[cu(nh3)4]2+ solutions exhibit a deep blue-violet color. how can you use spectrophotometry to confirm that this reaction has occurred and that the product formed is tetraamminecopper (ii) sulfate?

Many ionic compounds and a few highly polar covalent compounds are because they completely ionize in water to create a solution filled with charged ions that can conduct an electric current.

What happens to the temperature of a substance when the average kinetic energy of its particles increases?

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
