calculate the oxidation number of metals in the following co-ordination compounds. 1) [cr(nh3)(no3)3] 2) [ni(nh3)6]cl2 3) k3[al(c2o4)3]

elements make up everything, and they combine to make compounds.

the answer is c

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

i hope this !
