represents the temperature of the gas
we know;
from the above mentioned equation,
V ∝ n
So,
= ![\frac{n_{1} }{n_{2} }](https://tex.z-dn.net/?f=%5Cfrac%7Bn_%7B1%7D%20%7D%7Bn_%7B2%7D%20%7D)
where,
represents the initial volume
represents the final volume
represents the initial moles
represents the final moles
So,
= ![\frac{7.51}{n_{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B7.51%7D%7Bn_%7B2%7D%20%7D)
= 12.8 moles
<em><u>Therefore the final moles of the gas is 12.8 moles</u></em>
