Below is an equation of A and B reacting together to create compound AB. When this equation is at equilibrium, a flask contains a combination of A2 (Green), H2 (colorless) and HI (colorless). The value of the equilibrium constant Kc for this reaction is 100 at a temperature of 200 kelvin. A2(g) + B2(g) ⇌ 2AB(g) a) If the green color of the mixture fades as the temperature is lowered, is the reaction forming AB exothermic or endothermic? b) A flask is immersed in a constant-temperature bath maintained at 200 kelvin. The flask initially contains the following: [A2] = 0.124 M, [B2] = 0.036 M and [AB] = 0.25 M. Will the concentration of AB increase or decrease as equilibrium is established? c) What is the value of Kc for the following reaction conducted at 200 kelvin? AB(g) ⇌ ½ A2(g) + ½ B2(g) d) Assume the following system is at equilibrium: A2(g) + B2(g) ⇌ 2AB(g) When this equilibrium is perturbed by a stress, the system will respond in order to establish a new position of equilibrium. Predict the specified consequence of each stress by writing "increase", "decrease" or "no change" after each sentence Stress I) When AB is removed from the vessel, the amount of A2 will II) When A2 is removed from the vessel, the amount of AB will III) When the volume of the vessel is tripple, K will
Pipelines аccоunt fоr 20% оf the totаl intercity tonnаge shipped in the U.S. However their revenues are only 4% of the total intercity transportation revenues. Why is this?
Electrоpоrаtiоn is а technique wherein cells аre shocked with a slight amount of electricity, which causes the cells to make their membranes porous. At the same time, cells are exposed to loops of the DNA made by researchers. During the brief moment that the cells are porous, they are able to scoop up and internalize the loops of DNA. Transcription and translation of the DNA can then occur in the cells. Bruno is a graduate student who wants to find out how WNT signaling impacts fin development in zebrafish embryos. It is known that Wnt gene mRNA is expressed in the developing fin, but it is unknown if it is required for fin development. Bruno knows that Dkk protein inhibits WNT signaling. Therefore, to investigate his question, Bruno carries out an experiment where he electroporates a loop of DNA containing the sequence for Dkk into a zebrafish embryonic trunk just prior to limb development, assuming that Dkk will be translated into protein in those cells and inhibit WNT signaling. Following the electroporation, Bruno observes the development of the embryos. What type of experiment was this?
