The statement that describes the 3d, 4s, and 4p orbitals of arsenic (as) based on its electronic configuration and position in the periodic table is; The 3d and 4s orbitals are completely filled, and the 4p orbital is partially filled.

The electronic configuration of arsenic is given as; 1s² 2s² 2p^(6) 3s² 3p^(6) 4s² 3d^(10) 4p³.

Now we can see that in that electronic configuration the orbitals are, s, p and D.

Now, the maximum electrons for each of the 3 orbitals are;

Maximum electrons for d orbital = 10 electrons

Maximum electrons for s orbital = 2 electrons

Maximum electrons for p orbital = 6 electrons.

Now, when we compare the maximum number of electrons for each orbital to the ones in electron configuration of arsenic, it is clear from the last 3 orbitals that the 3d and 4s orbitals are completely filled while the 4p orbital is half filled or partially filled.

The probability that maya's first guess is correct and her second guess is incorrect is 0.24

From the question given above, the following data were obtained:

Next, we shall determine the probability that her 1st guess is correct.

P(C) = nC / nS

P(C) = 222 / 555

Next, we shall determine the probability that her 2nd guess is incorrect

P(I) = nI / nS

P(I) = 333 / 554

Finally, we shall determine the probability that her first guess is correct and her second guess is incorrect.

P(C n I) = P(C) × P(I)

P(C n I) = (222 / 555) × (333 / 554)

Magnesium bromide is the inorganic compound with the formula Mgbr₂, where 2 indicates that there are 2 bromide ions for every magnesium.

Magnesium bromide (MgBr2) is an ionic compound of magnesium and bromine, that is, it is the compound that is formed when an atom with low electronic affinity gives up electrons, becoming an anion, while another atom gains those electrons.

Therefore, we can conclude that magnesium bromide is a compound where for each magnesium ion there are 2 bromide ions.

The rock cycle describes how rocks change as a result of natural processes. The rock cycle forms new rocks using the crystallization, erosion and compaction processes. This makes the correct answer: D: all of the above. Igneous rocks for example are rocks formed from the crystallization( formation of rock crystals in cooling magma) of a liquid. Sedimentary rocks are formed by erosion. However, in order to form a sedimentary rock, the accumulated sediment must become compacted and cemented together.

When describing a strange dream that you had, there are several ways to go about it and this is one:

Writing an essay can be academic dishonesty so I will walk you through how to write one yourself.

Introducing yourself does not mean saying your name. You can simply use the pronoun, "I." Talk about what you were doing, for instance, walking home, or watching television.

Then talk about how you fell asleep - could be in your bed, on a seat on the bus, or even on a sitting room couch.

Then begin to talk about how the dream started. Talk about how the dream began and then progressed till you get to the strange events.

Talk about these strange events and end on the strangest; then explain why this scene was strange if it isn't apparent.

It is best to either use little detail or a lot of detail, avoid the middle ground.

Answer: The mass of carbon dioxide is 28.6 grams

Explanation:  Step 1: Data given

Mass of O2 = 41.6 grams

Volume of the O2 container = 2V

Volume of the CO2 container = V

Pressure and temperature are the same

Step 2: Ideal gas law

The ideal gas law = p*V=nRT

For O2: p*2V = n(O2)*R*T

For CO2: p*V = n(CO2)*R*T

n(O2)*R*T / P*2V = n(CO2)*R*T / P*V

Since P, R and T are contstant, we can simplify this to:

n(O2)/2 = n(CO2)

Step 3:  Calculate moles of O2

Moles O2 = mass O2/ Molar mass O2

Moles O2 = 41.6 grams / 32 g/mol

Moles O2 = 1.3 mol O2

The number of moles CO2 = 0.65 mol

Mass of CO2 = Moles CO2 * Molar Mass CO2

Mass of CO2 = 0.65 mol * 44.01 g/mol

Mass of CO2 = 28.6 grams

The mass of carbon dioxide is 28.6 grams

The center of gravity for the three-objects system is approximately located

at their center of mass.

Reasons:

The coordinates of the vertices of the objects and their masses are;

The rod:

Vertices, (2, 7), and (9, 7)

Mass, m₁ = 6.00 kg.

The right triangle;

Vertices; (4, 1), (8, 5), (8, 1)

Mass, m₂ = 3.00 kg.

The square

Vertices; (-5, 5), (-2, 5), (-2, 2), (-5, 2)

Mass, m₃ = 5.00 kg

Required;

The center of gravity for the three-object system.

Solution:

The center of gravity is given by the formula;

[tex]\displaystyle X_c =\mathbf{ \frac{X_{c1} \times m_1 +X_{c2} \times m_2 +X_{c3} \times m_3 }{m_1 + m_2 + m_3}}[/tex]

[tex]\displaystyle Y_c =\mathbf{ \frac{Y_{c1} \times m_1 +Y_{c2} \times m_2 +Y_{c3} \times m_3 }{m_1 + m_2 + m_3}}[/tex]

Where;

[tex]X_{c1}[/tex] = The x-coordinates of the center of the rod = 5.5

[tex]X_{c2}[/tex] = The x-coordinate of the centroid of the triangle  [tex]\displaystyle = \frac{4 + 8 + 8}{3} = \frac{20}{3}[/tex]

[tex]X_{c3}[/tex] = The x-coordinate of the centroid of the square = (-5 - (-2)) ÷ 2 - 2 = -3.5

[tex]Y_{c1}[/tex] = The y-coordinate of the center of the rod = 7

[tex]\mathbf{ Y_{c2}}[/tex] = The y-coordinate of the centroid of the triangle  [tex]\displaystyle = \frac{7}{3}[/tex]

[tex]Y_{c3}[/tex] = The y-coordinate of the centroid of the square = 3.5

Therefore;

[tex]\displaystyle X_c = \mathbf{ \frac{5.5 \times 6 +\frac{20}{3} \times 3 +(-3.5) \times 5 }{6+ 3 + 5}} \approx 2.58[/tex]

[tex]\displaystyle Y_c = \mathbf{ \frac{7 \times 6 +\frac{7}{3} \times 3 +3.5 \times 5 }{6+ 3 + 5}} = 4.75[/tex]

The center of gravity for the three-object system is ([tex]X_c[/tex], [tex]Y_c[/tex]) ≈ (2.58, 4.75)
