Oleic acid has one double bond and a molar mass of 282.45 g/mol. If iodine number is equal to the number of grams of Iodine (1) that combines with 100 grams of a fat or oil substance; calculte the iodine number for Oleic acid.
A solution that is made by combining 125mL of 0.050 M hydrofluoric acid with 50.0mL of 0.10 M sodium fluoride.
The difference between these forces is why some solids dissolve by an exothermic reaction (release heat), while other solids absorb heat and cool the solution. For an ionic solid dissolving in water, briefly identify the attractive
