If three jars of the same amount of hexachlorobenzene, ethanol, and benzyl alcohol are left open in a room, which of them would have the highest air concentration after the same period? Why? You can ignore degradation process in this question. Hint: a higher vapor pressure would mean the chemical has a higher tendency to evaporate. 2. Which of these chemicals are considered persistent organic pollutants by the Stockholm Convention (Links to an external site.)Links to an external site.? Name...

A newly discovered chemical compound has just been found. To analyze the properties of this chemical compound a set of proteins were treated with the compound. After treatment the proteins were denatured and only the primary structure remained. The chemical properties of the compound suggest that the compound does not disrupt non-covalent interactions. Given this information what bonds were likely disrupted to cause the proteins to revert back to the primary structure? Based on the information given in question 2, do...

1. what are some of the properties which make water a good environment for chemical reactions ? 2. What is an acid? Base? What is considered acidic or basic or neutral? Which substance/ compound is neutral? Know the pH scale—what does it tell us, what is it based on (its relation to H+ ion concentration)? It ranges from 0 to 14. Know which points/numbers on the scale are acidic, which are basic, which is neutral. What is the difference in...

Section Name Experiment 2 Advance Study Assignment: Properties of Systems in Chemical Equilibrium 1. Methyl orange, HMO, is a common acid-base indicator. In solution it ionizes according to the equation: HMO(aq) H(aq) + MO (aq) red yellow If methyl orange is added to distilled water, the solution turns yellow. If a drop or two of 6 M HCl is added to the yellow solution, it turns red. If to that solution one adds a few drops of 6 M NaOH...

2. List some familiar adaptations animals have to reduce the effects of temperature extremes on their many vital, enzyme-catalyzed reactions. 3. In general, the rates of chemical reactions double for every 10 degrees (Celsius) increase in temperature. What changes at the molecular level account for slower reaction rates of enzyme- catalyzed reactions at high temperatures? (Hint: enzymes are protein molecules. What happens to protein molecules when they are heated?) Why are enzyme catalyzed reactions also slower at low temperatures? (Hint:...

New Jersey state lawmakers last year passed a bill that would
have required the Drinking Water Institute to formulate a state
regulation, known as a maximum contaminant level (MCL), for TCP.
Governor Chris Christie refused to sign the bill. The discovery of
the chemical 1,2,3- trichloropropane (TCP) in two public water
wells has recently renewed concerns from residents in the
Burlington County, NJ community.
