Answer:
Mercury is the most dense whereas Titanium is the least dense.
Explanation:
Since Density = Mass / Volume, the slope of the line can immediately tell us its relative density between the metals.
Answer: where a lever rests or is supported and where it pivots
Explanation:
Answer:
Because as the concentration is diminished, the capacity to transfer electricity is diminished as well.
Explanation:
Hello!
In this case, since electrolytes are substances that are able to conduct the electricity in aqueous media (solutions in which water is the the solvent) because they have the capacity to form ions with both positive and negative charges, due to the fact that HCl is a strong acid, we notice it is fully ionized in solution and therefore it is a strong electrolyte. However, when the concentration is diminished, we can notice that strength is diminished as well because less ions will have the capacity to transfer the electricity and therefore it'd become a poor conductor or weak electrolyte.
Best regards!
Answer:
Explanation:
From the information given:
Feed F = 150.0 kmol/hr
The saturated liquid mixture of the distillation column is
= 30%
Reflux ration = 2.0%
methanol distillate mole fraction
= 0.990
recovery of methanol in the distillate = 97.0%
The distillate flow rate D can be determined by using the formula;

D = 0.97 × 150 × 0.3
D = 43.65 kmol/h
The bottom flow rate Balance B on the column is:
F = D + B
150 = 43.65 + B
B = ( 150 - 43.65 )kmol/h
B = 106.35 kmol/h
The methanol mole fraction in the bottom
can be computed by using the formula:

150(0.3) = 43.65(0.999) + 106.3(
)
45 = 43.60635 + 106.3(
)
45 - 43.60635 = 106.3(
)
1.39365 = 106.3(
)
= 1.39365 / 106.3
= 0.013
the fractional recovery of water in the bottoms f is calculated as:



f = 0.99969
