Make 4 lists-physical properties, chemical properties, physical changes and chemical changes. Then put words from the scenario in the proper list.
Scenario:
Sodium is a silvery-white, highly reactive metal. Chlorine is a yellow-green gas. When they are mixed together they react with one another to form chemical compound called Sodium chloride (salt). The reaction is exothermic, producing a bright yellow light and giving off heat.
Salt is soluble in water. Salt will give water a greater density and decrease the boiling point of water.

Apeak with a retention time of 407 s has a width at half-height (w1/2) of 7.6 s. a neighboring peak is eluted 17 s later with a w1/2 of 9.4 s. a compound that is known not to be retained was eluted in 2.5 s. the peaks are not baseline resolved. how many theoretical plates would be needed to achieve a resolution of 1.5?
