At constant temperature, if the volume of the sample of gas decreases, the pressure increases to 4.0atm.
Hence, option1)4 atm is the correct answer.
What is Boyle's law?Boyle's law simply states that "the volume of any given quantity of gas is inversely proportional to its pressure as long as temperature remains constant.
Boyle's law is expressed as;
P₁V₁ = P₂V₂
Where P₁ is Initial Pressure, V₁ is Initial volume, P₂ is Final Pressure and V₂ is Final volume.
Given the data in the question question;
Initial volume of the gas V₁ = 200mL = 0.2LInitial pressure of the gas P₁ = 1.0atmFinal volume of the gas V₂ = 50.mL = 0.05LFinal pressure of the gas P₂ = ?We substitute our given values into the expression above to determine the new pressure.
P₁V₁ = P₂V₂
P₂ = P₁V₁ / V₂
P₂ = ( 1.0atm × 0.2L ) / 0.05L
P₂ = 0.2Latm / 0.05L
P₂ = 4atm
At constant temperature, if the volume of the sample of gas decreases, the pressure increases to 4.0atm.
Hence, option1)4 atm is the correct answer.

During the Viking landings on Mars, the atmospheric pressure was determined to be on the average about 6.50 millibars (1 bar = 0.987 atm). What is that pressure in torr and kPa?
Answers
Answer:
The pressure is equal to 4.87 torr and 0.649 kPa.
Explanation:
The atmospheric pressure was determined to be on the average about 6.50 millibars.
As 1 bar = 0.987 atm
6.5 mbar = 0.0065 bar
So,
0.0065 bar = (0.0065×0.987 ) atm
= 0.0064155 atm
Since, 1 atm = 760 torr
So, 0.0064155 atm = 4.87 torr
Since, 1 torr = 133.322 Pa
4.87 torr = 649.27 pa
or
4.87 torr = 0.649 kPa
Hence, the required pressure is equal to 4.87 torr and 0.649 kPa.

Answers
The question is incomplete, the complete question is;
When a lead acid car battery is recharged by the alternator, it acts essentially as an electrolytic cell in which solid lead(II) sulfate PbSO₄ is reduced to lead at the cathode and oxidized to solid lead(II) oxide PbO at the anode.
Suppose a current of 96.0 A is fed into a car battery for 37.0 seconds. Calculate the mass of lead deposited on the cathode of the battery. Round your answer to 3 significant digits. Also, be sure your answer contains a unit symbol.
Answer:
3.81 g of lead
Explanation:
The equation of the reaction is;
Pb^2+(aq) + 2e ---->Pb(s)
Quantity of charge = 96.0 A * 37.0 seconds = 3552 C
Now we have that 1F = 96500 C so;
207 g of lead is deposited by 2 * 96500 C
x g of lead is deposited by 3552 C
x = 207 * 3552/2 * 96500
x = 735264/193000
x = 3.81 g of lead

Explanation:
Hello there!
In this case, for the chemical reaction:
[tex]H_2O(g) CO(g)\rightleftharpoons CO_2(g) H_2(g)[/tex]
It is widely known that the the only factor altering the equilibrium constant is the temperature because of its thermodynamic definition:
[tex]K=exp(-\frac{\Delta G(T)}{RT} )[/tex]
Which is temperature dependent on the denominator and on the Gibbs free energy of reaction. In such a way, the answers can be just f and g, as the other factors modify Q (reaction quotient) rather than K. Thus, we can discuss about f and g:
f. This would increase K if the Gibbs free energy of reaction is positive (nonspontaneous).
g. This would increase K if the Gibbs free energy of reaction is negative (spontaneous).
It is important to discuss those two because the Gibbs free energy is not given.

Consider the reaction, C2H4(g) + H2(g) - C2H6(8), where AH = -137 kJ. How many kilojoules are released when 3.5 mol of CH4
reacts?
480 kJ are released
20 x 103 kJ are released
570 kJ are released
137 kJ are released
Answers
Answer: 480 kJ of energy is released when 3.5 mol of [tex]C_2H_4[/tex] reacts.
Explanation:
The balanced chemical reaction is:
[tex]C_2H_4(g)+H_2(g)\rightarrow C_2H_6(g)[/tex] [tex]\Delta H=-137kJ[/tex]
Thus it is given that the reaction is exothermic (heat energy is released) as enthalpy change for the reaction is negative.
1 mole of [tex]C_2H_4[/tex] on reacting gives = 137 kJ of energy
Thus 3.5 moles of [tex]C_2H_4[/tex] on reacting gives = [tex]\frac{137}{1}\times 3.5=480 kJ[/tex] of energy
Thus 480 kJ of energy is released when 3.5 mol of [tex]C_2H_4[/tex] reacts.

What is the temperature of an 11.2-L sample of carbon monoxide, CO, at 744 torr if it occupies 13.3 L at 55 °C and 744 torr? 3C The pressure is not changing, so it looks like a case where charles’ law can be use.
Answers
Answer: The tempearture of 11.2 L of CO is [tex]3.0^0C[/tex].
Explanation:
To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]
where,
[tex]V_1\text{ and }T_1[/tex] are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
[tex]V_1=11.2L\\T_1=?\\V_2=13.3L\\T_2=55^0C=(55+273)K=328K[/tex]
Putting values in above equation, we get:
[tex]\frac{11.2L}{T_1}=\frac{13.3L}{328K}\\\\T_1=276K=(276-273)^0C=3.0^0C[/tex]
Thus the tempearture of 11.2 L of CO is [tex]3.0^0C[/tex], pressure remaining constant.

Explanation:
An alternating current is an electrical current in which the current changes its magnitude and the sense cyclically. The frequency of this current is defined as the cycles that the current completes in one second.
As the current completes 100 cycles in 0.1 seconds, the frequency is:
100 cycles / 0.1s = 1000 cycles /s
The frequency is 1000 cycles/s
What is the formula mass of ZrF4?
Answers
Answer:
167.217g/mol
Explanation:
Formula mass is defined as the mass in grams that a mole of a molecule weighs. To solve the formula mass of ZrF₄ we require the molar mass of Zr and of F (Molar mass Zr: 91.225g/mol; F: 18.998g/mol)
In this molecule, there is 1 mole of Zr and 4 moles of F. The formula mass is:
Zr = 1*91.225g/mol = 91.225g/mol
F = 4*18.998g/mol = 75.992g/mol
Formula mass: 91.225g/mol + 75.992g/mol

The method of heat transfer that occurs when particles move
through a fluid is called
Answers
Answer:
Convection
Explanation:
Convection definition:
the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
The method of heat transfer that occurs when particles move through a fluid is called convection.
Convection relies on the principle of fluid flow, where hotter particles become less dense and rise while cooler particles sink due to their increased density.
This movement creates a continuous circulation of the fluid, enabling the transfer of thermal energy. As the hot particles rise, they carry their thermal energy with them, and as the cooler particles sink, they absorb heat from their surroundings.
Convection is also observed in natural phenomena such as ocean currents, air currents, and even the movement of magma in the Earth's mantle.
