Answer:
The answer is "Choice b,c, and d".
Explanation:
The distillation would be the separation phase of working liquids that boil close to each other. Whenever the formulation is long-term, a much more fraction of a compound collected will have a lower boiling point than it would otherwise be. In other phrases, it'll be pulverized with both the lower level, also with the boiling point. Its structure of both the diluted volatile component may therefore include another cell's contaminants.
Answer:
The FEM is a general numerical method for solving partial differential equations in two or three space variables (i.e., some boundary value problems). To solve a problem, the FEM subdivides a large system into smaller, simpler parts that are called finite elements.
Answer:
A) 
B)
Explanation:
Given data:
P-1 = 100 lbf/in^2
degree f


effeciency = 80%
from steady flow enerfy equation

where h1 and h2 are inlet and exit enthalpy
for P1 = 100 lbf/in^2 and T1 = 500 degree F


for P1 = 40 lbf/in^2


exit enthalapy h_2


from above equation
[1 Btu/lbm = 25037 ft^2/s^2]

b) amount of entropy


at ![h_2 = 1197.77 Btu/lbm [\tex] and [tex]P_2 = 40 lbf/in^2](https://tex.z-dn.net/?f=h_2%20%3D%201197.77%20Btu%2Flbm%20%5B%5Ctex%5D%20%20and%20%5Btex%5DP_2%20%3D%2040%20lbf%2Fin%5E2)


Answer:
The element that is oxidized is carbon.
Its oxidation state increased. It increased from -4 to +4
Explanation:
Oxidation is a process that involves increase in oxidation number.
The oxidation number of carbon in CH4 is -4
C + (1×4) = 0
C + 4 = 0
C = 0 - 4 = -4
The oxidation number of carbon in CO2 is +4
C + (2×-2) = 0
C - 4 = 0
C = 0+4 = 4
Increase in the oxidation number of carbon from -4 to +4 means carbon is oxidized
