Rank the following from the lowest to highest electronegativity: O, C, F, Cl, and H. When comparing two compounds, which properties can be used to determine which one has the higher boiling point? Which of the following is an ionic compound? a. KI b. CaCl2 c. H2O d. more...
Explain how you could use the melting point to determine the purity of a solid sample.Melting pointThe physical properties like melting point and boiling points depends on the intermolecular forces and molar mass of compounds. We can some time differentiate a mixture of co...
How to Determine the Higher Boiling Point If you are comparing molecules to determine which has the higher boiling point, consider the forces that are at work within the molecule. These can be grouped into the following three factors. Factor 1: Intermolecular Forces The molecules within the liqui...
hence a tendency for crystallization. “Brick dust molecules” are drugs with very low aqueous solubility and are difficult to formulate for instance as lipid-based formulations (LBF) as they also exhibit poor lipophilic solubility. Because a...

Titration is used to determine the concentration of an unknown substance via the molar relationship expressed through the chemical reaction equation. Using these relationships, the pH value can be determined by calculating the concentration of hydrogen i
natural anisaldehyde with natural acetone produced by fermentation. Anisylidene acetone is then hydrogenated to obtain anisine acetone. Finally, the anisine acetone is demethylated to obtain natural Raspberry Ketone. The method of measuring isotope 14C is used to determine that its naturalness is over...
