Astudent is given five samples and told they are lysine (an amino acid), lactose (a disaccharide), insulin (a protein hormone), rna and fat. the samples are in test tubes marked 1-5, but the student doesn’t know which compound is in which tube. the student is instructed to identify the contents of each tube. in her first test, she tries to hydrolyze a portion of the contents of each tube. hydrolysis occurs in all tubes except tube 5. in the next test, she finds that tubes 3, 4, and 5 are positive for nitrogen but only tube 3 gives a positive result for the presence of sulfur. in the next test the student shows that the compound in tube 4 contains a high percentage of phosphate. in the final test the student shows that compound 1 is hydrophobic. base on these data, identify what is in each tube.

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
