If one mole of ptcl2·3nh3 reacts with agno3 to produce one mole of agcl(s), how can the formula ptcl2·3nh3 be re-written to show the proper coordination sphere?

When balancing a chemical equation:

Phosgene (carbonyl chloride), cocl2, is an extremely toxic gas that is used in manufacturing certain dyes and plastics. phosgene can be produced by reacting carbon monoxide and chlorine gas at high temperatures: co(g) cl2(g)⇌cocl2(g) carbon monoxide and chlorine gas are allowed to react in a sealed vessel at 477 ∘c . at equilibrium, the concentrations were measured and the following results obtained: gas partial pressure (atm) co 0.830 cl2 1.30 cocl2 0.220 what is the equilibrium constant, kp, of this reaction

What is the work done by the electric force to move a 1 c charge from a to b?
