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.
stop cheating and putting your classmates at a disadvantage. wikipedia it - it's a simple equation!
i am doing this in 9th grade physics right now. i have a test tomorrow too. but i cannot answer this. i guess i need to get studying, BYEE

Highest melting point. (Note that this does not assure that the remaining compounds are not also ionic.)
I predict that an ion of sodium will have a charge of plus one.

Small, NONpolar compounds
Tides are caused by the moon, so scientists can predict tides in advance from the moon's position relative to earth
by observing the orientation of the crescent Moon relative to the horizon
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.
Only after experiments and determination of the chemical composition.
This is a solubilty chart; see an example at this link.

Electronegativity can help, but experience and factual knowledge of each case is needed for most compounds.
If a material contain two or more compounds is a mixture.Of course sometimes an analytical determination is necessary.
Graphing an equation allows you to visualize the relationship between variables and predict values of one relative to the other
the larger the highest energy level number, the larger the atomic radius
