Which action would shift this reaction away from solid barium sulfate and toward the dissolved ions?
ss7ja [257]

Answer:

   adding silver ions , adding chloride ions, removing chloride ions and removing silver chloride.

Explanation:

Barium sulfate is an insoluble ionic  compound since it is insoluble in water.

We can differentiate barium ions and sulfate ions away from the surface if we add a small amount of solid barium sulfate is mixed with water and shaken.

  The action would shift this reaction away from solid barium sulfate and toward the dissolved ions are adding silver ions , adding chloride ions, removing chloride ions and removing silver chloride.

An ionic and covalent quality has in every molecular bond.

In barium sulfate barium has lowest electronegativities.

Oxygen has highest electronegativities.

so the bond between both barium and sulfate is ionic in character.

Oksi-84 [34.3K]

<u>Ans: 650 J = 155 calories</u>


<u>Given:</u>

Energy in joules = 650 J

<u>To determine:</u>

The energy in calories

<u>Explanation:</u>

1 joule = 0.2388 calories

Therefore, 650 joules = 0.2388 calories * 650 J/1 J = 155 calories

What is the number of atoms per unit cell for each metal?<br> (c) Silver, Ag
katrin2010 [14]

Silver (Ag) is the number of atoms per unit cell for each metal. Silver has a face-centred cubic (FCC) unit cell structure, where there are 8 corner atoms and 6 atoms on the faces, so there are a total of 4 atoms per unit cell.

The identical unit cells are defined in such a way that they take up space without touching one another. A crystal's internal 3D arrangement of atoms, molecules, or ions is known as its lattice. It consists of a large number of unit cells. Every point of the lattice is occupied by one of the three component particles.

Primitive cubic, body-centred cubic (BCC), and face-centred cubic are the three types of unit cells (FCC). The three different sorts of unit cells will be thoroughly covered in this section.

To learn more about the unit cell refer here:
