The electronic configuration of magnesium is:

1s² 2s² 2p⁶ 3s² = [Ne] 3s²

This means that for a magnesium atom, in order to have its outermost orbital full, the easiest way would be to lose the two outermost electrons. This is seen in its relatively low first two ionization energies. The third ionization energy is several times higher because the ion would move from a stable form to an highly unstable form. (Mg⁺² → Mg⁺³ + e⁻).

Sodium only has one electron in its outermost orbital, so its first ionization energy would be several times lower than the second.

The average atomic mass of her sample is 114.54 amu

Let the 1st isotope be A

Let the 2nd isotope be B

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

The average atomic mass of the sample can be obtained as follow:

[tex]Average \: atomic \: mass \: = \frac{mass \: of \: A \times A\%}{100} + \frac{mass \: of \: B \times B\%}{100} \\ \\ Average \: atomic \: mass \: = \frac{113.6459\times 59.34}{100} + \frac{115.8488\times 40.66}{100} \\ \\ Average \: atomic \: mass \: = 114.54 \: amu \\ \\ [/tex]

Thus, the average atomic mass of the sample is 114.54 amu

When oxygen -15 nucleus undergoes beta emission, it is transformed into Fluorine - 15 nucleus.

Beta decay is said to occur when a neutron is converted to a proton. This process leads to the emission of en electron. The neutron - proton ratio decreases and the atomic number of the daughter nucleus is greater than that of the parent nucleus by one  unit.

Hence, when oxygen -15 nucleus undergoes beta emission, it is transformed into Fluorine 15 nucleus.

Explanation:

Answer:

Hey! The correct answer is D.) Different vibrations in the ear cause the brain to interpret different sounds.

Explanation:

Answer:

Q= ms∆T

Where, m is mass of substance

S is specific heat

∆T is temperature change

As in question , m=8.21 ,s=0.13 ,∆T =6.2

So, Q = 8.21×0.13×6.2=6.61 J

The ratio of molecules in sulphur dioxide and methane will be the same as the ratio of their moles. So, first of all we should find out the number of moles of sulphur dioxide in 1 gram of sulphur dioxide in 1 gram of sulphur dioxide, and the number of moles of methane in 1 gram of methane. This can be done as follows :

(i) The molecular formula of sulphur dioxide is [tex]SO_{2}[/tex]

So, [tex]1[/tex]  mole of [tex]SO_{2}[/tex] = [tex]Mass[/tex] [tex]of[/tex] [tex]2'O'[/tex]

[tex]=32+2*16[/tex]

[tex]= 64[/tex] grams

Now, [tex]64g[/tex] of sulphur dioxide [tex]= 1[/tex] mole

So, [tex]1g[/tex] of sulphur dioxide = [tex]\frac{1}{64}[/tex] mole

Thus, we have [tex]\frac{1}{64}[/tex] mole of sulphur dioxide and it contains molecules in it. Now, since equal moles of all the substance contain equal number of molecules, therefore, [tex]\frac{1}{64}[/tex] mole of methane will also contain x molecules of methane.

(ii) Molecular formula of methan is [tex]CH_{4}[/tex]

So, 1 mole of [tex]CH_{4}[/tex]  = Mass of C + Mass of 4 H

[tex]=12+4*12[/tex]

Now, 16g of methane = 1 mole

So, 1 g of mathane = [tex]\frac{1}{16}[/tex] mole

We know that:

[tex]\frac{1}{64}[/tex] mole of methane contains = x molecules

So, [tex]\frac{1}{16}[/tex]  mole of contains will contain =[tex]\frac{x*64}{16}[/tex] molecules

=[tex]4x[/tex] molecules

Explanation:

asteroids most often leave trails due to the large amount of friction that occurs.

The bright spatial object with a tail moving fastly across the sky is called a comet. Comets are made of rock, dust and ices.

Comets are orbiting snowballs around sun made of frozen gases, rock, and dust. They enlarge to the size of a sizable town when frozen. A comet heats up and ejects dust and gases into a huge, blazing head that is larger than most planets when its orbit puts it near to the Sun.

Millions of kilometers away from the sun, the dust and gas combine to form a tail. The Kuiper Belt and much further Oort cloud are presumably home to billions of comets that orbit our sun.

Some of their ice begins to melt and boil off as the comet approaches the sun, along with some dust. The coma, which is created by these particles and gases, surrounds the nucleus.

A) The answer to whether an average-size, single-family home be built with one day’s output from the saw mill is; No, it can't be built from one days output

B) The number of days will it take for the saw mill to produce enough lumber to build a neighborhood of 100 average-size homes is; 1100 days

A) From research, the average size capacity saw mill usually produces around 1500 board feet of boards per day.

Now, converting board ft to cubic meter gives;

1 board feet = 1/424 m³

Thus; 1500 board feet = 1500 * 1/424 ≈ 3.54 m³

Now, we are told that it takes 38 m³ of boards and plywood to build an average size single family home.

Since one days output = 3.54 m³

It is less than the volume required for the average sized house and so the daily output will not be sufficient.

B) Number of days to produce enough boards and plywood for the average sized family home = 38/3.54 ≈ 11 days

Thus, for 100  homes;

Number of days = 100 * 11 = 1100 days

This question is recalling the behavior of real gases in contrast to ideal gases, defined by the van der Waals equation and the ideal gas law respectively, and a reason behind the increasing discrepancy is required.

In such a way, we can start by considering the attached picture in which the choices are shown and clearly, the answer is "as the polarity of the molecules increase".

The aforementioned can be explained with the concept of intermolecular forces, because ideal gas theory states that ideal gas molecules do not interact one to another, and, as the polarity of the molecules increase, these intermolecular forces increase their frequency and strength, and will lead to the formation of associations, which fail to be numerically modelled by simple equations of state such as van der Waals, Redlich-Kwong, Peng-Robinson, etc,.

These associations are, of course, thoroughly neglected by the ideal gas law whereas the ones included in the van der Waals equation, which are not the most reliable, merely attempt to approach this phenomenon, which cause the mentioned discrepancy. As an additional data, robust equations of state, such as CPA (cubic plus association) are able to provide reliable results when working with highly polar gases but turn out really tough to work with due to its mathematical complexity.

The molarity of the NaOH solution is 0.03 M

We'll begin by calculating the mole of the KHP

Mole = mass /molar mass

Mole of KHP = 0.212 / 204.22

Mole of KHP = 0.001 mole

Next, we shall determine the molarity of the KHP solution

Molarity = mole / Volume

Molarity of KHP = 0.001 / 0.05

Molarity of KHP = 0.02 M

Finally , we shall determine the molarity of the NaOH solution

KHP + NaOH —> NaPK + H₂O

From the balanced equation above,

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

MaVa / MbVb = nA / nB

(0.02 × 50) / (Mb × 35) = 1

1 / (Mb × 35) = 1

Cross multiply

Mb × 35 = 1

Divide both side by 35

Mb = 1 / 35

Mb = 0.03 M

Thus, the molarity of the NaOH solution is 0.03 M
