Separate strictly the words phase shift and reverse polarity. Scroll down to related links and look at "Phase shift". Scroll down to related links and look at "Reverse polarity".

What factors affect the solubility of an ionic compound?
Charge an ion has, temperature, polarity of solutes and solvents and pressure.
How does the polarity of a substance affect how far it travels up the chalk?
because there is polarity of molecules in there
What factors affect bond angle of a molecule?
Type of hybridizationthe number of lone pairs and bond pairs
When does a shape of a molecule affect its polarity?
when the molecule contains polar bond
What are the usp limits for the theoretical plates in gas chromatography?
There is no "limit" set by the USP, it depends on the molecules and what is reasonable. For example in HPLC, 2000 plates is typically what you would like to shoot for but if its a compound with low sensitivity and you need to see low levels you might inject more compound which would increase sensitivity but also probably affect peak shape and thus theoretical plates. The answer is it depends
Does the nature of light effect the polarity of compound?
No, the polarity of a compound may however affect light.
Does polarity of a solvent mixture affect the completeness of the separation in chromatography?
you just talk to spongebob and it will make sense. He's spongey.
What factors affect the solubility of an ionic compound?
Charge an ion has, temperature, polarity of solutes and solvents and pressure.
How does the polarity of a substance affect how far it travels up the chalk?
because there is polarity of molecules in there
How does polarity affect electrons?
By switching from one pH range to another, the compound changes its polarity and its preference for residing in either a polar or non-polar solvent.
How can you tell if bumps on the oscilloscope trace are due to the stimulus artifact or are part of a compound action potential?
The stimulus artifact is biphasic and roughly symmetrical. If you reverse the polarity of the stimulus you will see no or little change in the stimulus artifact but should see a decrease or absence of the neural response. The rate of change in a stimulus artifact is generally an order of magnitude faster than most neural responses so that filtering will disproportionally affect it. Always set your stimulus to lowest strength needed to elicit a response before reversing polarity. If you are on the wrong polarity this has the risk of killing your preparation.
What are factors affect the solubility of a substance?
Temperature and polarity.
What factors affect bond angle of a molecule?
Type of hybridizationthe number of lone pairs and bond pairs
Does boiling point affect the polarity of water?
No, boiling does not affect the polarity of water. What it does is create enough energy for the water molecules to separate from one another. But the water molecules are still polar.
What two factors determine the rate at which the pigments travel up the chromatography paper?
Rf value. polarity of solvent
Which of the following factors does not affect membrane permeability?
The polarity of membrane phospholipids -Mastering Biology
When does a shape of a molecule affect its polarity?
when the molecule contains polar bond
