The standard reduction potential, e’°, of any redox pair is defined for the half-cell reaction:

oxidizing agent + n electrons \rightarrow reducing agent the e’° values for the nad+/nadh and pyruvate/lactate conjugate redox pairs are -0.32 v and -0.19 v, respectively.

a) which redox pair had the greater tendency to lose electrons? explain.
b) which pair is the stronger oxidizing agent? explain.
c) beginning with 1m concentrations of each reactant and product at ph 7 and 25 °c, in which direction will the following reaction proceed?

pyruvate + nadh + h+ \rightleftharpoons lactate + nad+

d) what is the standard free energy change (? g’°) for the conversion of pyruvate to lactate?
e) what is the equilibrium constant (k’eq) for this reaction?

Galaxy whose shape seems different follow no set pattern are classified as

The image shows a group of fish. the type of social behavior shown in the image is called

98 points you will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. before you conduct your experiment, you need to form a hypothesis. a hypothesis is a prediction of what you think will happen in the experiment. the hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur. record your hypothesis here: record the results from step one of the experiment (dropping the objects in the air): first trial: second trial: third trial: record the results from step two of the experiment (dropping the objects in a vacuum): first trial: second trial: third trial: did the experiment support your hypothesis? using the data from your experiment, describe why you believe your hypothesis was either proven or disproven. what forces were acting on the objects dropped in the air? what force was acting on the objects dropped in the vacuum? part two: comparing forces choose two forces and compare and contrast these forces. you must provide two ways that they are alike and two ways that they are different. you may make a list, write in paragraph form, or make a chart. choose two forces and compare and contrast these forces. these must be different forces than used in the prior question. provide two ways that they are similar and two ways that they are different. you may make a list, write it out, or make a chart.
