Answer:
a). P = 688 atm
b). P = 1083.04 atm
c).Δ G = 16.188 J/mol
Explanation:
a). Fugacity 'f' can be calculated from the following equations :
where, P = pressure , Z = compressibility
Now, the virial equation is :
........(1)
Also, PV=ZRT for real gases .......(2)
∴ 
So from the fugacity equation ,
Putting the value of P = 500 atm in the above equation, we get,
f = 688 atm
b). Given f = 2P
∴ P = 1083.04 atm
c). dG = Vdp -S dt at constant temperature, dT = 0
Therefore, dG = V dp

To most geologists, the term "acid test" means placing a drop of dilute (5% to 10%) hydrochloric acid on a rock or mineral and watching for bubbles of carbon<span> dioxide gas to be released. The bubbles signal the presence of carbonate minerals such as</span>calcite<span>, </span>dolomite<span>, or one of the minerals listed in Table 1.</span>
Answer:
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. ... Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions.
Explanation:
does that make any sense???
The answer is C.
This can be concluded by looking at the other answers and eliminating them one-by-one.
Managing (Or conserving) a natural resource means to sustain it and use it as efficiently as possible.
With this in mind, we can look and eliminate certain answers.
A is incorrect because driving a car uses gas, a natural resource. By using as much gas as possible, the resource would be wasted instead of conserved.
B is incorrect because water is a natural resource. Once again, by using this, it's wasted where it could be conserved.
C is correct because planting trees would conserve the resource; by consistently planting trees where they're cut, the chances of running out of wood decrease.
D is incorrect because both the water and the creatures that live inside it are natural resources. By dumping toxic waste, these resources are wasted where it could be conserved.
Hope this helped you! :)
