air is trasferred from 75 L tank where the pressure is 125 psi and the temperature is 288 K to a tire with a volume. of 6.1 L and a pressure of 25 psi. what is the new temperature ?

Answers

Answer 1

Answer:

4.7K

Explanation:

Given parameters:

Initial volume  = 75L

Initial pressure  = 125psi  

        to atm gives 8.5atm

Initial temperature  = 288K

New volume  = 6.1L

New pressure  = 25psi

        to atm gives 1.7atm

Unknown:

New temperature = ?

Solution:

To solve this problem, we use the combined gas law which is given below:

        [tex]\frac{P1 V1}{T1}[/tex]    = [tex]\frac{P2 V2}{T2}[/tex]  

P, V and T are pressure, volume and temperature

1 and 2 are initial and new states

                  [tex]\frac{8.5 x 75}{288}[/tex]   = [tex]\frac{1.7 x 6.1}{T2}[/tex]

        T2  = 4.7K

The equilibrium constant is the ratio of concentration or pressure between the product and the reactant with each reaction coefficient raised  

The equilibrium constant is based on the concentration (Kc) in a reaction

Leopard seals are animals adapted to survive in the freezing conditions of Antarctica. Individual leopard seals vary in their different traits.
Which of the following variations would give a leopard seal the greatest chance of surviving in its harsh environment?
A. More spots on its coat. B. Thicker layer of blubber
C. More elongated head
D. Wider, flatter teeth

Answers

Answer:

B. Thicker layer of blubber

Explanation:

For the leopard seals to survives this harsh environment, it must have a thicker layer of blubber

Blubber is a thick layer of fat. It is called the adipose tissues and found in most marine organisms.

This layer helps in insulating the body against heat loss. By so doing, the animal is able to conserve internal heat. They have low thermal conductivity and do not easily lose heat or gain heat as such.

Select one:

(RT)-1.5
RT

Answers

Kp/Kc = RT

Further explanation

Given

Reaction

A(g) ⇌ C(g)+B(g)

Required

Kp/Kc

Solution

For reaction :

pA + qB ⇒ mC + nD  

[tex]\large {\boxed {\bold {Kc ~ = ~ \frac {[C] ^ m [D] ^ n} {[A] ^ p [B] ^ q}}}}[/tex]

While the equilibrium constant Kp is based on the partial pressure  

[tex]\large {\boxed {\bold {Kp ~ = ~ \frac {[pC] ^ m [pD] ^ n} {[pA] ^ p [pB] ^ q}}}}[/tex]

The value of Kp and Kc can be linked to the formula '  

[tex]\large {\boxed {\bold {Kp ~ = ~ Kc. (R.T) ^ {\Delta n}}}}[/tex]

R = gas constant = 0.0821 L.atm / mol.K  

Δn=moles products - moles reactants or

number of product coefficients-number of reactant coefficients  

For reaction :

A(g) ⇌ C(g)+B(g)

number of product coefficients = 1+1=2

number of reactant coefficients   = 1

Δn= 2 - 1 =1

So Kp/Kc = RT

Suppose your metal sample is hammered into the shape of a thin coin with a diameter of 8.62 cm. Determine the thickness (in mm) of this metal sheet. Use the measured metal mass and true denisty of your metal for this calculation.
measured metal mass: 83.956 g
true density: 8.90 g/cm3

Answers

Answer:

The thickness of the metal sheet is 0.162 centimeters.

Explanation:

If mass within the coin is uniformly distributed, then the density ([tex]\rho[/tex]), measured in grams per cubic centimeter, can be represented by the following formula:

[tex]\rho = \frac{m}{\frac{\pi}{4}\cdot D^{2}\cdot z }[/tex] (1)

Where:

[tex]m[/tex] - Mass, measured in grams.

[tex]D[/tex] - Diameter, measured in centimeters.

[tex]z[/tex] - Thickness, measured in centimeters.

If we know that [tex]m = 83.956\,g[/tex], [tex]D = 8.62\,cm[/tex] and [tex]\rho = 8.90\,\frac{g}{cm^{3}}[/tex], then the thickness of the coin is:

[tex]z = \frac{m}{\frac{\pi}{4}\cdot D^{2}\cdot \rho }[/tex]

[tex]z = \frac{83.956\,g}{\frac{\pi}{4}\cdot (8.62\,cm)^{2}\cdot \left(8.90\,\frac{g}{cm^{3}} \right) }[/tex]

[tex]z = 0.162\,cm[/tex]

The thickness of the metal sheet is 0.162 centimeters.

D) 8.648 x 1023
E) 3.134 x 1025

Answers

Answer:

B) 1.183

Explanation:

To convert from grams (mass) to moles, we need to divide by the atomic mass (amu)..

The amu of [tex]CO_{2}[/tex]  is 44.008

52.06/44.08 = 1.182966733

This can be rounded to 1.1830 moles of CO2

1.183 moles of carbon dioxide are there in 52.06 g of carbon dioxide.

Explanation:

Moles of substance are defined ratio of the given mass of the substance to the molar mass of the substance.

Given :

The 52.06 grams of carbon dioxide.

To find :

The moles of carbon dioxide.

Solution:

The mass of carbon dioxide = 52.06 g

The molar mass of carbon dioxide = 44.01 g/mol

The moles of carbon dioxide:

[tex]=\frac{52.06 g}{44.01 g/mol}=1.183 mol[/tex]

When these ions are removed, the ionic equation is called the net ionic equation

Answers

Explanation:

Mole ratio of NaOH to H2O = 2 : 1

Moles of H2O = 1.85mol * (1/2) = 0.925mol.

Mass of H2O = 0.925mol * (18g/mol) = 16.65g.

Answer:

16.65 grams of water can be produced with 1.85 moles of NaOH.

Explanation:

Mole ratio of NaOH to H2O = 2 : 1

Number of moles of water = (1/2)×1.85= 0.925 moles

Molar mass of water (H2O) = 18g/mol

Mass of the right water = 18g/mol×0.925 mol=16.65 grams

What is creating our Earth's Magnetic field?

2) Our Earth having a stationary inner core
3) Our Earth having rocky center
4) All of the above

Answers

Answer:

1) Our Earth's iron liquid outer core rotating around the solid inner core

Explanation:

The earth's magnetic field or the geomagnetic field is produced as a result of the earth's iron liquid outer core rotating around the solid inner core.

This produces the earth's magnetic field.

The earth's core is made up of solid and liquid region. Only the densest elements are found within this region. So, the core is made up of metals which are mainly iron and nickel. The outer core is liquid or molten iron and the inner core is solid. The molten iron and nickel in the outer core moves around the inner core and generates the currents which induces a magnetic field round the earth.
