Answer:

The rate of decay of atoms in container A is greater than the rate of decay of atoms in container B.

Explanation:

From the question,

Container A contains 1000 atoms

Container B contains 500 atoms

<u>The rate of decay of atoms in container A is greater than the rate of decay of atoms in container B.</u>

The reason for such is due to the difference in the concentration of the isotopes. Container A which contains higher number of atoms will have the more changes of the release of the neutron as the changes of the hitting and splitting increases as the density of the atoms increases.

<u>Thus, the atoms in the container A will therefore decay faster than the atoms in the container B. </u>

What concentration of the barium ion, ba2 , must be exceeded to precipitate baf2 from a solution that is 1. 00×10−2 m in the flu
Anon25 [30]

The amount of barium ions that must be present in order for the salt to precipitate is 0.245 M.

A solution's solubility product is the result of raising each ion's concentration to the power of its stoichiometric ratio. It is portrayed as

A combination of 1 barium ion and 2 fluoride ions results in the ionic compound known as barium fluoride.

The following equation describes the equilibrium reaction for barium fluoride ionization:

BaF₂ → Ba²⁺ + 2F⁻

Ksp = [Ba²⁺] · [F⁻]²

2.45*10^{-5}= [Ba²⁺] * [1. 00*10^{-2} ]^{2}

[Ba²⁺]=0.245 M

As a result, 0.245 M of barium ions must be present in order for the salt to precipitate.

<h3>Solubility </h3>

Solubility in chemistry refers to a chemical's capacity to dissolve in another substance, the solvent, to produce a solution. Inability of the solute to create such a solution is the opposite quality, or insolubility. A substance's degree of solubility in a given solvent is often determined by the amount of the solute present in a saturated solution, which is a solution in which no additional solute can be dissolved. The solubility equilibrium between the two compounds is considered to have been reached at this time. If there is no such restriction for a given solute and solvent, the two are referred to as being "miscible in any amounts."

What concentration of the barium ion, ba2 , must be exceeded to precipitate baf2 from a solution that is 1. 00×10−2 m in the fluoride ion, f−? ksp for barium fluoride is 2. 45×10−5

Which factor most directly affects potential energy?
Georgia [21]

Answer:

Mass, gravitational force and height

Explanation:

Potential energy of body is the energy at rest in a body and it depends on the mass, acceleration due to gravity and height of a body;

  Potential energy = mass x gravity x height  = mgh

The more the mass, gravity and height of a body, the higher the potential energy a body will posses. This is why a stone at a height has more potential energy than one on the ground.
