The solubility of benzoic acid in water is 0.05 g/100 ml at 0oC and 7.87 g/100 ml at 100oC. Answer the following questions if 5.69 grams of benzoic acid were to be heated to boiling in 100 ml of water. What would be the maximum possible percent recovery in a second batch, if the mother liquor was reduced to 44.09 ml, chilled in ice water and vacuumed filtered? Put your answer in 3 significant figures.

The solubility of benzoic acid in water is 6.80 g per 100 mL at 100 °C and 0.34 g per 100 mL at 25 °C. Calculate the minimum volume of water needed to dissolve 1.00 g of benzoic acid at 100 °C. Calculate the maximum theoretical percent recovery from recrystallization of 1.00 g of benzoic acid from 15 mL of water, assuming the solution is filtered at 25 °C. How much benzoic acid can you dissolve in 25 mL of...

C The boiling point of H,O is much higher than the boiling point of HS. H2O is a molecular compound, while HS is an ionic compound. H2O is a polar molecule, so the attractions between the molecules are stronger than those between nonpolar H2S molecules. H2O has strong hydrogen bonds between its molecules, and HS molecules cannot form hydrogen bonds. The dispersion forces between the H2O molecules are much stronger. d The boiling point of CH,O is much higher than...

Daisy Dominguez Solubility of Benzoic Acid in Water y = 1.479e9.0133 R-0.9955 20 40 A graph of temperature (°C) versus solubility of benzoic acid in water (g/L) has a good exponential fit, y = 1.479e0.0357x, indicated by the Goodness of Fit R? = 0.9955. Given that you used 19.9 ml of water to dissolve 0.786 g of benzoic acid, what was the actual temperature of your recrystallization setup according to this exponential equation? Don't forget that there are 1000 ml...
The boiling point of iodine (12) is much higher than the boiling point of helium (He)....
The boiling point of iodine (12) is much higher than the boiling point of helium (He). Why? O 12 has a larger electron cloud than He, so more energy is required to overcome the stronger London Dispersion Forces. O It requires more energy to break the covalent bonds in 12 than to overcome the London Dispersion Forces between He atoms. The bonds between iodine atoms are stronger than the bonds between helium atoms and therefore harder to break. O 12...
