Answer:
C-term
Explanation:
A correlation between plate height and mobile phase velocity is known as the van Deemter equation.
Where;
H is the plate height
A is the eddy diffusion term
B is the longitudinal diffusion term
C is the resistance to mass transfer coefficient
u is the linear velocity
Here C-term describes the mass transfer of sample components between the stationary phase and the mobile phase during separation. One of the major factor affecting C-term is the particle size, changing the diameter equally changes the particle size.
The answer is C-term
Answer:
Q=msΔT
rearranging in terms of temperature gives:
ΔT=Q/ms
=1320j/(230g×0.338(j/g°C))
=16.97967584°C
=> ΔT=17.0°C
Answer:
The right choice is "wind power requires a lot of space and depends on local weather patterns "
Explanation:
- solar power produces harmful chemicals
- it is incorrect because solar power doesn't produce any chemicals
2. geothermal power requires more land than other power plants
-
it is incorrect because geothermal power requires digging a stable 5 km-deep shaft not a land
3. nuclear power produces small amounts of energy from large masses
- it is incorrect because nuclear power produces large amounts of energy from small masses.
So the right choice is "wind power requires a lot of space and depends on local weather patterns "
