What is the simplified value of the exponent expression 16^1/4

Chemistry
1 answer:
Sliva [168]3 years ago
3 0
Answer: 2

Justitification:

1) Property: 

a^{(1/b)} =  \sqrt[b]{a}

Therefore:

16^{1/4}=  \sqrt[4]{16}

2) 16 = 2⁴

3) Property

\sqrt[n]{a^n} =a^{n/n}=a

Therefore:

\sqrt[4]{2^4} =2^{4/4}=2

The picture below shows two galaxies. 

Allisa [31]
The appropriate answer is C. Both are formed by gravitational forces. The first picture shows an elliptical galaxy. These galaxies can be round, nearly spherical or flattened disks. They contain very little dust or gas and the stars contained here are older than stars in other galaxies. The second picture shows a spiral galaxy that has a center made up of a thick mass of material and has flattened arms that rotate around the center. 

Galaxies are formed from the gravitational pull of massive objects in space. Some galaxies from around super massive black holes (spiral) or a group or collection or cluster of stars.

What is the correct coefficient for Fe2O3 in the balanced version of the following equation?
Ipatiy [6.2K]

Answer:

The coefficient of Fe₂O₃ is 1

Explanation:

__Fe₂O₃ + 3H₂ —> 2Fe + 3H₂O

To know the correct coefficient of Fe₂O₃, we shall balanced the equation. This can be obtained as follow:

Fe₂O₃ + H₂ —> Fe + H₂O

There are 2 atoms of Fe on the left side and 1 atom on right side. It can be balance by writing 2 before Fe as shown below:

Fe₂O₃ + H₂ —> 2Fe + H₂O

There are 3 atoms of O on the left side and 1 atom on the right side. It can be balance by writing 3 before H₂O as shown below:

Fe₂O₃ + H₂ —> 2Fe + 3H₂O

There are 2 atoms of H on the left side and 6 atoms on the right side. It can be balance by writing 3 before H₂ as shown below:

Fe₂O₃ + 3H₂ —> 2Fe + 3H₂O

Now, the equation is balanced.

Thus, the coefficient of Fe₂O₃ is 1

The solubility of lithium fluoride, LiF, is 1.6 g/L, or 6.2 x 10â2 M.
storchak [24]

Answer:

a. LiF(s) ⇄ Li⁺(aq) + F⁻(aq)

b. [Li⁺] = [F⁻] = 6.2 x 10⁻² M

c. Ksp = [Li⁺] [F⁻]

d. Ksp = 3.8 × 10⁻³

Explanation:

The solubility (S) of lithium fluoride, LiF, is 1.6 g/L, or 6.2 x 10⁻² M.

a. The balanced solubility equilibrium equation for LiF is:

LiF(s) ⇄ Li⁺(aq) + F⁻(aq)

b. We will make an ICE chart.

        LiF(s) ⇄ Li⁺(aq) + F⁻(aq)

I                       0           0

C                     +S         +S

E                       S           S

Then, [Li⁺] = [F⁻] = S = 6.2 x 10⁻² M

c. The solubility product constant, Ksp​, is the equilibrium constant for a solid substance dissolving in an aqueous solution.

Ksp = [Li⁺] [F⁻]

d.

Ksp = [Li⁺] [F⁻] = (6.2 x 10⁻²)² = 3.8 × 10⁻³

What type of radiation wave from the Sun does this graphic display?
liraira [26]
The answer is visible rays. For example, when a rain storm stops, the sun comes out and you are likely to see a rainbow. This is because the sun shines on water molecules in the air and the colors appear. These colors are called visible light. The only ray that a naked Human eye can see
