Which statements about the operation of an automated micropipettor are true? The volume dial has already been set, do not alter

it. The volume dial has not been set, adjust it to the desired setting. A new disposable plastic tip is required for each sample. The point of initial resistance is the level of depression that will fill the pipette with the desired volume of solution.

Answer:

The correct statement is that the point of initial resistance is the level of depression that will fill the pipette with the desired volume of solution.

Explanation:

The pipette can be otherwise stored vertically or horizontally, this has nothing to do with the operation, and before the operation, the dial needs to be set. Also, the plastic pipette tip should not be ejected at all, thus, no new disposable plastic tip is required for each sample.

The correct statement is that the point of initial resistance is the level of depression that will fill the pipette with the desired volume of solution.

suppose you are testing the buoyancy of different objects . study the table and choose object with the greatest buoyant force
Alika [10]
The formula to calculate buoyant force (FB) states that the upward force exerted on an immersed object is equal to the density (ρ ) of the fluid multiplied by both the fluid’s displaced volume (V) and the gravitational acceleration (g), or
FB = ρ x V x g.<span> 
I hope that helped with what you're doing.

All organic compound soluble in WATEe and conduct electrically ​
Delvig [45]

No

Explanation:

Not all organic substances are soluble in water and will not conduct electricity. Only polar organic compounds are soluble in water and will conduct electricity.

  • The general rule of solubility is that like dissolves likes.
  • Polar compounds will only dissolve other polar compounds too. Water is a polar solvent.
  • Non-polar compounds will only dissolve in non-polar compounds too.
  • Since water is a polar organic compound, only polar organic compounds will dissolve in it.
  • Not all organic compounds are polar.
  • When a compound dissolves in water, it produces ions that makes it able to conduct electricity.
  • Fats and oil are insoluble in water

Which of the following is equal to 3.3mm3? A) 3.3 x 10^-6 m^3 B) 3.3 x 10^-9 m^3 C) 3.3 x 10^-6 cm^3 D) 3.3 x 10^-9 cm^3
vazorg [7]
Step 1 - Since 3.3mm^3 = 0.0033cm^3, convert that to 3.3x10^-3 cm^3.

Step 2 - Since 1cm^3 = 1x10^-6 m^3, times 3.3 by that. (3.3 x 1 x 10^-6) = 0.0000033

Step 3 - 0.0000033 = 3.3 x 10 ^-6 m^3, which is your answer choice A.
