Lead (II) acetate trihydrate is the systematic name for the formula Pb(C₂H₃O₂)₂ . 3H₂O.

<h3>What is Molecular Formula ?</h3>

The chemical formula that gives total number of atoms of each element in one molecule of a compound is called Molecular Formula.

<h3>What is Oxidation State ?</h3>

Oxidation state is also known as oxidation number. It is defined as the atom is equal to the total number of electrons which have been removed from the element in order to form chemical bond with other atom.

Now find the oxidation state of Pb in Pb(C₂H₃O₂)₂ .3H₂O

Assume the oxidation state of Pb in Pb(C₂H₃O₂)₂ .3H₂O be x

x + 2 × (-1) + 3 × 0 = 0

x - 2 + 0 = 0

x = 2

Oxidation state of Pb is +2 or (II)

Thus from the above conclusion we can say that The systematic name for the formula Pb(C₂H₃O₂)₂ .3H₂O is Lead (II) acetate trihydrate.

The following are products in the chemical reaction shown below.
scoundrel [369]

Answer:

C₆H₁₂O₆ and O₂

Explanation:

To know which option is correct, it important that we know the concepts of chemical equation .

A chemical equation gives us an expression of a chemical reaction in terms of symbols and formula. There are two sides to every equation. The side bearing the reactant and the side bearing the product.

The reactant is located on the left side and the product is located on the right side.

Reactant —> Product

With the above information, let us answer the question given above.

6CO₂ + 6H₂O —> C₆H₁₂O₆ + 6O₂

The products are located on the right side of the equation.

Thus, the products of the reaction is C₆H₁₂O₆ and O₂
