5 0

Lead chromate is a precipitate that is formed on the reaction of lead nitrate with sodium chromate. The best method to separate this precipitate from the solution is filtration.

A precipitate can be defined as an insoluble solid formed in a chemical reaction. It appears as a cloudy and resulted after a reaction.
The lead chromate is yellow colored precipitate that forms after the reaction of lead nitrate with sodium chromate.
The process of separation of insoluble solids from the liquids by the use of filters is known as filtration. Insoluble solids are also called as precipitates these precipitates are formed in a chemical reaction.
Filtration will help in separation of insoluble solid yellow colored lead chromate precipitate from the solution using a porous material or filter that selectively inhibits the passage of solid precipitate material and allows the solution to pass through it.

How many milligrams of product can be produced from the complete Diels-Alder reaction of 180. mg of anthracene and 100. mg of ma

ZanzabumX [31]

Answer: It will be produced 276,3 mg of product

Explanation: The reaction of anthracene (C14H10) and maleic anhydride (C4H2O3) produce a compound named 9,10-dihydroanthracene-9,10-α,β-succinic anhydride (C18H12O3), as described below:

C14H10 + C4H2O3 → C18H12O3

The reaction is already balanced, which means to produce 1 mol of C18H12O3 is necessary 1 mol of anthracene and 1 mol of maleic anhydride.

1 mol of C14H10 equals 178,23 g. As it is used 180 mg of that reagent, we have 0,001 mol of anthracene. With it, the reaction produces 0,001 mol of C18H12O3.

As 1 mol of C18H12O3 equals 276,3 g, the mass produced is 276,3 mg.

Select the electron-domain geometry for a molecule with three bonding domains and one nonbonding domain.

mamaluj [8]

Answer: C) Tetrahedral

Explanation:

The number of electron pairs is 4 that means the hybridization will be $sp^3$ but as there are three bonding domains and one nonbonding domain, thus electronic geometry is tetrahedral and the molecular geometry will be trigonal pyramidal.

Linear electron geometry is possible when number of electron pairs is 2 and the hybridization will be $sp^2$ .

Trigonal planar geometry is possible when number of electron pairs is 3 and the hybridization will be $sp^3$ .

Trigonal bipyramidal geometry is possible when number of electron pairs is 5 and the hybridization will be $sp^3d$ .

Octahedral geometry is possible when number of electron pairs is 6 and the hybridization will be $sp^3d^2$ .
