Below is a list of standard reduction potentials for biological half cell reactions. Using this Table answer the questions below: Succinate + CO2 + 2H+ + 2e- → alpha ketoglutarate + H2O

Eo ’ in volts -0.67

Oxaloacetate (OAA) + 2 H+ + 2e- → malate

Eo ’ in volts -0.17

Fumarate + 2 H+ + 2e- → succinate

Eo ’ in volts -0.03

(a). Under standard conditions, which metabolite would spontaneously reduce oxaloacetate (OAA)? (write the name of the metabolite)

(b). Write the possible reactions:

What is a possible quantum number set for an electron in the 3s orbital of a magnesium atom

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
