The aldol reaction is catalyzed by acid as well as by base. Write a detailed mechanism for the acid-catalyzed condensation of acetaldehyde (equation below), and use it to respond. Draw the intermediate ion on the pathway from ethanal (acetaldeyhde) to the reactive nucleophile.

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.      

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8

the correct answer would be b) volume versus temperature, because they are also directly proportional.
