Answer:

42

Explanation:

Divide the distance by the time.

If a dolphin is producing a vocalization with a frequency of 35 Hz, traveling at 1470 m/s, then wavelength of sound is 42m.

Wavelength of sound will be calculated by using the below formula as:

λ = υ / f, where

υ = velocity or speed of sound = 1470 m/s

f = frequency of wavelength = 35 Hz

On putting values we get

λ = 1470 / 35 = 42m

Hence resultant wavelength of sound is 42m.

Answer:

22.656 grams of oxygen gas are there in a 2.3L tank at 7.5 atm and 24° C

Explanation:

An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law:

P * V = n * R * T

where R is the molar constant of the gases and n the number of moles.

In this case you know:

Replacing:

[tex]7.5 atm* 2.3 L=n*0.082 \frac{atm*L}{mol*K} *297K[/tex]

Solving:

[tex]n=\frac{7.5 atm* 2.3 L}{0.082 \frac{atm*L}{mol*K} *297K}[/tex]

n=0.708 moles

Knowing that oxygen gas is a diatomic gas of molecular form O₂ and its mass is 32 g / mole, you can apply the following rule of three: if 1 mole contains 32 grams, 0.708 moles, how much mass will it have?

[tex]mass=\frac{0.708 moles*32 grams}{1mole}[/tex]

mass= 22.656 grams

22.656 grams of oxygen gas are there in a 2.3L tank at 7.5 atm and 24° C

Answer:

The mass of oxygen gas is 22.66 grams

Explanation:

Step 1: Data given

Volume of tank = 2.3 L

Pressure = 7.5 atm

Temperature = 24.0°C = 273 +24 = 297 K

Step 2: Calculate moles oxygen gas

p*V = n*R*T

⇒with p = the pressure of the oxygen gas = 7.5 atm

⇒with V = the volume of the tank : 2.3 L

⇒with n = the moles of oxygen gas = TO BE DETERMINED

⇒with R = the gas constant = 0.08206L*atm/mol*K

⇒with T = the temperature = 297 K

n = (p*V- / (R*T)

n = (7.5 atm * 2.3L) / (0.08206 L*atm/mol*L * 297K)

n = 0.708 moles

Step 3: Calculate mass of oxygen gas

Mass O2 = moles O2 = molar mass O2

Moles O2 = 0.708 moles * 32.0 g/mol

Moles O2 = 22.66 grams

The mass of oxygen gas is 22.66 grams

Well, the big bang theory was that the universe started to expand at and extrmly fast rate. We're talking several billion kilometers in less than a second.  People think that our univers was pretty much shot out into space in a ciertain direction. During this, the univers has expanded and widen't to unimaginable size. but we really don't know what happend, and we may never find out. Who knows?

According to the traditional Big Bang theory, the universe's creation involved a singularity, a region of infinite density and temperature whose nature is difficult for humans to comprehend.

A physics theory called the Big Bang event explains how the cosmos grew from a highly dense and hot starting condition. The evolution of the observable universe from the earliest known times through its succeeding large-scale form is explained by several cosmological models of the Big Bang.

Everything in the cosmos was compressed into a singularity, a point of infinite heat and density, around 13.7 billion years ago. Our cosmos suddenly began to expand explosively, expanding faster than the speed of light.

Belgian Catholic priest, theoretical physicist, mathematician, astronomer, and professor of physics Georges Lemaître is credited with developing the theory itself. The notion was initially supported by Hubble's Law of the universe's expansion.

Thus, in the traditional Big Bang theory, the universe's creation involved a singularity.

Answer:

0.674 mol

Explanation:

Step 1:

Data obtained from the question.

Volume (V) = 4 L

Pressure (P) = 560 kPa

Temperature (T) = 127°C

Number of mole (n) =?

Step 2:

Conversion to appropriate unit.

For pressure:

101.325 KPa = 1 atm

Therefore, 560 kPa = 560/101.325 = 5.53 atm

For temperature:

Temperature (Kelvin) = temperature (celsius) + 273

temperature (celsius) = 127°C

Temperature (Kelvin) = 127°C + 273 = 400K

Step 3:

Determination of the number of mole of Neon.

The number of mole of Neon can be obtained by using the ideal gas equation as follow:

Volume (V) = 4 L

Pressure (P) = 5.53 atm

Temperature (T) = 400K

Gas constant (R) = 0.082atm.L/Kmol

Number of mole (n) =?

PV = nRT

5.53 x 4 = n x 0.082 x 400

Divide both side by 0.082 x 400

n = (5.53 x 4) /(0.082 x 400)

n = 0.674 mol

The number of mole of Neon is 0.674 mol

To find the number of moles of Neon in 4.0 L of neon gas at 560 kPa and 127 °C, the ideal gas law is used, and approximately 0.674 moles of Neon are found.

The student has asked how many moles of Neon would be contained in 4.0 L of neon gas at 560 kPa and 127 °C. To answer this question, we will use the ideal gas law, which can be stated as PV = nRT where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature in Kelvin.

First, convert the temperature from Celsius to Kelvin:

Convert pressure from kPa to atm:

The ideal gas constant, R, is 0.0821 L·atm/mol·K.

Now, rearrange the ideal gas equation to solve for n (moles):

Plugging the values in, we get:

Therefore, there are approximately 0.674 moles of Neon in 4.0 L of neon gas under the given conditions.

Answer: 5.4 moles

Explanation:

Dinitrogen pentoxide has a chemical formula of N2O5

Now, based on Avogadro's law:

1 mole of any substance has 6.02 x 10^23 atoms

So, 1 mole of N2O5 = 6.02 x 10^23 molecules

Z moles of N2O5 = 3.25 x 10 ^ 24 molecules

To get the value of Z, cross multiply:

(3.25 x 10^24 molecules x 1mole) = (6.02 x 10^23 molecules x Z moles)

3.25 x 10^24 = (6.02 x 10^23 x Z)

Z = (3.25 x 10^24) ➗ (6.02 x 10^23)

Z = 5.4 moles

Thus, there are 5.4 moles of Dinitrogen pentoxide.

Answer:

Iodine pentafluoride

Explanation:

Answer:

Iodine pentafluoride

Answer:

202 KPa

Explanation:

Step 1:

Data obtained from the question.

Initial Pressure (P1) = 220 kPa

Initial temperature (T1) = 26.7°C

Final temperature (T2) = 2.2°C

Final pressure (P2) =?

Step 2:

Conversion of the Celsius temperature to Kelvin temperature.

Temperature (Kelvin) = temperature (celsius) + 273

T1 = 26.7°C + 273 = 299.7 K

T2 = 2.2°C = 2.2°C + 273 = 275.2 K

Step 3:

Determination of the new pressure.

The new pressure of the tire can be obtained as follow:

P1/T1 = P2/T2

220/299.7 = P2/275.2

Cross multiply to express in linear form

299.7 x P2 = 220 x 275.2

Divide both side by 299.7

P2 = (220 x 275.2)/299.7

P2 = 202 KPa

Therefore, the new pressure of the tire is 202 KPa

When the temperature drops to 2.2 degrees Celsius, the tire pressure will decrease to approximately 202.1 kPa.

We can use the combined gas law which is derived from the ideal gas law. The combined gas law relates pressure, volume, and temperature without needing to know the quantity of gas, and is expressed as (P₁/T₁) = (P₂/T₂), where P₁ and T₁ are the initial pressure and temperature, and P₂ and T₂ are the final pressure and temperature.

To do so, we first convert temperatures to Kelvin by adding 273.15. Then we rearrange the formula to solve for P₂:

Therefore, the tire pressure will decrease to approximately 202.1 kPa.

Thus, both melting and freezing are physical changes.

Answer: 10L

Explanation:

Given that:

Initial pressure P1 = 1 atm

New pressure P2 = 3 atm

Initial volume V2 = 30 L

New volume V2 = ?

Since pressure and volume are involved, apply the formula for Boyle's law

P1V1 = P2V2

1 atm x 30L = 3 atm x V2

30 atm L = 3 atm x V2

V2 = (30 atm L / 3 atm)

V2 = 10L

Thus, volume changed to 10 liters

If the temperature of a gas changes, but the number of moles and volume remain constant, Pressure also changed. Therefore, option B is correct.
