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.
The volume of air mattress is = 1.127 L
<u><em>calculation</em></u>
The volume of air is calculated using the ideal gas equation
that is Pv=nRT where,
P(pressure)= 3.5 kilopascals convert into Atm
1 atm =0.00987 KPa
?atm = 3.5 Kpa
= (3.5 kpa x 1 atm) / 0.00987 kpa =354.6 atm
V(volume) = ?
n( no of moles) = 16.5 moles
R (gas constant)= 0.0821 L.atm/mol.K
T(Temperature) = 295 K
make V the subject of the formula V=nRT/P
V= ( 16.5 moles x 0.0821 atm/mol.K x 295 k) /354.6 atm =<u><em>1.127 L</em></u>
Answer:
I think it mite be 9 maybe Ok
Answer:
the praying mantis is eating a bee to stay alive with the calories inside it's body. Therefore the praying mantis is the predator and the bee is the prey. This clearly dictates a predatory relationship.
Explanation:
the answer is self explainatory, good luck!
