What type of compound is this?

Answer:

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{9.47 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 15.730897...[/tex]

We have the final answer as

Answer:

15.7 moles of Ar

Explanation:

Given data:

Number of atoms = 9.47 ×10²⁴ atoms

Number of moles of Ar = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.  The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ atoms

9.47 ×10²⁴ atoms × 1 mole / 6.022 × 10²³ atoms

1.57×10¹ mol

15.7 mol

Answer: The spectrum would be continuous

Explanation:

Atomic transitions allow us to find that the correct answer to what would happen if there was no quantization is:

          d. the spectrum would be continous

In the models of atoms the correct explanation for the energy was given by Planck, by establishing that the energy of an electron is:  

           E = h ν

Where E is the energy, h the Planck constant and ν the frequency.

Therefore a transition occurs as the jump of an electron from one level to another  

          ΔE = E₂ - E₁

In all atomic models the levels are discrete, so the jumps are also discrete.

If the levels were continuous, the energy difference between the lines disappears and we have a continuous emission spectrum.

Let's review the different answers:

a. False. The lines disappear

b. False. This for if the separation between levels increases, which is the opposite process to the one analyzed.

c. False. The lines disappear

d) True. The spectrum is a continuum without any separation.

In conclusion, using the atomic transitions we find that the correct answer for what would happen if there was no quantization is:

     d. the spectrum would be constnuous

The options are;

A) The skater experiences acceleration both while skating in a straight line and while making her turn.

B) Because the skater does not change her direction or speed, she does not experience acceleration.

C) The skater only experiences acceleration when she is turning.

D) The skater only experiences acceleration while skating in a straight line.

Answer:

A: The skater experiences acceleration both while skating in a straight line and while making her turn

Explanation:

We are told that She speeds up on the straight portion of the rink. This means that she experienced an acceleration since the speed was not constant but gradually increasing.

Also, we are told that She slows down near each end of the rink and then turns around. This means that she reduced speed before turning and it means there was also an acceleration as well when making the turn.

Thus, she experience acceleration both in the straight line and when making turn.

Option A is correct

Ok, let us understand what is an atomic number, an atomic number is simply the proton number, the atomic number is always seen at the bottom left corner in a element of a periodic table, it is the number of proton in a atom of a certain element.

Answer:

145.97×10²³ atoms

Explanation:

Given data:

Number of moles of CO₂ = 8.08 mol

Number of atoms of CO₂ = ?

Solution:

1 mole of CO₂ contain 1 mole C atom.

8.08 mole contain 8.08× 1 = 8.08 mole of C atom.

1 mole of CO₂ contain 2 moles of O atom.

8.08mole contain 8.08×2 = 16.16 mole of O atom.

Total number of moles of atoms = 8.08 mole + 16.16 mole

Total number of moles of atoms = 24.24 mol

Number of atoms of CO₂:

1 mole of any substance contain 6.022×10²³ atoms.

24.24 mol ×6.022×10²³ atoms / 1 mol

145.97×10²³ atoms

Answer:

Explanation: A more reactive metal will displace a less reactive metal from a compound. The thermite reaction is a good example of this. It is used to produce white hot molten (liquid) iron in remote locations for welding. A lot of heat is needed to start the reaction, but then it releases an incredible amount of heat, enough to melt the iron.

aluminium + iron(III) oxide → iron + aluminium oxide

2Al + Fe2O3 → 2Fe + Al2O3

Because aluminium is more reactive than iron, it displaces iron from iron(III) oxide. The aluminium removes oxygen from the iron(III) oxide:

Answer:

Displacement reactions involve a metal and a compound of a different metal. In a displacement reaction:

Explanation:

a more reactive metal will displace a less reactive metal from its compounds

Displacement reactions are easily seen when a salt of the less reactive metal is in the solution. During the reaction:

the more reactive metal gradually disappears as it forms a solution

the less reactive metal coats the surface of the more reactive metal

For example, magnesium is more reactive than copper. When a piece of magnesium is dipped into blue copper sulfate solution:

the blue colour fades as colourless magnesium sulfate solution forms

brown copper coats the surface of the magnesium

Answer:

The correct option is A

Explanation:

Radium is an atom with the atomic number of 88. It is a metal found in group 2 of the periodic table; meaning that it has two valence electrons in it's outermost shell. As a metal that wants to form an ionic compound, radium would have to lose these two valence electrons to become a divalent positively charged cation (Ra²⁺). Thus, the correct option is A

A

Explanation:

A person would weigh more on Neptune than on planet earth because the gravitational field strength is stronger on Neptune.

A person would weight more on Neptune than on planet earth because the gravitational force in neptune is more.

Gravitational forces is a kind of attraction force which is present between two objects of masses.

Gravitational force on the neptune planet is more as compared to the gravitational force on the earth. So the mass of any object present in the neptune is more than the earth.

Hence a person would weight more on Neptune than on planet earth because gravitatinal force in neptune is more.

Balanced equation : C. CH₄ + 4Cl₂⇒  CCl₄+ 4HCl

Equalization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:  

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.  

2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product  

3. Select the coefficient of the substance with the most complex chemical formula equal to 1  

Reaction

CH₄ + Cl₂⇒  CCl₄+ HCl

aCH₄ + bCl₂⇒  CCl₄+ cHCl

C, left=a, right=1⇒a=1

H, left=4a, right=c⇒4a=c⇒4.1=c⇒c=4

Cl, left=2b, right=4+c⇒2b=4+c⇒2b=4+4⇒2b=8⇒b=4

The equation becomes :
