Explanation:

remember the equation percentage yield = actual/ theoretical yield as

4.20/4.88 x 100

86.065 so 86.1.

hope this make sense:)

The percentage yield of the product is 86.1%. The correct option is 3) 86.1%

From the question, we are to calculate the percentage yield of the product

Percentage yield can be calculated from the formula,

[tex]Percentage \ yield = \frac{Actual\ yield}{Theoretical \ yield} \times 100\%[/tex]

From the given information,

Actual yield = 4.20 g

Theoretical yield = 4.88 g

Putting the parameters into the formula, we get

[tex]Percentage \ yield = \frac{4.20}{4.88} \times 100\%[/tex]

Percentage yield = 0.86065574 × 100%

Percentage yield = 86.065574%

Percentage yield ≅ 86.1%

Hence, the percentage yield of the product is 86.1%. The correct option is 3) 86.1%

Answer:

[tex]\lambda = 9.376*10^{-8} m[/tex]

Explanation:

From the question we are told that:

 [tex]n=6level[/tex]

Generally the equation for Energy is mathematically given by

 [tex]E=\frac{hc}{\lambda}[/tex]

Since

Energy difference will be maximum when electron return to ground state

And Shortest wavelength is emitted when  there is largest energy difference

Therefore

 [tex]1/\lambda = R* (\frac{1}{nf^2} - \frac{1}{ni^2})[/tex]

Where

 [tex]R=Rydberg\ constant[/tex]

 [tex]R = 1.097*10^7[/tex]

Therefore

 [tex]1/\lambda = 1.097*10^7* ((\frac{1}{1^2} - \frac{1}{6^2})[/tex]

  [tex]\lambda = 9.376*10^{-8} m[/tex]

Answer:

Hydrogen is a very reactive element. It doesn't exist as a single atom in nature. Neither do any of the other binary nonmetals -- nitrogen, oxygen, fluorine, chlorine, bromine, and iodine. They're too prone to react with something. They react with each other and form binary molecules because the binary molecules are more stable than single atoms (by a lot!). Compounds with other atoms are even more stable, so hydrogen reacts with oxygen to form water, and chlorine reacts with sodium to form table salt.

The atomic number

Answer:

²³⁴₉₃Np.

Explanation:

We can obtain the daughter particle as follow.

Let ⁿₓM represent the daughter particle.

Thus, the equation for the reaction is given below :

²³⁴₉₂U —> ⁿₓM + ⁰₋₁e

Next, we shall determine n, x and M. This can be obtained as follow:

234 = n + 0

234 = n

n = 234

92 = x + (–1)

92 = x – 1

Volume like terms

92 + 1 = x

93 = x

x = 93

ⁿₓM => ²³⁴₉₃M => ²³⁴₉₃Np

Thus, the equation for the reaction becomes:

²³⁴₉₂U —> ²³⁴₉₃Np + ⁰₋₁e

The daughter particle => ²³⁴₉₃Np

Ghana Empire is was a kingdom in western Africa.

The Oyo Empire was the ancient African Kingdom is located in western Africa.

The Oyo Empire prospered on regional trade and became a key facilitator in moving slaves from Africa's interior to the coast and waiting European sailing ships, with its capital at Old Oyo near the River.

The human trade was so extensive that this region of Africa became known simply as the "Slave Coast."

Finally, despite all efforts, the Oyo Empire became a protectorate of the United Kingdom in 1888; its states ceased to exist as a superpower, and it never regained its prominence in the region.

During the colonial period, however, the Yoruba were one of Africa's most urbanized groups.

Thus, the ancient African kingdom of the Oyo Empire was located in western Africa.

D. Strong nuclear force, electrostatic force, weak nuclear force, gravitational force

There are four fundamental or universal forces in nature. Without these forces, all matter in the world will fall apart. The relative strength of fundamental forces is Strong nuclear force, electrostatic force, weak nuclear force, gravitational force. Thus the correct option is D.

The fundamental forces are also called the fundamental interactions. All the known forces of the nature can be collectively called the fundamental forces. The four important fundamental forces are gravitational, electrostatic, strong and weak nuclear forces.

The gravitational force is the weakest fundamental force. It is an attractive force which arises from the gravitational interaction. The attractive as well as the repulsive force caused by the electrically charged particles is defined as the electrostatic force.

The nuclear force is the strongest attractive force. The strong nuclear forces hold the nuclei of atoms together. The weak nuclear forces are responsible for the radioactive decay.

Thus the correct option is D.

Answer:

The above statement is False

Explanation:

AH is negative because the reaction gives out heat (exothermic).

AS is negative because the total entropy of the reactants is greater than that of the products (there are 4 moles of gas on reactant side compared to only 1 mole on the product side). Thus, the reactants are said to be "messier" than the products.

AG is negative at lower temperatures because at low temperatures, -TAS is more negative, resulting in the negative sign of AG.

Answer:

C. a change in the total mass of the product

Explanation:

A chemical reaction is a reaction that alters the chemical composition of the substances involved. Based on the options in this question, a chemical reaction possess the following features:

- The atoms of the substance called reactants are rearranged into products but the total number of atoms remain the same after the reaction.

- A change in odor occurs as one of the indicators that a chemical reaction has taken place.

- Energy is either absorbed (endothermic) or released (exothermic) in the chemical reaction.

However, one untrue option is that "there is a change in the total mass of the product". The total mass of a chemical reaction does not change i.e. remains the same, before or after the reaction in accordance to the law of conservation of mass.

Aluminum

Explanation:

Given

[tex]T_1 = 25.2^oC[/tex]

[tex]T_2 = 55.1^oC[/tex]

[tex]m = 5.00g[/tex]

[tex]\triangle Q= 133J[/tex]

See attachment for chart

Required

Identify the unknown substance

To do this, we simply calculate the specific heat capacity from the given parameters using:

[tex]c = \frac{\triangle Q}{m\triangle T}[/tex]

This gives:

[tex]c = \frac{\triangle Q}{m(T_2 - T_1)}[/tex]

So, we have:

[tex]c = \frac{133J}{5.00g * (55.1C - 25.2C)}[/tex]

[tex]c = \frac{133J}{5.00g * 29.9C}[/tex]

[tex]c = \frac{133J}{149.5gC}[/tex]

[tex]c = 0.89\ J/gC[/tex]

From the attached chart, we have:

[tex]Al(s) = 0.89\ J/gC[/tex] --- The specific heat capacity of Aluminum

Hence, the unknown substance is Aluminum

Explanation:

The atoms of starting substances are transformed into the ending substances because the starting substances mixed with each other and turn into new substances. The starting substances i.e. reactants vanished completely when the ending substances means products are formed completely so we can say that the vanishing of ending substance happened when the ending substances are formed.

Answer:

The correct row is B.

Explanation:

The formation of the magnesium ion, Mg²⁺, comes from the removal of 2 electrons from the valence shell of the magnesium atom. Since the remotion is of electrons, the nucleus of the atom remains the same, so the number of protons and the number of neutrons does not change.

If the number of proton change, then the atom also change, since the identity of an atom is related to the atomic number which is the same to the proton number.          

Now, if the number of neutrons changes, then we would be in the presence of an isotope of the magnesium atom.        

Therefore, the correct row is B.
