0.500 L of a gas is collected at 2911 MM and 0°C. What will the volume be at STP?

Answers

Answer 1

Answer:

V₂ =  1.92 L

Explanation:

Given data:

Initial volume = 0.500 L

Initial pressure =2911 mmHg (2911/760 = 3.83 atm)

Initial temperature = 0 °C (0 +273 = 273 K)

Final temperature = 273 K

Final volume = ?

Final pressure = 1 atm

Solution:

Formula:  

P₁V₁/T₁ = P₂V₂/T₂  

P₁ = Initial pressure

V₁ = Initial volume

T₁ = Initial temperature

P₂ = Final pressure

V₂ = Final volume

T₂ = Final temperature

by putting values,

V₂ = P₁V₁ T₂/ T₁ P₂  

V₂ = 3.83 atm × 0.500 L × 273 K / 273 K × 1 atm

V₂ = 522.795 atm .L. K / 273 K.atm

V₂ =  1.92 L

Kelle & Jenn are at a pool. Kelle is standing on the high diving board while Jenn is standing on the low diving board. Assuming the difference in weight/mass is negligible, which of the following statements accurately describes this relationship?

A. Kelle has a greater potential energy than Jenn.
B. Jenn & Kelle have equal potential energies.
C. Jenn has a greater potential energy than Kelle.
D. Kelle has a greater kinetic energy than Jenn.

Answers

Answer:

A. Kelle has a greater potential energy than Jenn.

Explanation:

We need to apply the kinetic energy equation here to solve this problem: P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

The problem tells us, however, that mass/weight is negligible; therefore, the only thing that really matters here is the height. Kelle is higher up, so she would have a greater potential energy than Jenn, who is lower.

Pb(SO4)2 + 4 LiNO3 → Pb(NO3)4 + 2 Li2SO4
If 2.25 moles of lead (II) sulfate are combined with 9.62 moles of lithium nitrate, how moles of lithium sulfate can be created? please help

Answers

Answer:

4.5 moles of lithium sulfate are produced.

Explanation:

Given data:

Number of moles of lead sulfate = 2.25 mol

Number of moles of lithium nitrate = 9.62 mol

Number of moles of lithium sulfate = ?

Solution:

Chemical equation:

Pb(SO₄)₂ + 4LiNO₃      →     Pb(NO₃)₄ + 2Li₂SO₄

Now we will compare the moles of lithium sulfate with lead sulfate and lithium nitrate.

                       Pb(SO₄)₂        :         Li₂SO₄

                            1                :             2

                          2.25           :          2/1×2.25 = 4.5 mol

                       LiNO₃            :             Li₂SO₄

                           4                :                2

                           9.62           :             2/4×9.62 = 4.81 mol

Pb(SO₄)₂  produces less number of moles of Li₂SO₄ thus it will act as limiting reactant and limit the yield of  Li₂SO₄.

How many molecules are in 33.6 liters of neon (Ne) gas at STP?

Answers

Answer:

moles or atoms?

Explanation:

you can't have a molecule of any so there's two different answers that I can give you:

how many moles? 1.5

how many atoms? 9.03x10^23 atoms

At STP 1 mole of an ideal gas occupies 22.4L.

33.6 L x 1 mol/22.4 L = 1.5 moles of Neon

1.5 moles Ne x 6.02x1023 atoms/mole = 9.03x1023 atoms

9.03x10²³ molecules are in 33.6 liters of neon (Ne) gas at STP. At STP 1 mole of an ideal gas occupies 22.4L.

What is atom?

The smallest unit of matter that may be split without producing electrically charged particles is the atom. It is also the smallest piece of substance with chemical element-like characteristics. Electric forces, which link electrons towards the nucleus of atoms, cause them to be drawn to any positive charge.

Space makes up the majority of an atom. The remainder is made up of a cloud of negatively charged electrons around a positively charged nucleus made up of protons and neutrons. Compared to electrons, that are the smallest charged particles in nature, the nucleus is tiny and dense.  

At STP 1 mole of an ideal gas occupies 22.4L.

33.6 L x 1 mol/22.4 L = 1.5 moles of Neon

1.5 moles Ne x 6.02x10²³ atoms/mole = 9.03x10²³ atoms

Therefore, 9.03x10²³ molecules are in 33.6 liters of neon (Ne) gas at STP.

The specific heat of aluminum is 0.88 J/g°C. How many joules will it take to make the temperature of a 50. g nugget go up from 20.°C to 70.°C?

Answers

Answer:

2200J

Explanation:

Given parameters:

Specific heat of aluminum  = 0.88J/g°C

Mass of nugget  = 50g

Initial temperature  = 20°C

Final temperature  = 70°C

Unknown:

Quantity of heat required for the heating = ?

Solution:

To solve this problem, we use the expression below;

       H  = m c Δt

H is the quantity of heat

m is the mass

c is the specific heat capacity

Δt is the change in temperature

        H  = 50 x 0.88 x (70 - 20) = 2200J

Why is the organization of the periodic table by physical properties not very useful?

Answers

Answer:

It shows no regular pattern

Explanation:

Physical properties of an element are those we can observe and feel with our senses. Also, the use special equipment can enhance our perception of these properties.

The same physical property can be shared different number elements. On the periodic table, all the elements in group 1 and 2 are metals. This is not very useful for scientists whose emphasis is to distinguish one atom from the other. Therefore, physical properties are highly limited in the organization of the periodic table.

This means in order for the object to heat up it will have to have a temperature that is less than the temperature in the room. Ice cubes, glass of tea, and butter are the three objects that have a temperature less than 72 degrees so when they are placed in the 72 degrees room they will heat gain heat (therefore making the molecules move faster)

Gas stoichiometry a sample of methane gas having a volume of 2.80 L at 25c and 1.65 atm was mixed with a sample oxygen gas having a volume 35.0L at 31c and 1.25 atm . The mixture was then ignited to form carbon dioxide and water . Calculate the volume of co2 formed at a pressure of 2.50 atm and a temperature of 125 c

Answers

Answer:

2.47 L. CO2

Explanation:

First, let's establish what we need to find. The volume of CO2 formed at a pressure of 2.50 atm and a temperature of 125 C. Now, don't let this overwhelm you. To find the volume of CO2 formed, we must first find the amount of CO2 formed.

But to find the amount of CO2 formed, we have to write out the equation for this reaction. The type of reaction depicted here is combustion, where oxygen gas reacts with a substance to form carbon dioxide and water. And we also know that this equation must be balanced, according to the Law of Conservation of Matter. It is as follows:

CH4 + 2 O2 => CO2 + 2 H2O.

Now that we have the equation of the reaction, we can now find which of the two reactants is the limiting reactant. To do this, we need to convert the volumes of methane and oxygen gas to moles. Simply use the Ideal Gas Law to do this, and you get:

Methane Gas: .189 mol     |     Oxygen Gas: 1.75 mol

Using the equation, we can then see that methane gas is the limiting reactant.

We know, also due to the equation that 1 mol of CO2 is produced for every mol of methane gas. This gives us the answer of .189 mol of CO2 produced. But remember, the question asks us for the volume of CO2 produced, so we must apply the Ideal Gas Law once again, getting the answer of 2.47 L. CO2.

A system does 125 J of work and cools down by releasing 438 J of heat. The change in internal energy is ____________ J.

Answers

Given that,

Work done by the system = 125 J

Energy released when it cools down = 438 J

To find,

The change in internal energy.

Solution,

As heat is released by the system, Q = -438 J

Work done by the system, W = -125 J

Using the first law of thermodynamics. The change in internal energy is given by :

[tex]\Delta U=Q-W\\\\=-438-125\\\\=-563\ J[/tex]

So, the change in internal energy is 563 J.
