There are many aldehydes in chocolate! analysis of the concentrations of these can enable identification of the continental origin of the cocoa beans used to produce the chocolate. african cocoa beans, for example, produce chocolate that has a higher concentration of phenacetaldehyde and benzaldehyde than other chocolates. these aldehydes add honey and almond notes to the aroma profile of chocolate. chocolate produced from caribbean cocoa beans has higher concentrations of (ee)-2,4-nonadienal and (e, e)-2,4-decadienal, which reportedly give it a "fatty, waxy" odour. madagascan cocoa beans produce chocolate that contains higher concentrations of 2-phenyl-(z)-2-butenal and 4-methyl-2-phenyl-(z)-2-pentenal. the former aldehyde is the main component of artificial chocolate flavours, while the latter is responsible for the intense bitter taste of cocoa. draw the structures of the following aldehydes [phenylacetaldehyde, benzaldehyde, and (e, e)-2,4-nonadienal.

Nconcentration refers to the molar concentration of an ion in solution. it may be identical to, or greater or less than, the molar concentration of the compound containing the ion that was used to make the solution. for soluble salts, the molarity of a particular ion is equal to the molarity of that compound times the subscript for that ion. for example, 1 m of alcl3 is 1 m in al3+ and 3 m in cl−. 1 m of (nh4)2so4 is 2 m in nh4+ and 1 m in so42−. part a what is the concentration of k+ in 0.15 m of k2s? view available hint(s) nothing m m part b if cacl2 is dissolved in water, what can be said about the concentration of the ca2+ ion? view available hint(s) if is dissolved in water, what can be said about the concentration of the ion? it has the same concentration as the cl− ion. its concentration is half that of the cl− ion. its concentration is twice that of the cl− ion. its concentration is one-third that of the cl− ion. part c a scientist wants to make a solution of tribasic sodium phosphate, na3po4, for a laboratory experiment. how many grams of na3po4 will be needed to produce 550 ml of a solution that has a concentration of na+ ions of 0.700 m ? express your answer numerically in grams. view available hint(s) mass of na3po4 n a 3 p o 4 = nothing g provide feedback
