a. when two objects collide they will keep their initial speeds
b. when two objects collide the systems momentum remains the same
c. when two objects collide they will keep their initial momenta
d. when two objects collide the systems momenta changes

The answer is

B. when two objects collide the systems momentum remains the same

i just did test

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

2.4
