A solution containing 3.51 mM X (analyte) and 1.67 mM S (internal standard) gave peak areas of 3505 and 10437, respectively, in a chromatographic analysis. Then 1.00 mL of 8.47 mM S was added to 5.00 mL of unknown X, and the mixture was diluted to 10.0 mL. This solution gave peak areas of 5428 and 4431 for X and S, respectively. Answer the following questions and enter your results with numerical values only. Calculate the response factor for the analyte. (keep four significant figures) Find the concentration (mM) of X in the 16.0 mL of mixed solution. Find the concentration (mM) of X in the original unknown.

Indicate whether each statement is true or false. (a) Thesequence of amino acids in a protein, from the amine endto the acid end, is called the primary structure of the protein.(b) Alpha helix and beta sheet structures are examplesof quaternary protein structure. (c) It is impossiblefor more than one protein to bind to another and make ahigher order structure.
For each chemical reaction listed in the first column of the table below, predict the sign (positive or negative) of the reaction entropy AS If it's not possible to decide with the information given, check the "not enough information" rxn' button in the last column. Note for advanced students: Assume the temperature remains constant. Assume all gases and solutions are ideal. reaction 4Fe(s) + 30₂ (g) 2 Fe₂O3 (s) Ag Cl (s) → Ag+ (aq) + Cl¯(aq) 2NH3(g) N₂(g) + 3H₂(g) sign of reaction entropy AS rxn AS > 0 rxn not enough information. 0 rxn not enough information.
