Calculate The Wavelength Of Light Produced If An Electron Moves From N=6 State To N=5 State Of An Electron
Answer 2

The wavelength of light produced if an electron moves from n=6 state to n=5 state of an electron in a hydrogen atom is 7.59 × [tex]10^-6[/tex] m

Using the Rydberg formula;

1/λ = 1.09737 × [tex]10^-6[/tex] (1/[tex]nf^2[/tex] - 1/[tex]ni^2[/tex])

Where;

λ = wavelength

nf = final state of the electron

ni = initial state of the electron

Substituting values;

1/λ = 1.09737 × [tex]10^7[/tex] ([tex]1/5^2[/tex] - [tex]1/6^2[/tex])

1/λ = 1.09737 × [tex]10^7[/tex] (1/25 - 1/36)

1/λ = 1.09737 × [tex]10^7[/tex] (0.04 - 0.028)

1/λ = 1.09737 × [tex]10^7[/tex] (0.012)

λ = 7.59 × [tex]10^-6[/tex] m

Answer:

C

Explanation:

'Ordered Arrangement' basically means that it is a solid at room temperature. Room temperature is approximately 15-20C so we are looking for melting and boiling points that are above room temperature so it hasn't/can't melt or boil at room temperature and would therefore be solid. Option C is the only one where both points are temperatures above room temperature therefore option C is the only one where the substance would be in an 'ordered arrangement' at room temperature.

You have developed a promising anti-cancer agent, but it has poor solubility in water. Which of the following changes should improve water solubility? ( there is two possible answers)a) adding a methyl groupb) adding a hydroxyl groupc) adding a carboxyl groupd) increasing the size of the druge) adding a benzene ring

Answers

Answer:

adding a hydroxyl group

adding a carboxyl group

Explanation:

The addition of a hydroxyl or a carboxyl group to the molecule will increase its solubility. This is because, the -OH group will form hydrogen bonds with the water molecules. The formation of such hydrogen bonds will lead to improvement in the solubility of the anti cancer agent and solve the problem of poor solubility of the anticancer agent in water.

A biochemical reaction will proceed in the direction as written if:_______a. ΔG > 0.b. ΔH > 0.c. ΔG = zero.d. ΔG < 0.e. ΔH < 0.

Answers

Answer:

ΔG < 0

Explanation:

The condition for spontaneity of a chemical reaction is that ∆G<0. Hence for any biochemical reaction to proceed as written, ∆G must have a negative value.

If ∆G >0, the reaction is not spontaneous and will not proceed as written. ∆G=0 means that the reaction has attained equilibrium.

The solar wind is made up of ions, mostly protons, flowing out from the Sun at 400 km/s. Near Earth, each cubic kilometer of interplanetary space contains, on average, 6 x 10^15 solar-wind ions. How many moles of ions are in a cubic kilometer of near-Earth space?

Answers

Answer:

9.96x10⁻⁹ moles of ions are in a cubic kilometer

Explanation:

As the problem states, in the near-earth space there are 6x10¹⁵ ions.

Moles are an amount of substance defined as 6.022x10²³. 1 mole of ions are 6.022x10²³ ions

1 mole of substance is 6.022x10²³ particles.

As there are 6x10¹⁵ ions in a cubic kilometer, the moles are:

6x10¹⁵ ions * (1mol / 6.022x10²³ ions) =

9.96x10⁻⁹ moles of ions are in a cubic kilometer

Based on the formula for calculating moles of particles, there are 9.96 * 10⁻⁹ moles of ions in a cubic kilometer of  interplanetary space.

What is the moles of ions?

The moles of ions is determined using the formula below:

Moles of a particle = number of particles / 6.02 * 10²³

Data provided:

Number of ions = 6 * 10¹⁵ ions

Moles of ions =  6 * 10¹⁵ ions/6.02 * 10²³

moles of ions = 9.96 * 10⁻⁹ moles of ions.

Therefore, there are 9.96 * 10⁻⁹ moles of ions in a cubic kilometer of  interplanetary space.

Arrange the compounds by boiling point. a. A pentane molecule with the condensed structure CH3CH2CH2CH2CH3. b. A neopentane molecule with the condensed structure C(CH3)4. c. A hexane molecule with the condensed structure CH3CH2CH2CH2CH2CH3.

Answers

Answer:

Hexane > pentane > neopentane

Explanation:

The boiling point of alkanes varies with chain length. The greater the length of the chain, the greater its boiling point.

Since hexane consists of a longer chain than pentene, its boiling point is definitely higher than that of pentane.

Similarly, neopentane is a branched alkane, the boiling point of a branched alkane is always lower than that of its straight chain counterparts.

Hexane has the highest boiling point due to its higher molecular weight, followed by pentane, and neopentane has the lowest boiling point due to its highly branched structure.

The boiling point is primarily influenced by two factors: molecular weight and branching. The higher the molecular weight, the stronger the van der Waals forces and, therefore, the higher the boiling point. Branching in a molecule tends to disrupt the intermolecular forces, reducing the boiling point.

Hexane has a higher molecular weight than pentane, so it would generally have a higher boiling point than pentane.

Neopentane is highly branched, with four methyl (CH3) groups attached to the central carbon. This branching significantly disrupts the intermolecular forces, reducing the boiling point compared to straight-chain molecules like pentane and hexane.

Benzene has a heat of vaporization of 30.72 kj/mol and a normal boiling point of 80.1 oC. At what temperature does benzene boil when the external pressure is 490 torrtorr?

Answers

Answer:

THE TEMPERATURE AT THE EXTERNAL PRESSURE OF 490 TORR IS 550.72 C

Explanation:

Heat of vaporization = 30.72 kj/mol

Normal boiling point = 80.1 C

Pressure = 490 torr

So therefore, with the above variables given, the relationship between heat of vaporization, pressure and temperature is given by this equation:

ln (P2/P1) = - ^H vap/ R ( 1/ T2 - 1/T1)

H vap = 30.72 kj/mol

P1 = 760 torr ( this is so because the normal boiling point occurs at the vapor pressure equal to the atmospheric pressure which value is 760 torr)

T1 = 80.1 + 273 = 353.1 K

P2 = 490 torr

R = 8.314 J/mol K

T2 = unknown

Re-arranging the formula bu=y making T2 the subject of the equation, we have;

T2 = 1 / (1/T1) - (R / Hvap) (ln (P2/P1))

Introducing the variables into the equation, we have:

T2 = 1 / (1 / 353.1 ) - (8.341 / 30.72 * 10 ^3) ln (490 / 760)

T2 = 1/ (0.00283 - 0.27* 10^-3 ln 0.6447)

T2 = 1 / 0.00283 - 0.27*10^-3 (- 0.43897)

T2 = 1 / 0.00283 + 0.1185 * 10 ^-3

T2 = 1 / 0.1214 *10^-3

T2 = 1 / 0.001214

T2 = 823.72

T2 = 823.72 - 273 = 550.72 C

The temperature when the external pressure is 490 torr is 550.72 C

A 515cm^3 flask contains 0.460 g of a gas at a pressure of 153 kPa and a temperature of 322K. What is the molecular mass of this gas

Answers

Answer:

Molecular mass, [tex]M=28.89\ \text{g/mol}[/tex]

Explanation:

Given that,

Mass of gas, m = 0.46 g

Volume of the container, V = 515 cm^3

Pressure, P = 153 kPa

Temperature, T = 322 K

We need to find the molecular mass of this gas. We know that,

PV =nRT

n = no of moles

[tex]n=\dfrac{PV}{RT}\\\\n=\dfrac{153\ kPa\times 0.515\ L}{8.31447\ LkPaK^{-1}{mol^{-1}}\times (322+273)\ K }\\\\n=0.01592\ \text{moles}[/tex]

No of moles = mass/molecular mass

Let molecular mass is M

[tex]M=\dfrac{m}{n}\\\\M=\dfrac{0.46}{0.01592}\\\\M=28.89\ \text{g/mol}[/tex]

So, the molecular mass of this gas is [tex]28.89\ \text{g/mol}[/tex]

Why do minerals with metallic bonds conduct electricity so well?

Answers

Answer and Explanation:

Because metallic bonding involves delocalized electrons. It is described as a "sea of electrons", because the electrons are not confined around the nucleus of metal atoms, but they are delocalized: thay can be located in one nucleus and then in another neighbor atom. Thus, the electrons have more freedom to move from one part of the metal to another and electricity is well conducted.
