Particle A is present in 3d orbitals and Particle B is packed in the nucleus.

Explanation:

Based on the quantum model, the correct location of the subatomic particles is particle A is present in 3d orbitals and Particle B is packed in the nucleus.

Negatively charged particles in an atom are called electrons.
Positvely charged particles are called protons.
Particle A is electron.
Particle B is protons.

According to the quantum model of an atom, electrons moves in specific energy levels round the atom.

An orbital is the place in an atom with the maximum probability of find electrons. The 3d orbital is one of such place.

Protons are located in the nucleus with neutrons. They occupy a massive put thinly packed space.

In the quantum mechanical model, what two words do they use to describe<br> particles?

miskamm [114]

Answer:

This question is incomplete

Explanation:

This question is incomplete but one can assume the answer from the definition of quantum mechanics. Quantum mechanics is the science that describes particles in nature at the atomic and subatomic particle (electron, proton and neutron) level. Thus it can be assumed that atoms and subatomic particles are used to broadly describe particles.

Answer:Macaya (floruit 1802), was a Kongolese-born Haitian revolutionary military leader. Macaya was one of the first black rebel leaders in Saint-Domingue to ally himself with the French Republican commissioners Sonthonax and Polverel. He helped to lead forces that recaptured Cap-Français on behalf of the French Republicans.

Macaya was born in west-central Africa, probably in the Kingdom of Kongo, and taken to the French colony of Saint-Domingue as a slave. After the outbreak of the 1791 slave rebellion in northern Saint-Domingue, Macaya became a lieutenant of an elderly rebel commander named Pierrot. Pierrot's rebel forces were based in the hills outside of Le Cap (Cap Francaise), near Bréda plantation by 1793.

First you need to know what is a semantic memory
Semantic memory, is a more structured record of facts, meanings, concepts and knowledge about the external world that we have acquired.

So ,The element which is a semantic memory is learning from her father that salt water is more dense than fresh water.

Hope this helped :)

Students are attempting to demonstrate a reaction of liquid water separating into hydrogen and oxygen gases:

AlexFokin [52]

Answer:

Explanation:

When water separates into hydrogen and oxygen gas, a decomposition reaction is taking place (one substance breaking apart or breaking down into two or more substances).

The law of conservation of mass tells us that mass is not created or destroyed during a chemical reaction, so the total mass will remain the same. This is supported by the diagram on the page, which shows that in the reactants, there are four hydrogen atoms and two oxygen atoms, and this amount is the same on the product side.

Arrange the following H atom electron transitions in order of increasing frequency of the photon absorbed or emitted:

ololo11 [35]

Hence the order of the transition in order of increasing frequency of the photon absorbed or emitted will be : d < a < c < b

$E = -13.6$ × $Z$ ²/ $n$ ²

where,

$E$ = energy of orbit

n = number of orbit

Z = atomic number

Energy of n = 1 in an hydrogen atom:

$E$ ₁ = -13.6× 1²/1² = -13.6eV

Energy of n = 2 in an hydrogen atom:

$E$ ₂ = -13.6 × 1²/2² = -3.40eV

Energy of n = 3 in an hydrogen atom:

$E$ ₃ = -13.6× 1²/3² = -1.51eV

Energy of n = 4 in an hydrogen atom:

$E$ ₄ = -13.6× 1²/4² = -0.85eV

Energy of n = 5 in an hydrogen atom:

$E$ ₃ = -13.6× 1²/ 5² = -0.54eV

a) n = 2 to n = 4 (absorption)

Δ $E$ ₁ = E₄ - E₂ = -0.85- (- 3.40) = 2.55eV

b) n = 2 to n = 1 (emission)

Δ E₂ = E₁ - E₂ = -13.6 - (- 3.40) = -10.2eV

Negative sign indicates that emission will take place.

c) n = 2 to n = 5 (absorption)

ΔE₃ = E₅ - E₂ = -0.54 -( -3.40) = -2.85eV

d) n = 4 to n = 3 (emission)

ΔE₄ = E₃ - E₄ = -1.51 - (- 0.85) = - 0.66eV

Negative sign indicates that emission will take place.

According to Planck's equation, higher the frequency of the wave higher will be the energy:

$E = hv$

h = Planck's constant

$v =$ frequency of the wave

So, the increasing order of magnitude of the energy difference :

$E$ ₄< E₁ <E₃ <E₂

The H atom electron transitions in order of increasing frequency of the photon absorbed or emitted will be d < a < c < b

: d < a < c < b
