What else can I help you with?
Would you expect the R value of ta pigment to be the same if a different solvent were used?
No
Would you expect RF number of a pigment to change if we altered the composition of the solvent why or why not?
No, the solubility of the pigment molecule in its organic solvent is a factor involved in the separation of pigments. More soluble molecules move faster and generally travel further. Chlorophyll B is a great example since its only soluble in fat solutions.
In which solvent do you expect a solid that ionizes well to dissolve in?
A solid that ionizes well is more likely to dissolve in a polar solvent, such as water, where the ions can interact with the solvent molecules through electrostatic interactions. This facilitates the separation of ions in the solid and their dispersal in the solution.
Would you expect any sexually mature plant to be an albino?
No, as chlorophyll reflects green light and is an essential pigment for plants.
What would you expect to find composite volcanoes on Mars?
What would you expect to find composite volcanoes on Mars? Explain why.
How would you expect Rf values to change if you went from hexane-ethyl acetate solvent system to ethyl acetate only?
If you switch from a hexane-ethyl acetate solvent system to ethyl acetate only, you would expect the Rf values to decrease. Ethyl acetate is a more polar solvent than hexane, so compounds will interact more with the solvent and have shorter distances of travel on the TLC plate, resulting in lower Rf values.
How would you expect the intrinsic volume for a polymer in a particular solvent to vary with temperature?
generally, a polymer gets dissolved in a solvent (which implies lower density and higher volume). the higher the temperature, the quicker the process, so to answer: the intrinsic volume for a polymer in a particular solvent increases with the temperature.
How should you expect your boyfriend to react after you break up with him?
Well you shouldn't expect him to take it well you should explain to him why you made the decision you made.
What can they do if you pawn a stolen gun?
Expect the police to expect YOU to explain how you came to possess a gun that had been stolen- just like any other property.
Explain what gasses would you expect to behave most ideally He Ar or HCl?
Helium
Codeine is presented in tablet mixtures and it has an Rf value of 0.6 what would you expect to be the effect of the Rf value of replacing the ammonia in the solvent by acetic acid?
Replacing ammonia with acetic acid may affect the polarity of the solvent system, potentially leading to changes in the separation and resolution of compounds in the mixture. The Rf value could be different for codeine or other components due to the altered interaction between the solvent, compounds, and the stationary phase. This change could impact the accuracy of identification or quantification of codeine in the tablet mixture.
What pigment would you NOT expect to find in a yellow autumn leaf?
In a yellow autumn leaf, you would not expect to find significant amounts of chlorophyll, the green pigment responsible for photosynthesis. As leaves change color in the fall, chlorophyll breaks down, revealing other pigments like carotenoids that produce yellow hues. Other pigments, such as anthocyanins, may be present but are typically associated with red or purple colors rather than yellow.
