Consider the two metabolic reactions below:

reaction 1: a + b → c δg˚ = 8.8 kj/mol

reaction 2: c → d δg˚ = -15.5 kj/mol

if reaction 1 and 2 are coupled, what would the net reaction be?
choose one:
a. a + b + c → d
b. a → d
c. a + b → c + d
d. a + b → d

the net reaction would have δg˚ =

kj/mol.

30 points - when can a theory be modified if a new type of technology allows for new observations that raise new questions? a. immediately, while the questions about the theory are being asked b. after new hypotheses related to the theory are tested in experiments c. only after the new observations disprove all parts of the theory d. while scientists begin to think about how the theory could improve

The two required components for a generator

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?
