Calculate the percent yield of the aldol condensation-dehydration reaction. Melting range for the aldol condensation-dehydration product: 193.6 ºC - 197.4 ºC Calculate the percent yield of the phenylhydrazone reaction. Assume the aldehyde is the limiting reagent. Melting range for the phenylhydrazone:145.2 ºC - 151.8 ºC Calculate the percent yield of the 2,4-dinitrophenylhydrazone reaction. Assume the ketone is the limiting reagent. Melting range for the 2,4-dinitrophenylhydrazine: 155.7 ºC - 165.3 ºC

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
