Answer:
Cryogenic distillation
Explanation:
Cryogenic Distillation is the process in which Nitrogen and Oxygen are separated from air. Thus in cryogenic distillations the components having very low boiling points are distilled selectively at low temperatures. This method produces products of high purity but also it is quite energy intensive.
Answer:
8.
Explanation:
Atomic number tells us the number of protons in an element. Mass number is the total amount of mass in an atom, and it comes from the sum of the mass of protons and neutrons, which are both considered to have a mass of 1 amu.
If the total mass is 16amu and 8amu comes from the 8 protons, the remaining mass comes from neutrons.
16 - 8 = 8
Answer:
The detailed calculation is shown in the attached file.
last condition (1000 K in 150.000 dm3) will have the least deviations and it is the condition where real gas will behave as ideal gases
Explanation:
Real gas behave more ideally or they tend towards ideality when there is the least deviation, or their inter-molecular forces between their molecules are mainly responsible for their deviations as such gases with the strongest intermolecular forces shows the strongest deviations. As such, when their is an increase in temperature and volume and a decrease in pressure, real gas tends towards ideal gas in this case.
From the three conditions given, it is obvious that the last condition(1000 K in 150.000 dm3) will have the least deviations.
Answer:
c = 0.528 J/g.°C
Explanation:
Given data:
Mass of titanium = 43.56 g
Heat absorbed = 0.476 KJ = 476 j
Initial temperature = 20.5°C
Final temperature = 41.2°C
Specific heat capacity = ?
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 41.2°C - 20.5°C
ΔT = 20.7 °C
476 J = 43.56 g × c × 20.7 °C
476 J = 901.692 g.°C × c
c = 476 J / 901.692 g.°C
c = 0.528 J/g.°C
