Explanation:

Before the advent of the wave-particle duality theory proposed by Louis de Broglie, there was a sharp distinction between mater and waves.

However, Louis de Broglie introduced the idea that mater could display wave-like properties.  Erwin Schrödinger developed this idea into what is now known as the wave mechanical model of the atom.

In this model, electrons are regarded as waves. We can only determine the probability of finding the electron within certain high probability regions within the atom called orbitals.

This idea has been the longest surviving atomic model and has greatly increased our understanding of atoms.

Answer:

A. 18

Explanation:

A neutral charged atom is an atom with 0 charge.

Anyway, first look at the periodic table and find Argon.

After you find Argon, look at its Atomic number.

Its Atomic number is 18.

And a neutral atom of Argon has 0 charge.

So we need 18 electrons for Argon to cancel out and become neutral.

Basic math:

18 +( -18) = 0

Therefore, the correct answer is A. 18

Hope it helped!

One neutrally charged atom of argon (Ar) has 18 electrons. (Option B)

Argon is an element with atomic number 18, which means it has 18 protons in its nucleus.

In a neutral atom, the number of electrons is equal to the number of protons. Therefore, a neutrally charged atom of argon will also have 18 electrons orbiting around the nucleus.

The number of electrons in an atom is determined by its atomic number and is essential for the atom's chemical properties and interactions.

Argon is commonly used as an inert gas in various applications, including welding, lighting, and as a protective gas in the manufacturing of electronics.

Answer:

132g/mol

Explanation:

The problem here is to find the molar mass of the compound in g/mol

To solve this problem, we simply sum the atomic masses of the atoms in the compound:

   (NH₄)₂ SO₄:

  Atomic mass of N  = 14g

   Atomic mass of H  = 1g

  Atomic mass of S  = 32g

  Atomic mass of O = 16g

So;

   Molar mass = 2[(14 + 4(1))] + 32 + 4(16)  = 132g/mol

Answer:  A) Bent or angular, polar

Explanation:

The central atom oxygen has two lone pairs and two bond pairs in [tex]OF_2[/tex]. The number of electron pairs are 4,  that means the hybridization will be [tex]sp^3[/tex] and the electronic geometry of the molecule will be tetrahedral. But as there are two lone pair of atoms around the central oxygen atom, repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be bent shape.

The compound [tex]OF_2[/tex] is polar as the net dipole moment of oxygen - fluoride bonds do not cancel each other out.

Answer:

T₁ = 563.19 K

Explanation:

Given data:

Initial volume = 359 mL

Final volume = 269 mL

Final temperature = 422 K

Initial temperature = ?

Solution:

The given problem will be solve through the Charles Law.

Charles Law:

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

T₁ = V₁T₂ / V₂

T₁ = 359 mL × 422 K / 269 mL

T₁ = 151498 mL.K / 269 mL

T₁ = 563.19 K

Answer:

distance divided by time so A

Explanation:

Answer:

1. 4 Km

2. 40 minutes

3. 0.1 Km/min

Explanation:

1. Determination of the total distance travelled.

From the graph given in the question above, we can see that the total distance travelled by the object is 4 Km since the path taken by the object in the graph ends at the 4 km mark.

2. Determination of the Time taken.

A careful observation of the graph given in the question shows that the entire trip took 40 minutes since the distance travelled by the object ends at the 40 minutes mark on the graph.

3. Determination of the average speed of the object.

Total distance = 4 Km

Total time = 40 mins

Average speed =..?

Average speed = Total distance / total time

Average speed = 4 / 40

Average speed = 0.1 Km/min

Answer is : It is a good thermal and electrical conductor. -The main point to be noted is that aluminium is a highly reactive element and still it is used for making cooking utensils. The reason is that aluminium has a very high affinity for oxygen. So, it reacts with oxygen and forms a layer of aluminium oxide on its surface.

Answer:

This is because aluminium reacts with oxygen present in air to form a thin layer of aluminium oxide . This oxide layer is very stable and prevents further reaction of aluminium with oxygen . Also , it is light in weight and a good conductor of heat Hence , it is used to make cooking utensils .

Volume of solution : = 3083.3 ml = 3.0833 L

Given

a 6.0% w/v

185 g of glucose

Required

Volume of solution

Solution

% w/v : the mass of solute in a volume of solution or 1 g solute in 100 ml of solution

Can be formulated :

% w/v = (mass solute(g) : volume solution(ml)) x 100

Mass of solute = mass of glucose = 185 g

The volume of solution :

= 185 g : 0.06

= 3083.3 ml

= 3.0833 L
