Which image shows an ion? A image 1 only
B image 2 only
C. image 1 and 2
D neither image
Select an answer

D

Explanation:

Both images have 4 protons (positive particles) and 4 electrons (negative particles) so in total they don't have a charge. (you don't have to worry about neutrons in this case, because they don't have a charge.)

An ion has a charge so neither image is an ion

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
