Which two elements would NOT be capable of forming an ionic bond?

Nacl

Explanation:

Phosphorus and chlorine are the two groups of elements that would not be capable of forming an ionic bond. Ionic bonds occurs between a metal and a non-metal to produce an electrovalent compound.

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

24

i think its 100.

hope this !
