<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
$

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⁻

The formula of binary ionic compounds

Solution

Ionic compounds consisting of cations (ions +) and anions (ions -)

Ionic compounds usually consist of metal cations and non-metal anions

Metal: cation, positively charged.

Nonmetal: negatively charged

The anion cation's charge is crossed

The ionic compounds :

1. NaF, Na₂S, Na₃P, Na₂O

1. The two qualities used to describe winds are________ and speed. 2. a local wing that blows during the day from an ocean towar

Mazyrski [523]

<span>1. The two qualities used to describe winds are direction and speed.
2. a local wind that blows during the day from an ocean toward land is a(n) sea breeze.
3. The increase in cooling that wind can cause is called the wind-chill factor.
4. Temperature differences between the equator and poles produce convection currents.
A movement that is parallel to Earth's Surface is called wind and a local wind is that wind that blows over a short distance.</span>

How do oceanographers define salinity?

Studentka2010 [4]

The oceanographers define salinity by the number of grams of salt per kilogram of water.

Salinity is illustrated as how much salt is present in the given amount of water. It is dependent upon how much salt is found in the ocean in the specific regions. If there is a sunny environment, it may evaporate an ample amount of water, and leave behind a lot of salt, thus, the water has more salinity.

The salinity of the ocean is usually measured in Practical Salinity Unit (PSU), it is a unit based on the characteristics of seawater conductivity.
