Methyl salicylate (oil of wintergreen) can be prepared in the lab by heating salicylic acid, C7H6O3, with methanol, CH3OH, according to the following reaction: C7H6O3 + CH3OH → C8H8O3 + H2O If the student starts with 2.53 g of salicylic acid and an excess of methanol and collects 2.62 g of methyl salicylate, what is the student’s percentage yield?

What is the most stable monatomic ion formed from nitrogen

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.

Which of the following represents the ester functional group? a. -coo- b. -cho c. -cooh d. c=o
