A gas is confined to a steel tank with a fixed volume . At 293 K, the gas exerts a pressure of 8.53 atm. After heating the tank , the pressure of the gas increases to 10.4 atm. What is the temperature of the heated gas?

Answers

Answer: The temperature of the heated gas is 357 K

Explanation:

To calculate the final temperature of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

[tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}[/tex]

where,

[tex]P_1\text{ and }T_1[/tex] are the initial pressure and temperature of the gas.

[tex]P_2\text{ and }T_2[/tex] are the final pressure and temperature of the gas.

We are given:

[tex]P_1=8.53atm\\T_1=293K\\P_2=10.4atm\\T_2=?[/tex]

Putting values in above equation, we get:

[tex]\frac{8.53}{293K}=\frac{10.4}{T_2}\\\\T_2=357K[/tex]

Hence, the temperature of the heated gas is 357 K

What advantage does gasoline have over electricity for cars?

Answers

You don’t have to stop & charge so often , you can just fill up & go

Final answer:

Gasoline has a higher energy density than electricity stored in lithium-ion batteries, enabling more energy to be carried per unit of weight. Gasoline vehicles can refuel quickly, offering convenience for long-distance travel, while electric vehicles require longer recharge times. Additionally, gasoline's safety profile is relatively high given its energy content, as it burns rather than explodes.

Explanation:

One of the main advantages that gasoline has over electricity for powering cars is its higher energy density. Gasoline contains approximately 13 kWh/kg, while the energy density of lithium-ion batteries is about 0.2 kWh/kg, which is substantially lower. This means that gasoline can deliver more energy per unit of weight than batteries can, making it a more energy-dense fuel source.

An additional advantage is the rapid refueling capability of gasoline vehicles. A car can fill its tank with gasoline at a rate of 15 MW, allowing it to be ready for further travel in a matter of minutes, whereas electric cars often require hours to fully recharge. This convenience factor is a significant benefit for long-distance travel or in situations where quick refueling is necessary.

Safety is another aspect where gasoline has an advantage. Although gasoline is flammable, it is not as explosive as one might think—the vapor mix with oxygen burns rather than explodes, making it relatively safe for an energy source with such high energy content.

18g
36g
72g
144g

Answers

Answer: 72 g of [tex]H_2O[/tex] is formed.

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} O_2=\frac{64}{32}=2moles[/tex]

[tex]2H_2+O_2(g)\rightarrow 2H_2O[/tex]

As  [tex]H_2[/tex] is the excess reagent, [tex]O_2[/tex] is the limiting reagent as it limits the formation of product.

According to stoichiometry :

1 mole of [tex]O_2[/tex] produce=  2 moles of [tex]H_2O[/tex]

Thus 2 moles of [tex]O_2[/tex] will require=[tex]\frac{2}{1}\times 2=4moles[/tex]  of [tex]H_2O[/tex]

Mass of [tex]H_2O=moles\times {\text {Molar mass}}=4moles\times 18g/mol=72g[/tex]

How much heat is required to heat 9.61g of ethanol (CH3CH2OH) from 24.10C to 67.30C?

Answers

Answer:

a.)  

To warm the liquid from 35°C to 78°C:

(2.3 J/g-K) x (42.0 g) x (78 - 35) = 4154 J

To vaporize the liquid at 78°C:

(38.56 kJ/mol) x (42.0 g C2H5OH / 46.06867 g C2H5OH/mol) = 35.154 kJ

Total:

4.154 kJ + 35.154 kJ = 39.3 kJ

b.)  

To warm the solid from -155°C to -114°C:

(0.97 J/g-K) x (42.0 g) x (-114°C - (-155°C)) = 1670 J

To melt the solid at -114°C:

(5.02 kJ/mol) x (42.0 g C2H5OH / 46.06867 g C2H5OH/mol) = 4.5766 kJ  

To warm the liquid from -114°C to 78°C:

 1021.27 J heat is required to heat 9.61g of ethanol from 24.1⁰C to 67.3⁰C

What is Specific Heat?

The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius.

It is a measure of how much energy it takes to raise the temperature of a substance. It is the amount of heat necessary to raise one mass unit of that substance by one temperature unit.

It is given by the formula -

                                                  Q = mcΔT

where, Q = amount of heat

m = mass

c = specific heat

ΔT = Change in temperature

Given,

Mass of ethanol = 9.61g

Initial temperature = 24.1⁰C

Final temperature = 67.3⁰C

Q = mcΔ T

        = 9.61 × 2.46 × ( 67.3 - 24.1)

         = 1021.27 J

Therefore,  1021.27 J heat is required to heat 9.61g of ethanol from 24.1⁰C to 67.3⁰C

think about the statement "there is no new water on earth" write at least 5 sentences describing how there can be no new water on earth, but the earth doesn't run out of water.

Answers

Earth contains huge quantities of water in its oceans, lakes, rivers, the atmosphere, and believe it or not, in the rocks of the inner Earth. Over millions of years, much of this water is recycled between the inner Earth, the oceans and rivers, and the atmosphere. This cycling process means that freshwater is constantly made available to Earth's surface where we all live. Our planet is also very efficient at keeping this water. Water, as a vapor in our atmosphere, could potentially escape into space from Earth. But the water doesn't escape because certain regions of the atmosphere are extremely cold. (At an altitude of 15 kilometers, for example, the temperature of the atmosphere is as low as -60° Celsius!) At this frigid temperature, water forms solid crystals that fall back to Earth's surface.
Many people live faraway from freshwater sources. They need to carry their water home.
While our planet as a whole may never run out of water, it's important to remember that clean freshwater is not always available where and when humans need it. In fact, half of the world's freshwater can be found in only six countries. More than a billion people live without enough safe, clean water.
Also, every drop of water that we use continues through the water cycle. Stuff we put down the drain ends up in someone or something else's water. We can help protect the quality of our planet's freshwater by using it more wisely.

Explain what domain would best be represented by the "?" in the diagram.

B) Eukarya because the organisms are all prokaryotic.
C) Bacteria because some of the organisms are autotrophs.
D) Archaea because the organisms are all diverse bacteria.

Answers

Final answer:

The correct answer is 'Eukarya because the organisms are all eukaryotic' since the organisms mentioned have cells with nuclei. Bacteria and Archaea are both prokaryotic and do not contain organisms with eukaryotic cells.

Explanation:

The correct answer to the question is A) Eukarya because the organisms mentioned are all eukaryotic. This means that the cells of these organisms contain nuclei. The domain Eukarya includes diverse groups such as animals, plants, fungi, and protists. These kingdoms are distinguished by the presence of eukaryotic cells, which differentiate them from prokaryotic cells found in the other two domains, Bacteria and Archaea, both of which lack a nucleus. Bacteria and Archaea are known as prokaryotes and often consist of single-celled organisms. Eukarya, on the other hand, can consist of both unicellular and multicellular organisms. Therefore, Option B 'Eukarya because the organisms are all prokaryotic' is incorrect as eukaryotes have a nucleus. Option C 'Bacteria because some of the organisms are autotrophs' is not correct either since autotrophy is not exclusive to Bacteria and does not define domain classification on its own. Lastly, Option D 'Archaea because the organisms are all diverse bacteria' is incorrect because Archaea is a separate domain, and it encompasses organisms that are genetically distinct from bacteria and eukaryotes, despite their prokaryotic cell structure.

what is the total number of moles of solute in 2230 ml of 3.0 M NaOH solution.

Answers

The total number of moles of solute in 2230 mL of a 3.0 M NaOH solution is calculated by converting the volume to liters and multiplying by the molarity, resulting in 6.69 moles of NaOH.

The total number of moles of solute in 2230 mL of 3.0 M NaOH solution can be calculated by using the definition of molarity, which is the number of moles of solute per liter of solution. The following steps are used for the calculation:

Convert the volume from milliliters (mL) to liters (L), knowing that 1 L = 1000 mL.Multiply the volume in liters by the molarity (M) to find the total moles of solute.

First, convert 2230 mL to liters: 2230 mL
1000 mL/L = 2.23 L.

Next, multiply the volume by the molarity: 2.23 L × 3.0 M = 6.69 moles of NaOH.

Therefore, the correct answer is that there are 6.69 moles of NaOH in 2230 mL of a 3.0 M NaOH solution.

Explanation:

In this nuclear reaction, both the atomic number and the atomic mass must be conserved. For atomic numbers (proton numbers), you add the atomic numbers on one side of the equation and set it equal to the sum of atomic numbers on the other side. The same thing applies to atomic mass (proton + neutron numbers). However, the nuclear reaction is not complete.

This question is seeking to determine the missing particle in this nuclear reaction involving potassium (K). The missing part of the nuclear equation would help us determine the product particles after a certain type of nuclear decay. Unfortunately, the reaction is not completely given, if it were we could utilize conservation laws to identify the missing particle.
