You have recovered two LacZ-minus AmpR colonies from your transformation in Lab 7 and they appear as white colonies on a LBAX plate. You test each colony on a LBT plate. Only one of these two colonies grew on the LBT plate (Colony 1) while the other colony did not grow on the LBT plate (Colony 2). What is most likely the plasmid contained in Colony 2?
A: pUC119
B: pACYC184
C: pUC-tet(resistant)
D: pUC-chloramphenicol(minus)

Chlorine and water react to form hydrogen chloride and oxygen, like this: 2cl2 (g) + 2h2o (g) → 4hcl (g) + o2 (g) also, a chemist finds that at a certain temperature the equilibrium mixture of chlorine, water, hydrogen chloride, and oxygen has the following composition: compound concentration at equilibrium cl2 0.55m h2o 0.57m hcl 0.53m o2 0.34m calculate the value of the equilibrium constant kc for this reaction. round your answer to 2 significant digits.

Butane gas reacts with oxygen gas to give carbon dioxide gas and water vapor (gas). if you mix butane and oxygen in the correct stoichiometric ratio, and if the total pressure of the mixture is 390 mmhg, what is the pressure (in mmhg) of water vapor after the reaction is completed (temperature and volume do not change).

One student said that the investigation was not valid (a fair test). write a plan for the investigation that includes improvements to the method and apparatus
