<u>Answer:</u> The anion in the given formula is CH_3COO^-

<u>Explanation:</u>

Anion is the ion having negative charge. This is formed when an atom gains electrons.

The given compound is formed by the combination of lead ion and acetate ion.

Lead is the 82th element of the periodic table. The electronic confguration for this element is [Xe]4f^{14}5d^{10}6s^26p^2&#10;

This element will loose 2 electrons and thus will form Pb^{2+} ion

Acetate ion is the polyatomic ion having chemical formula of CH_3COO^- . This ion carries a charge of -1 unit.

By using criss-cross method, the oxidation state of the ions are exchanged and it forms the subscript of the other ions. This results in the formation of a neutral compound.

Hence, the anion in the given formula is CH_3COO^-

Pb(C₂H₃O₂)₂ is lead(II) acetate

Pb(C₂H₃O₂)₂ --> Pb²⁺ + C₂H₃O₂²⁻

Lead(II) acetate ionizes in aqueous solution to form lead cation and acetate anion.

The chemical formula for the anion present in the aqueous solution of Pb(C₂H₃O₂)₂ is C₂H₃O₂²⁻

C₂H₃O₂²⁻ or CH₃COO⁻ is called the acetate ion.

Therefore, the correct answer is C₂H₃O₂²⁻

How many grams of Chromium(III) nitrate are produced when Chromium reacts with 0.85 moles of Lead(IV) nitrate to produce chromiu
mina [271]

Grams of Chromium(III) nitrate produced : 268.95 g

<h3>Further explanation</h3>

Given

0.85 moles of Lead(IV) nitrate

Required

grams of Chromium(III) nitrate

Solution

Reaction

Balanced equation :

<em>2Cr₂ + 3Pb(NO₃)₄ ⇒ 4Cr(NO₃)₃ + 3Pb </em>

From the equation, mol ratio of Pb(NO₃)₄  : Cr(NO₃)₃ = 3 : 4, so mol Cr(NO₃)₃

mol Cr(NO₃)₃ =

\tt \dfrac{4}{3}\times 0.85=1.13

Mass of Chromium(III) nitrate (MW=238.0108 g/mol) :

mass = mol x MW

mass = 1.13 x 238.0108

mass = 268.95 g
