-2.7 × 10^2 is the result of the equation.
Answer:
Instrumental methods
surface analysis
high performance liquid chromatography
atomic spectroscopy
potentiometry
Classical methods
precipitation titration
gravimetric analysis
Explanation:
Instrumental methods of analysis are those analytical methods in which the responsibility of detection has been removed from human beings and placed on automated instruments while classical methods are those analytical methods in which the responsibility of detection remains the responsibility of human beings.
Many instrumental methods such as HPLC rely on computer screens as readout devices.
Answer:
The cohesive forces of mercury are much stronger than its adhesive forces.
Explanation:
Cohesive forces are forces that exist between the particles that compose a substance while adhesive forces refer to forces that exist between the particles of a substance and those of another substance.
The cohesive forces in mercury far outweigh the adhesive forces between the mercury drops and glass. Hence when mercury is put into a capillary tube, its meniscus is convex because cohesive forces tend to draw the liquid mercury into a drop.
Hence, the surface tension in mercury makes the mercury in the capillary tube to fall below the height of the mercury in the dish.
