Answer:

a. Na₂[Zn(OH)₄]

b. [Co(Cl)₂(en)₂]NO₃

c. [Pt(H₂O)₃Br]Cl

d. [Pt(NH₃)₃(NO₂)₂]Br₂

Explanation:

(a) Sodium tetrahydroxozincate(II)

Zincate(II) indicates the metal is Zn²⁺, tetrahydroxo are 4OH⁻, that is

[Zn(OH)₄]²⁻. As the molecule is a neutral salt of sodium:

<em>Na₂[Zn(OH)₄]</em>

(b) Dichlorobis(ethylenediamine)cobalt(III) nitrate

The metal is Co³⁺, bis(ethylenediamine) are (en)₂ and dichloro are 2 Cl⁻, that is:

[CoCl₂(en)]⁺

The counterion is NO₃⁻, that is:

<em>[CoCl₂(en)₂]NO₃</em>

(c) Triaquabromoplatinum(II) chloride

The metal is Pt²⁺, ligands are 3 H₂O and 1 Br⁻, that is:

[Pt(H₂O)₃Br]⁺

The counterion is Cl⁻:

<em>[Pt(H₂O)₃Br]Cl</em>

(d) Tetra-amminedinitroplatinum(IV) bromide

The metal is Pt⁴⁺, ligands are 2 NO₂⁻ anf 3 NH₃, that is:

[Pt(NH₃)₃(NO₂)₂]²⁺

As counterion is Br⁻ you need 2 Br⁻ for the neutral salt, that is:

<em>[Pt(NH₃)₃(NO₂)₂]Br₂</em>

<em></em>

I hope it helps!

koban [17]

Answer:

See explanation

Explanation:

A limiting reactant is the reactant in a reaction that is done reacting first, because there are less moles of it than are needed for a full reaction with the other compound or compounds.

Hope this helps!

Paladinen [302]
  • The change in color from blue to pink of the cobalt complexes here has been the basis of cobalt chloride indicator papers for the detection of the presence of water. It is also used in self-indicating silica gel desiccant granules.
  • Pink cobalt species + chloride ions ⇌ Blue cobalt species + water molecules

<u>Explanation</u>:

  • The adjustment in color from blue to the pink of the cobalt complexes here has been the premise of cobalt chloride indicator papers for the detection of the presence of water. It is likewise utilized in self-demonstrating silica gel desiccant granules.  

Pink cobalt species + chloride particles ⇌ Blue cobalt species + water molecules  

  • The response of [Co(H2O)6]2+(aq) + 4Cl–(aq) → [CoCl4]2–(aq) + 6H2O(l) is endothermic. In this manner, as per Le Chatelier's rule, when the temperature is raised, the situation of the balance will move to one side, shaping a greater amount of the blue complex particle at the expense of the pink species.  
  • Including concentrated hydrochloric raises the chloride particle fixation, making the equilibrium move to one side, as per Le Chatelier. Including water brings down the chloride particle fixation, moving the equilibrium the other way.
  • As an extension, it is conceivable to show that it is the Cl–particles in the hydrochloric acid that move the balance by including a spatula of sodium chloride rather than the pink arrangement. This delivers a bluer color, however, this may take some time because the salt is delayed to dissolve.
