The only information in this problem that we are given with are the stoichiometric coefficients in the reaction, and the rate of disappearance of NH₃ as 0.05 M/s. The rate of disappearance always has a negative sign. The general formula would be:
Rate of Reaction = -(ΔNH₃/Δtime)(1/v), where v is the stoichiometric coefficient of NH₃ in the reaction
Substituting the values,
Rate of Reaction = -(0.05 M/s)(1/4) = <em>-0.0125 M/s</em>
<span>[Cu(NH3)4]2+ forms a blue solution. When concentrated HCl is added to this solution, what color will the solution change to yellow.
Reason:
When conc. HCl is added to the solution containing </span>[Cu(NH3)4]2+, Cl- ions will replace NH3 and form [Cu(Cl)4]2- complex. This can be understood for the following reaction:
[Cu(NH3)4]2+ + Cl- ↔ [Cu(Cl)4]2- + NH3
The Cl- ion is a weak field ligand, while NH3 is a strong field ligand. Hence, Cl- will in less splitting of d-orbitals, as compared to NH3. Due to this, photons of different energies will be absorbed by these complexes, and hence they display different colours.

Explanation:
The presence of chloride ions in water can be established by adding dilute trioxonitrate V acid to a sample of the water in drops followed by aqueous silver trioxonitrate V.
If a white precipitate is formed, which is soluble in excess aqueous ammonia solution, then the presence of chloride ion in the water sample is ultimately confirmed.
Rules for naming ionic compounds with transition metal requires the elementary name of metal followed the anion name with suffix ide.
<h3>What are ionic compounds?</h3>
Ionic compounds are made up of ions, which are charged particles that occur when an atom (or group of atoms) acquires or loses electrons. Generally cations are metals and anions are non metals in it.
Following rules will be considered during naming:
- First determine the metal's elemental name.
- Give the nonmetal its elemental name and the suffix -ide.
- Use roman numerals to denote positive charge when naming metals that can have distinct oxidation states.
- Name the polyatomic ions according to their names.
Hence rules for naming are listed above.

The answer is "Location E, because Earth's axis is tilted towards the sun" :D
