Silicate [SiO4] 4- and Phosphate [PO4]3- anions seem to be quite similar when briefly viewed. However, there are subtle differences that differintiate these two molecules. What is the electrostatic valency (or e.v. for short) bond strengths for the phosphate and silicate anions mentioned above? Given the electrosatic valency principal, what is the difference between these molecules relative to the structures for silicate and phosphate minerals? Lastly, I want you to calculate the value of e.v. for both molecules (phosphate and silicate). Remember, this is a three part question.

Impure nickel, refined by smelting sulfide ores in a blast furnace, can be convertedinto metal from 99.90% to 99.99% purity by the Mond process. The primaryreaction involved in the Mond process is:Ni(s) + 4CO(g) ⇌ Ni(CO)4(g)In the second step of the Mond process, the gaseous Ni(CO)4 is isolated andheated to 227°C. The purpose of this step is to deposit as much nickel as possibleas pure solid (the reverse of the preceding reaction). Calculate the equilibriumconstant for the preceding reaction at 227°C.
