The chemistry of anhydrides is similar to that of acid chlorides, although they react more slowly. A nucleophile attacks the carbonyl group to form a tetrahedral intermediate, and proton transfer to and from solvent primes the other half of the anhydride for elimination. Subsequent collapse of the tetrahedral intermediate with expulsion of the carboxylic acid yields the product ester. Draw curved arrows to show the movement of electrons in this step of the mechanism.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)

they all get energy from eating other animals, dead animals to be more precise.
