Using the potential given below, calculate the activity of cl^- in 1M KCl solution.
MissTica

Answer:

Explanation:

E° (calomel electrode) = 0.268 v

E( calomel electrode, 1M KCl) = 0.280 v

For calomel electrode

E = E^0 _( Hg^+/Hg ) - \frac{.059}{2} \times log( a_{cl^-} )^2

.280 = .268 - \frac{.059}{2} \times log( a_{cl^-} )^2

.012=  - \frac{.059}{2} \times log( a_{cl^-} )^2

log( a_{cl^-})^2= - .4067

a_{cl^-_}  = 0.626 .

Which model represents the process of nuclear fusion?
lara [203]

Nuclear fusion:

in this nuclear reaction two or more atoms of same of different elements combine to form atom of new element.

Here in the third image (as mentioned in the figure) two atoms are combining to from a new element with elimination of a small nuclear particle (like neutron or energy particle) .

Hence in image nuclear fusion is taking place.

Which are examples of artificial selection? Select all of the answers that apply?
svlad2 [7]

Answer:

The correct options are B), D) and E).  

Explanation:

Artificial selection is a process which is the intentional breeding of animals and plants based on what characters they want in the offspring.

In the above question, when a dog breeder intentionally mates two similar dogs together, when a farmer shoots the slow chickens so only faster chickens are left to mate and when a farmer selects the largest ewe and largest ram in the flock to mate, are all examples of intentional breeding.

What effect does the buoyant force have on a submerged object?
Ipatiy [6.2K]

 The buoyant force is an upward force on an object submerged in a fluid. It is the resultant of the pressure force on the surface of the object. The buoyant force may be larger than the weight of the object causing it to accelerate upwards.

Conclusion:

The weight of the water displaced by the object is subtracted from the actual weigh of the object (out of water), leaving the object with a net positive weight while submerged.

If 100. ml of a 5.0 M solution is heated on a hot plate until the volume is cut in half, what will the concentration be?
Doss [256]

Answer:

Final concentration = 10 M

Explanation:

Given data:

Initial volume = 100 mL

Initial molarity /concentration= 5 M

Final volume = 50 mL

Final molarity/concentration = ?

Solution:

Formula:

M₁V₁ = M₂V₂

M₁ = Initial molarity

V₁ = Initial volume

M₂ = Final molarity

V₂ = Final volume

Now we will put the values.

5 M × 100 mL = M₂ ×  50 mL

500 M.mL = M₂ ×  50 mL

M₂ = 500 M.mL / 50 mL

M₂ = 10 M
