Among the elementary subatomic particles of physics is the muon, which decays within a few nanoseconds after formation. The muon has a rest mass 206.8 times that of an electron.
Calculate the de Broglie wavelength associated with a muon traveling at a velocity of 8.50×105 cm/s .

Answers

Answer 1

The De Broglie wavelength of the muon is calculated to be 4.13 × 10^10 m

We have the following information;

mass of the muon  (m)= 206.8 × 9.11 × 10^-31 Kg = 1.88 × 10^-28 Kg

Plank's constant(h)  = 6.6 × 10^-34 Js

Velocity of the muon(v) =  8.50×10^5 cm/s or 8500 m/s

From;

λ = h/mv

λ = 6.6 × 10^-34/1.88 × 10^-28 ×  8500

λ = 6.6 × 10^-34/1.598 × 10^-24

λ = 4.13 × 10^10 m

A substance has a freezing point of –38°C and a boiling point of 356°C. At what temperature would this substance be in its liquid state?

A) -100°C
B) -50°C
C) 80°C
D) 375°C

Answers

Answer:

X. 80°

Explanation:

if the substance is below -38 then it is in the solid phase (-100° and -50°) and if it is above 356° it is a gas (375°). Therefore anything in the middle is a liquid, 80°.

Given that the substance freezes at  –38°C and boils at 356°C, it will be a liquid at  a temperature of 80°C.

What is liquid range?

The term liqiid range refers to the temperatire range within which a substance remains in its liquid state. Now we are told that the substance freezes at –38°C and boils at 356°C.

Hence, we expect that this substance will be in the liquid state at a temperature of 80°C.

The best representation of the ozone molecule incorporates both of the structures that you drew in parts C and D.
Redraw the Lewis structures of an ozone molecule and place a two-ended arrow between the structures, pointing to both
of them. This representation is called a resonance structure.

Answers

Answer:

Explanation:

EDMENTUM

The Lewis structure for ozone contains a central oxygen atom that has a double bond to one oxygen atom and a single bond with the other oxygen atom. The resonance structure of the ozone is shown in the attached figure below.

What is the lewis structure of the ozone molecule?

The oxygen molecule has a valency of -2. It can form two-sigma bonds or covalent bonds with the other atoms. Oxygen contains three lone pairs to form π bonds with other atoms. Ozone contains all three oxygen atoms and is a dihedral molecule with sp² hybridization.

Lewis structure is generally based on the octet rule which states that there should be eight electrons in the valence shell or orbit of an atom for a stable molecule.

The lone pair on the central oxygen atom repels the electrons in the two side bonds and adopt a bent molecular geometry. The expected geometry is the trigonal planar with a bond angle is 120°.

In an ozone molecule, six valence electrons for each molecule of Oxygen so the total number of valence electrons is 6 × 3 = 18. As both Oxygen atoms on the sides have the same electronegativity, therefore, the double bond keeps on shifting from both causing resonances.

Determine the mass percentage of carbon, C, hydrogen, H, and oxygen, O, in C6H8O7. Refer to the periodic table for the atomic mass of each element.

Answers

Answer:

C=37.5% H=4.2% O=58.3%

Explanation:

molar mass of element / molar weight of compound X 100% (for each element)

C mass = 12 x 6 = 72

H mass = 1 x 8 = 8

O mass =16x 7 = 112

Molar weight of compound = 192

72/192(100%)= 37.5% C

8/192(100%) = 4.2 % H

112/192 (100%) = 58.3% O

The mass percentage of carbon, hydrogen, H, and oxygen, O, in C₆H₈O₇ is C = 37.5% H = 4.2% O = 58.3%.

What is the mass percentage?

The concentration of an element in a compound or component in a combination is calculated by the mass percentage.

The collective of a component is divided by the entire mass of the mixture to obtain the mass percentage, which is then multiplied by 100%.

Given, finding the mass percentage of carbon, hydrogen, H, and oxygen, O, in C₆H₈O₇

the molar mass of element / molar weight of compound X 100% (for each element

First, calculate the molar mass of the elements given in the compound.

C mass = 12 x 6 = 72

H mass = 1 x 8 = 8

O mass =16x 7 = 112

Molar weight of compound = 192

72/192(100%)= 37.5% C

8/192(100%) = 4.2 % H

112/192 (100%) = 58.3% O

Thus, the mass percentage is C = 37.5% H = 4.2% O = 58.3%.

Jim makes a table that lists soluble and insoluble substances. Which statement best explains why the table is incorrect?

a table with the titles Soluble and Insoluble, written underneath Soluble is sugar, food coloring, and honey, and written underneath Insoluble is sand, grass, and salt

A. Food coloring is an insoluble substance.
b. Honey is an insoluble substance.
C. Grass is a soluble substance.
D. Salt is a soluble substance.

Answers

Answer:

D

Explanation:

The statement that best explains why the table is incorrect is: Grass is a soluble substance. Option C is correct.

In the table, grass is listed under "Insoluble," but in reality, grass is not a substance that dissolves in water. It is a complex mixture of various compounds, including cellulose and other organic materials, which are not water-soluble. Grass does not dissolve when added to water; instead, it remains intact and is not readily soluble.

On the other hand, all the other substances listed in the table are correctly categorized. Sugar, food coloring, and honey are soluble substances because they dissolve in water. Sand and salt are insoluble substances because they do not dissolve in water.

Hence, C. is the correct option.

How many moles of carbon are 8.7x1023 atoms of carbon?

Answers

You’ll need to set up a convention from moles over atoms to atoms over moles

One mole of every substance contains 6.022×10²³ number of atoms. One mole carbon have these much atoms and thus number of moles of carbon having 8.7 × 10²³ atoms is 1.44 moles.

What is carbon?

Carbon is 6th element in periodic table. It is a p block element and is a non-metal. Carbon forms covalent bonds with other elements.

One mole of every elements contains 6.022×10²³ number of atoms and it is called Avogadro number. Similarly one mole of a compound contains 6.022×10²³ number of molecules.

The number of atoms in one mole of carbon is 6.022×10²³.Therefore, number of moles of carbon which contains 8.7 × 10²³ atoms is calculated as follows:

number of moles of carbon = 8.7 × 10²³/6.022×10²³

                                              = 1.44 moles.

Therefore, the number of moles of carbon containing 8.7 × 10²³ atoms is 1.44 moles.
