I need some help on this Calculus question about polar coordinates. Consider a pasture bordering on a straight river. At 2m from the river, a goat is tied to a pole with a 4m long rope. What is the area of grass that the goat can graze? There are a couple ways to set this up, ...

Drawing polar curve
How do you draw a polar curve? For example, r=2+cos2(thetha) You need to plot points where theta varies from 0 to 2pi, unless you have a graphing program (which I do). Your example looks like 2 overlapping circles. so u mean that it can't be drawn by hand? You can draw it by ...

Benzyl alcohol is not a good sovent with which to crystallize fluorenol. The melting point looks okay so I'm assuming that polarity is the problem. Benzyl alcohol looks polar to me because it has an OH but it is only partly soluble in water. Couldn't find much on fluorenol. ...

To Sheryl: polarity
The exact question is: Benzyl alcohol (bp 205 degree C) was selected by a student to crystallize fluorenol (mp 153-154 degrees C) because the solubility characteristics of this solvent are appropriate. However, this solvent is not a good choice. Explain. So the melting point ...

Using electronegativity arguments, classify the following diatomic molecules as nonpolar (N), polar (P), or ionic (I), and enter five letters in order (e.g. NPNPI, INPNP, etc) : NaF, HF, NaH, CaO, and F2. Look up electronegativity (EN)of each element and subtract to obtain a ...

Question: Each of the solvents given should effectively separate one of following mixtures by TLC. Match the appropriate solvent with the mixture that you would expect to separate well with that solvent. Select your solvent from the following: hexane, methylene chloride, or ...

Sodium Chloride is the LEAST soluble in which of the following liquids? a. H2O b. CCl4 c. HF d. CH3OH e. CH3OOH I know NaCl is a polar molecule...and a dipole-dipole IMF bond? My guess is b because it's nonpolar and I think it's a London Dispersion IMF. Is this right? Also, ...

Please help me with this! Rank the solvents according to their polarities, from the most polar to nonpolar. ethyl acetate, water, acetone, hexane, ethanol

In my experiment I placed NaCl in glycerin for 10 minutes or more and it did not dissolve. I have looked to see if glycerin is polar or nonpolar and the information uses glycerol and glycerin interchangeably, yet they are not the same. Some information states it is polar and ...

It depends on what you are separating; polar attracts polar, and polar repels nonpolar.

What is the difference between polar and nonpolar molecules?
Sunday, June 30, 2013 at 5:37pm by Mary
polar molecule are soluble in water. how does this activity demonstrate polarity of molecule that contain the -OH group. our activity was to do an experiment mixing 2 diff liquids together to see if they dissolve and tell if its polar or nonpolar. 1. water and oil= polar 2. ...
