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:

Sally is making a model of a magnesium atom with an atomic mass number of 24 for her chemistry class. she has foam balls for the protons, neutrons, and electrons. she has added 6 neutrons to her model so far. how many more neutrons does she need to add to complete her neutral atom of magnesium?

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?

Which statement correctly describes the phosphate ion, ? it is composed of one phosphorus atom and four oxygen atoms covalently bonded together, and there is a –3 charge distributed over the entire ion. it is composed of one phosphorus atom and four oxygen atoms covalently bonded together, and there is a –3 charge on the phosphorus atom. it is composed of one phosphorus atom and four oxygen atoms ionically bonded together, and there is a –3 charge distributed over the entire ion. it is composed of one phosphorus atom and four oxygen atoms ionically bonded together, and there is a –3 charge on the phosphorus atom.
