You run a TLC plate spotted with three compounds naphthalene o-toulic acid and fluorenol. Predict the relative Rf values?
You'd have to know which mobile phase is used before you can make a guess at the Rf values. It might be quite hard to find a decent mobile phase to have all those compounts running, naphtalene and fluorenol are bulky and have low affinity for the polar silica, where as o-toluic acid will stick to the bottom of the plate due the COOH group.

Why might an IQ test be helpful?
An IQ test can be helpful in providing a measure of an individual's cognitive abilities, which can be used to identify strengths and weaknesses, inform educational placement, and assist with diagnosing intellectual disabilities or giftedness. It can also be used in research to investigate the relationship between intelligence and various outcomes.
Why are scientists able to predict tides in advance?
Tides are caused by the moon, so scientists can predict tides in advance from the moon's position relative to earth
How did people of central Africa predict the weather?
by observing the orientation of the crescent Moon relative to the horizon
What tools do you use to to predict future climate changes?
You could use a sling psychrometer to get the relative humidity and predict tomarrows weather. You could use satilites to see what to atmosphere looks like and predict tomarrows weather.
Why might IQ tests be helpful?
IQ tests can provide valuable information about an individual's cognitive abilities, problem-solving skills, and intellectual potential. They can help educators identify students who may benefit from specialized instruction, provide insights into cognitive strengths and weaknesses, and inform career counseling and selection processes. Additionally, IQ tests can be used to diagnose intellectual disabilities or giftedness, guide interventions, and measure changes in cognitive functioning over time.
What are the benefits of graphical representation of equations?
Graphing an equation allows you to visualize the relationship between variables and predict values of one relative to the other
How could an electron configuration be use to predict relative atomic size?
the larger the highest energy level number, the larger the atomic radius
Why do the planets orbit around the Sun in predictable ways?
We know their masses and relative velocities, so can predict their movement through calculations based on these known values.
What are sentences that has predict in it?

What is a sentence with the word predict?

How can relative humidity and dew point be used to predict the weather?
Relative humidity expresses a percentage of humidity in the air to the maximum amount of humidity that could be in the air. For example: when the temperature rises the air will be able to hold much more humidity so the relative humidity will drop.
