To determine the concentration of x in an unknown solution, 1.00 ml of 8.80 mm s was added to 5.00 ml of the unknown x solution and the mixture was diluted to 10.0 ml. after chromatographic separation, this solution gave peak areas of 5949 and 4555 for x and s, respectively. a) determine the concentration of s in the 10.0 ml solution. b) determine the concentration of x in the 10.0 ml solution. c) determine the concentration of x in the unknown solution.

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
