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.

Four objects each with charge +2.0×10−7c are located at the corners of a square whose sides are 2.0 m long. part a what quantities can be determined using this information? check all that apply. the electric force on a charged object placed at the center of the square. the mass of each object. the total electric potential energy of the system consisting of the four charged objects. part b find the electric force on a charged object placed at the center of the square.
