Answers
Answer:
–253.5 °C
Explanation:
We'll begin by calculating the number of mole in 6 g of CO₂. This can be obtained as follow:
Molar mass of CO₂ = 12 + (2×16)
= 12 + 32
= 44 g/mol
Mass of CO₂ = 6 g
Mole of CO₂ =.?
Mole = mass / molar mass
Mole of CO₂ = 6 / 44
Mole of CO₂ = 0.136 mole
Next, we shall convert 225 mL to L.
1000 mL = 1 L
Therefore,
225 mL = 225 mL × 1 L / 1000
225 mL = 0.225 L
Next, we shall determine the temperature of the gas. This can be obtained as follow:
Pressure (P) = 0.855 atm
Volume (V) = 0.225 L
Number of mole (n) = 0.136 mole
Gas constant (R) = 0.0821 atm.L/Kmol
Temperature (T) =?
PV =nRT
0.855 × 0.255 = 0.136 × 0.0821 × T
0.218025 = 0.0111656 × T
Divide both side by 0.0111656
T = 0.218025 / 0.0111656
T = 19.5 K
Finally, we shall convert 19.5 K to degree celsius (°C). This can be obtained as follow:
T(°C) = T(K) – 273
T(K) = 19.5 K
T(°C) = 19.5 – 273
T(°C) = –253.5 °C
Therefore, the temperature of the gas is –253.5 °C

If I plant a green bean seed in the desert, will it grow thick, barrel-shaped stems full of water like a cactus? Why or why not?
Answers
Answer:
No, although the bean crop can grow perfectly in full sun or a little shade in very warm places. It does not mean that they will adopt the growth patterns of the cactus, especially because this plant needs constant watering (in small quantities), very constant. Beans require good drainage for their growth.
Each vegetation have its own characteristics and the power of adaptation. A green bean cannot survive in a desert like a cactus in desert without water. It can only grow thick in soil with proper water content and nutrients.
What is cactus?Cactus is a type of plant grow in dry regions such as deserts. It can adapt in deserts without water for long time because, the plant have enough water storage in its stem.
Domestic vegetation such as bean, pea, nuts etc ill not grow in dry regions because they cannot adapt in deserts without water. The soil in deserts is dry and have no nutrients.
These conditions prevent the growth of vegetables in desert areas. Moreover, desert have summer season only. The extreme temperature over there will cause the normal plants to diminish.
Therefore, planting green bean in deserts will not make it grow thick like a cactus plant.

The total pressure of all the gases inside a metal container is 9.8 atm. If the partial pressure of the oxygen in the container is 4.2 atm, what is the partial pressure of the rest of the gases in the container other than the oxygen?
Answers
In a container, the sum of partial pressures equals the total pressure. If the sun is 9.8 atm and the partial pressure of oxygen is 4.2 atm, the rest of the gases must account for the other 5.6 atm.
5.6 atm is the partial pressure of the rest of the gases in the container other than the oxygen.
What is partial pressure?Each gas in a mixture adds to the overall pressure of a mixture. This portion represents the pressure. The pressure a gas would have if it were in its own volume and at its own temperature is known as the partial pressure. According to Dalton's law, the pressure distribution of an ideal gas mixture is equal to the combined partial pressures of the component gases.
The study of partial pressure is significant in the domains of physics, chemistry, and biology. The partial pressure of oxygen or carbon dioxide in the blood is used to calculate blood levels of each substance. The overall pressure in a container is equal to the sum of the partial pressures. The remaining gases must make up the remaining 5.6 atm if the oxygen partial pressure equals 4.2 atm and the sun reaches 9.8 atm in pressure.
Therefore, 5.6 atm is the partial pressure of the rest of the gases in the container other than the oxygen.

Explanation:
By using gas law , the volume will be 61.9 mL .
What is gas law?
According to the gas law, the pressure of a gas generally directly proportional to its temperature at a fixed volume.
Gas law can be represented as:
[tex]P_{1} V_{1}/ T_{1} = P_{2} V_{2} / T_{2}[/tex]
Calculation of volume with the aid of gas law:
It is given that, [tex]P_{1}[/tex] = 45.8 kPa, [tex]P_{2}[/tex] = 99.3 kPa , [tex]T_{1}[/tex] = 57.2°C, [tex]T_{2}[/tex] = 112.3°C, [tex]V_{1}[/tex] = 115 mL .
Now, put the values of given data in gas laws equation.
(45.8kPa)(115mL)/(330K)= (99.3kPa)([tex]V_{2}[/tex])(385.3K)
[tex]V_{2}[/tex] = 61.9 mL
Therefore, the volume will be 61.9 mL .

A gas has a pressure of 760 torr at 21 degrees Celsius. What is the pressure of the gas at 250 degree Celsius.
Answers
Answer:
Given,
P1=760 torr
T1=21°C
T2=250°C
P2=?
Solution,
According to Gay-Lussac's Law or Third Gas Law,
P1T2=P2T1
760×250=21×P2
P2=9047 torr
9047 is the pressure of the gas at 250 degree Celsius.
Answer:
9,047.62 torr
Explanation:
The given parameters are pressure (P1) = 760 torr, Temperature at which the gas exerts pressure, P1, called the initial temperature (T1) = 21-celsius degrees, a second temperature(T2) = 250 Celsius degrees, and the pressure(P2) which such gas would exert at T2 is unknown [P2=?]. Notice that the temperature difference.
Gay Lussac's Law states that the pressure of a given amount of gas held at constant volume is directly proportional to the kelvin temperature.
If you heat a gas, the molecule gains kinetic energy and they move about in their container. As the temperature increase, the energy each particle gains would increase as well. Thus, allowing them to move faster and in all directions. Because they are confined to the boundary of the container, the gas particles bounce off the wall of the container. The energy allows continuous movement of the particle. Hence, the pressure each particle would exert on the wall of the container is equal to its momentum. Remember that the velocity, V, a particle is traveling with is promotional to the energy, E, that it obtains from the increase in temperature.
Using the Gay Lussac's Law equation: P1T2=P2T1 [Notice here that P=T].
Making P2 the mathematical subject, P2= P1T2/T1. ----Formula for the condition of this problem.
Substituting the known values;
P2= (760 torr x 250°C)/ 21 °C
P2= (190,000 °C torr)/21 °C
Cancel like terms in the numerator and denominator.
P2= (190,000 torr)/21
P2= 9,047.62 torr
[Notice that the pressure increase with the increase in temperature. The pressure increase from 760 torr to 9,047.62 torr with an increase in temperature from 21 Celsius degrees to 250 Celsius degrees.]

Answers
Answer:
[tex]\Rightarrow V_2 = 389mL[/tex]
Explanation:
To solve this question, we could use Charles' law since both the number of mole and pressure are constant
At STP pressure P = 760 tor and Temperature = 273K
V1 =425mL, T1 =298K and T2 =273K
and [tex]\frac{V_1}{T_1} =\frac{V_2}{T_2}[/tex]
[tex]\Rightarrow V_2 =T_2\times\frac{V_1}{T_1}[/tex]
[tex]\Rightarrow V_2 =273\times\frac{425}{298}[/tex]
Therefore, [tex]\Rightarrow V_2 = 389mL[/tex]
