3. how did bohr's atomic model improve on rutherford's atomic
model?
a) he discovered electrons
b) he discovered the nucleus
c) he describes specific locations for the electrons
d) they are the same model

c) he describes specific locaions for the electrons

Explanation:

he determined that electron are around the nucleus in fixed orbits where as Rutherford did not give any concept  of orbits. the concept of orbits also explains the change in energy levels as the electron moves from higher to lower or lower to higher energy level.

u i forgot the answer?

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42
